• Check for availabilty.
• Ideal choice where shaft not practical to use as inner
raceway.
• Provided in inch nominal dimensions for use with inch series
heavy-duty needle roller bearings.
• Designed to meet established inch tolerances.
• Selected size should be wider than matching drawn cup
• Maximum shaft fillet radius (ras max) cannot exceed inner ring
bore chamfer (rs min) as shown.
• Optional centralized lubrication groove (bore) or through-hole
available – specify when ordering.
• Designed to be axially clamped against shoulder for loose
transition fit on shaft.
• After mounting, for tight transition fit (keeping inner ring from
rotating relative to shaft), inner ring O.D. must not exceed
raceway diameter on matching bearing.

NEEDLE Roller Bearings
Inner Rings – continued
Inch Series
• Check for availabilty.
• Ideal choice where shaft not practical to use as inner
raceway.
• Provided in inch nominal dimensions for use with inch series
heavy-duty needle roller bearings.
• Designed to meet established inch tolerances.
• Selected size should be wider than matching drawn cup
• Maximum shaft fillet radius (ras max) cannot exceed inner ring
bore chamfer (rs min) as shown.
• Optional centralized lubrication groove (bore) or through-hole
available – specify when ordering.
• Designed to be axially clamped against shoulder for loose
transition fit on shaft.
• After mounting, for tight transition fit (keeping inner ring from
rotating relative to shaft), inner ring O.D. must not exceed
raceway diameter on matching bearing.

Stud Type and Yoke Type Track Rollers
track rollers
Overview: Track rollers (also known as cam followers) are characterized by their thick-walled outer
rings that run directly on a track. The thick outer rings permit high load-carrying capability while
minimizing both distortion and bending stresses. Sealed designs with internal thrust washers help
extend service life under conditions of infrequent lubrication.
• Sizes: 16 mm - 110 mm (1/2 in. - 4 in.) bore.
• Markets: Ram support rollers, material handling and indexing equipment.
• Features: Available in two basic designs: with an inner ring for straddle mounting
in a yoke or with an integral stud for cantilever mounting.
CA
• Benefits: High load-carrying capability with minimized distortion and bending stresses.
Extended service life under conditions of infrequent relubrication.

Stud Type and Yoke Type Track Rollers
Construction
Stud Type Track Rollers
The metric series stud type track roller is a non-separable
unit, consisting of a large radial cross-section outer ring, needle
roller and cage radial assembly or a full complement of needle or
cylindrical rollers, a stud and a retaining washer securely fastened
to the stud.
Some applications may require more secure positioning than
provided by the tightened stud nut. If so, it is recommended that
the mounting hole and the eccentric bushing be drilled at the time
of installation to accept a locating dowel pin.
The seals on the sealed stud type track rollers are located in the
counterbores of the outer ring and seal against the stud flange and the
retaining washer, providing good retention of lubricant and exclusion
of foreign material. The seals are thermally stable in a temperature
range between -30˚ C and 110˚ C.
A screwdriver slot (standard) or a hexagonal wrench socket
(customer requested) in the head of the stud facilitates mounting.
Wrench sizes are listed on the dimensional tables where found among
certain GC Series sizes on pages later in this section. Other metric
series hexagonal socket sizes are listed in Table 1.

Eccentric Studs For Stud Type Track Rollers
To provide radial adjustment of the outer ring toward the track or
cam surface at the time of installation, some metric series stud type
track rollers are available with eccentric studs which are specified
by adding the letter “E” to the designation letters: KRE and NUKRE.
The GCR and GCUR Series include an eccentric bushing added to
the track roller stud. Appropriate dimensions of the eccentric stud
bushing are listed in Table 2 and 2A.
Since a track roller with an eccentric stud is usually adjusted
upon installation by turning the stud in the mounting hole, a close
clearance fit between the outside diameter of the bushing and
the mounting hole is necessary. For turning the stud, a hexagonal
wrench is generally more convenient than a screwdriver, thus,
the option of a hexagonal wrench socket in the head of the stud
should be considered.

NEEDLE Roller Bearings
Yoke Type Track Rollers
Metric Series Yoke Type Track Rollers
Without End Washers
These yoke type track rollers are available with a profiled or a
cylindrical outside diameter of the outer ring, and with or without a
separable inner ring. Since they are supplied without end washers,
their outer rings must be guided by the adjacent end locating
surfaces. Tolerance class F6 is the normal specification for the
bore of the metric series needle roller and cage radial assemblies
used with these yoke type track rollers.
Yoke Type Track Rollers – Series RSTO & STO
C
Series STO have a separable inner ring and when the inner
ring is removed they become series RSTO. They run directly on a
hardened and ground inner raceway. Quality requirements for inner
raceways are given in the engineering section of this catalog.
Sealed Yoke Type Track Rollers Without End
Washers – Series RNA 22.2RS & NA22.2RS
These yoke type track rollers have the same bore diameter and
outside diameter as most of the other metric series yoke type track
rollers listed in this catalog. The thick section outer ring is made
of one-piece channel-shaped bearing quality steel, heat treated to
yield maximum load carrying capability. The integral end flanges
provide axial guidance for the large diameter needle rollers, and
a cage supplies their inward retention. These track rollers have
two integral lip contact seals designated by .2RS. The seals are
thermally stable in a temperature range between -30° C and 110° C.
Care should be exercised when mounting track rollers without
inner rings onto inner raceways to avoid damage to the seals.

Metric Series Yoke Type Track Rollers With
End Washers
Yoke Type Track Rollers – Series NATR & STO.ZZ
The series NATR yoke type track rollers are of non-separable
design consisting of a crowned or a cylindrical outer ring, caged
needle rollers, an inner ring and two retaining end washers securely
fastened to the inner ring. The series STO.ZZ yoke type track rollers
are of separable design with two loose end washers. These end
washers placed in the counter bores of the outer ring form very
effective labyrinth type shields, providing good retention of lubricant
and exclusion of foreign material. A lubrication hole in the inner
ring enables relubrication when a cross-drilled bolt or shaft, which
can be serviced from the end, is used.
•

These yoke type track rollers are available with a crowned or
a cylindrical outside diameter of the outer ring. Metric series yoke
type track rollers with end washers, depending on the internal
construction, may be end guided, either through the end washers
or between the end faces of the rollers and the inside faces of the
outer ring flanges.

Yoke Type Track Rollers – Series NUTR
The series NUTR yoke type track rollers are of non-separable
design consisting of a profiled or cylindrical outer ring, two rows of
full complements of cylindrical rollers, an inner ring, two retaining
end washers and two shields. The outer ring is located axially
through the cylindrical rollers.
A lubricating hole in the inner ring enables relubrication when
a cross-drilled bolt or shaft, which can be serviced from the end,
is used.
The smallest track roller of this series has an outside diameter
of 35 mm. NUTR yoke type track rollers are well suited to carry
high loads and designs with a thicker outer ring are particularly
suitable for high shock loads. Designs with thicker outer ring have
a larger outside diameter which can be identified by the bearing
designation (e.g., NUTR 1542).
Yoke type track rollers – series FP and FG
The FP and FG non-separable inner ring designs are available in
profiled or cylindrical outer rings. Both employ a full complement
of needle rollers and require relubrication via a pathway through
the shaft. The FP Series is the smallest series available and is not
offered with seals.
Yoke type track rollers – series FGU
(Light and Heavy types)
The FGU non-separable inner ring desings are available
in profiled or cylindrical outer rings. All FGU Series use a full
complement of cylindrical rollers between the inner and outer rings
and require relubrication via a pathway through the shaft. The FGU
Heavy series uses a thicker outer ring section and are capable of
higher loads.
Both FGU Series are only available with a metal shield for a
roller sealing option.
Yoke type track rollers – series RNA, RNAB,
RNAL
The RNA and RNAB Series design use a full complement of
needle rollers retained with a pair of end washers. A separate,
matching inner ring is listed in the tables of part numbers. The
RNAL Series use a cylindrical outer ring and is only offered in
limited sizes.
Stud Type and Yoke Type Track Rollers
Dimensional Accuracy
given in Table 3. The inner ring tolerances given in Table 5 apply to
inner rings used in metric series caged roller, NUKR Series yoke
type track rollers.
The tolerances of the basic metric series caged roller and NUKR
stud type and yoke type track rollers whose outer rings have a
cylindrical outside diameter, correspond to tolerances specified
in ISO-492 Radial bearings - Tolerances. The outer ring tolerances
given in Table 4 apply to the outer rings used in the caged roller and
NUKR stud type and caged roller and NUTR yoke type, metric series,
track rollers. Metric series track rollers with a crowned outside
diameter are the exception: their outside diameter tolerances is 00.05 for all caged roller sizes and NUTR, NUKR types. The remaining
types have h9 tolerance on profiled outer diameters and h7 for
straight diameters. Stud diameter and stud length tolerances are
Mounting Stud Type Track Rollers
When the stud shank of a metric series stud type track roller is
mounted in a hole of tolerance H7, the installation force should be
applied only to the center portion of the flanged end of the stud,
preferably with an arbor press. The surface of the hole in the
machine element which supports the stud must not deform under
the expected load, and the support should be sufficiently rigid to
resist bending loads. Deformation and bending will cause uneven
loading of the outer ring.
In mounting the stud type track roller, the retaining washer must
be firmly backed up by a flat shoulder which is square with the stud
center line. The shoulder diameter must be no smaller than the
minimum clamping diameter, da listed in the tabular data.
The maximum inherent strength of the stud is obtained when
the track roller is supported as close as possible to the retaining
washer, which minimizes the bending moment. For this reason the
edge of the housing which supports the stud shank should be kept
as sharp as practical, but free from burrs.
The clamping nut should not be tightened with a torque value
higher than the maximum listed. A screwdriver slot or hexagonal
wrench socket in the flanged end of the stud is provided for a tool
to prevent the stud from turning when the nut is being tightened.
Hexagonal nuts are supplied with all metric series stud type track
rollers.

NEEDLE Roller Bearings
Yoke Type Track Rollers
C
The machine element with the holes in which the mounting
bolt or shaft is supported must be sufficiently rigid to resist local
crushing under the applied load, and to resist bending which can
cause uneven loading of the needle rollers.
When applied loads are high, the h6 or j6 tolerance should be
used in conjunction with a high strength shaft or bolt for mounting
metric series yoke type track rollers. When loads are moderate,
a g6 tolerance may be used with a high strength shaft or bolt. For
light loads, the loose transition fit with the f6 tolerance may be used
with an unhardened shaft or bolt.
The yoke type track rollers with inner rings, also those with
end washers as well as inner rings, should be clamped endwise
between parallel faces perpendicular to the axis to prevent the
retaining washers from coming off under load. The dimensions of
machine parts adjoining the metric series yoke type track rollers
should be based on the minimum clamping diameter da to ensure
that the washers are adequately supported. If the track roller
cannot be end clamped, a close axial fit in the yoke is required.
Care should be taken that the lubricating hole is located in the
unloaded zone of the raceway.
The metric series yoke type track rollers without inner rings
require a hardened and ground shaft or bolt with a k5 tolerance.
Inner raceway quality requirements are given in the engineering
section of this catalog.
Load Ratings
Dynamic Loading As A Track Roller
When the outer ring of a stud type or yoke type track roller
runs on a track, the contact, under a radial load, causes elastic
(oval) deformation of the outer ring. As a result, a smaller zone of
the raceway is loaded and the load is distributed on fewer needle
rollers. This in turn affects the dynamic and static load ratings of
the track rollers. Also, this deformation generates bending stress
in the outer ring which must not exceed the maximum permitted for
the material of the outer ring. The maximum permissible dynamic
(Fr perm) radial load condition is determined by this requirement.
The rating life of stud type or yoke type track rollers should be
calculated using the dynamic load ratings Cw shown in the tables.
The tables also show the maximum permissible radial load, Fr perm
that can be dynamically applied on stud type or yoke type track
rollers. However, to calculate the L10 life of a track roller, the
applied radial load must not be greater than Cw/2 based on ideal
operating conditions of alignment, lubrication, temperature, speed,
and accelerations.
Static Rating As A Track Roller
In addition to the basic static load rating C0, the tables also list
the maximum permissible static radial load F0r perm that may be
applied to a stud type or yoke type metric series track roller. The
values of F0r perm result in a calculated minimum static factor fs of 0.7
for the worst condition of internal load distribution in metric series
track roller operation. The F0r perm values must not be exceeded. The
static factor fs can be calculated using the following formula:
fs ≥ 0.7 •
F0r perm
P0r
where
F 0r perm = Maximum permissible static radial load (kN)
= Equivalent static load (kN)
P0r
P0r = F0r for metric series track rollers
F0r
= Static radial load (kN)
= Static factor whose values should not be fs
smaller than those suggested in Table 6.

Stud Type and Yoke Type Track Rollers
Lubrication Of Stud Type
Track Rollers
t1-0,1
Timken metric series stud type track rollers are supplied with a
lithium soap based, general purpose grease. When the caged KR
Series track rollers are operated at low speeds, with light loads
and in clean environments, there often is no need to relubricate
the track roller. In other applications, periodic relubrication may
be necessary to obtain optimum performance. The full complement
series of track rollers have less internal volume available for
grease storage, therefore, they may require more frequent
lubrication than caged type track rollers. Stud type track rollers,
with a screwdriver slot in the flanged end of the stud, have
provisions for relubrication through the flanged end of the stud.
Metric series stud type track rollers with hexagonal sockets can
not be relubricated from the flanged end of the stud. Both types of
metric series stud type track rollers, with outside diameters larger
than 22 mm (28 mm for all GC variations), allow for relubrication
through the threaded end of the stud. In addition, caged roller and
NUKR Series stud type track rollers with 30 mm and larger outside
diameters allow for relubrication through a cross-drilled hole in the
stud shank. The ends of the axial holes are counterbored to accept
press-fit grease fittings of series VENN. The grease fittings are
supplied with metric series stud type track rollers. Hole diameters
(d4) for these grease fittings are listed in the tables of dimensions
on pages later in this chapter as it applies. Note that the GC small
series has no axial hole.
One or more plugs are supplied with every metric series stud
type track roller to close off unused holes. At the flanged end,
the plug must not be pushed in too deeply as it may cover the
cross-drilled lubricating hole. The plug should be pressed in using
an installation tool whose dimensions are given in Table 8. If the
cross-drilled hole in the stud shank is not used, it will be covered
when the track roller is properly installed.
dD-0,1 d4-0,1 dE-0,1
t +0,2
During installation of the track roller it will be desirable to ensure
that the cross drilled hole is positioned in the unloaded zone of the
track roller raceway. The location of the cross-drilled hole can be
best recognized by its alignment with the manufacturer's stamp
or parallel to the screwdriver slot, in certain cases.
Lubrication Of Yoke Type
Track Rollers
Yoke type track rollers are produced with a lubricating hole in
the inner ring so they can be relubricated through a cross-drilled
hole in the supporting shaft or bolt. When mounting yoke type track
rollers, care should be taken that the lubrication hole is located in
the unloaded raceway zone.
Oil is the preferred lubricant for yoke type track rollers.
Continuous oil lubrication or frequent grease lubrication should be
used for steady rotating conditions. Applications involving slow,
intermittent oscillations are not as critical, and longer intervals
between relubrication are permitted. Sealed yoke type track
rollers are normally supplied with an initial charge of a medium
temperature grease. Caged yoke type track rollers have maximum
grease storage capacity and, consequently, longer pregreased life
than full complement types.

NEEDLE Roller Bearings
Stud Type And Yoke Type Track
Rollers
Inch Series
Inch series track rollers listed in this catalog have been
designed with the outer rings of large radial cross section to
withstand heavy rolling or shock loads on track type or camcontrolled equipment.
Reference standard:
• ANSI/ABMA Std. 18.2 – Needle roller bearings – radial, inch design.
Before selecting specific inch series track rollers, the engineering
section of this catalog should be reviewed.
C
CR with Stud
Identification
The type, special construction features, and size are designated
by an identification code consisting of prefix letters followed by a
dash and suffix numbers.
The initial prefix letters denote the type of track roller/cam
follower. Additional prefix letters are used when it is necessary to
denote special construction features. The suffix numbers following
the prefix letters denote the size of the track roller. See Table 1.
The basic types are listed below:
CR - regular stud type, full complement needle rollers, inch series
YCR - yoke type, full complement needle rollers, inch series
Descriptions of typical examples, with complete letter codes
combining basic type of bearing and construction features follow.
See Table 2.
Since the entire identification code might not appear on the bearing
itself, the manufacturer’s parts list or another reliable source should
always be consulted when ordering bearings for field or service
replacement, to make certain that the correct unit with the correct
lubricant is specified.
•

Sealed Track Rollers – Inch Series
Inch series sealed track rollers contain a lip type seal and an internal
thrust washer. On some sizes of track rollers, the thrust washer and
seal have been incorporated into a single component. Regardless
of configuration, the thrust washer fits between the shoulders
of the outer ring and inside faces of the steel retaining washer
and flange of the stud. These washers reduce sliding friction
and serve to increase the life of the bearing, particularly when
it is infrequently relubricated or where misalignment occurs. In
all cases, the external dimensions of the sealed bearings are the
same as the unsealed bearings. The seals are thermally stable in
a temperature range between -25˚ F and +225˚ F.
profiled Track Rollers
These units are available with cylindrical or profiled outer
rings.
Track rollers are designed with a profiled outer ring to alleviate
the uneven bearing loading resulting from deflection, bending or
misalignment in mounting.
To specify a profiled ring for any inch series track roller having
a cylindrical outer ring, add the letter “C” at the end of the prefix
code. For example:
regular stud type, full complement of needle prefix CR –
rollers and cylindrical outer ring
prefix CRC – same as above, but with profiled outer ring.
The O.D. tolerance of profiled track rollers is +0.000 - 0.002 inch.
The profile radii are listed in Table 3.

Timken products listed on the following pages have been
designed with the outer ring of large radial cross section to
withstand heavy rolling and shock loads on track type or camcontrolled equipment.
Regular stud type (CR) are designed with integral studs for
cantilever mounting. When a regular stud type track roller is used
within the permissible dynamic load (Fr perm) given in the tabular
data, the ductile core of the stud provides the necessary toughness
for and resistance to shock loads. A screwdriver slot or a hexagonal
wrench socket in the head of the stud facilitates mounting.
Yoke type (YCR) are designed for straddle mounting. Each type
is available with a full complement of needle rollers.
All inch series track roller have a black-oxide finish on all
external surfaces.
NEEDLE Roller Bearings
Eccentric Studs
To provide radial adjustment of the outer ring toward the track
or cam surface at the time of installation, the regular inch series
stud types are available with eccentric studs which are specified
by adding the letter “E” to the construction feature code:
prefix CRSBE – regular stud type track roller with full complement of needle rollers, two seals, with internal thrust washers, hexagonal wrench socket in stud head, and eccentric stud.
Pertinent dimensions of the eccentric stud are listed in Table 5.

Since a track roller with an eccentric stud is usually adjusted upon
installation by turning the stud in the mounting hole, a close clearance
fit between the outside diameter of the bushing and the mounting hole
is necessary. For turning the stud, a hexagonal wrench is generally
more convenient than a screwdriver, and an option for a hexagonal
wrench socket in the head of the stud should be exercised.
Some applications may require more secure positioning than
provided by the tightened stud nut. If so, it is suggested that the housing
and eccentric bushing be drilled at the time of installation to accept
a locating dowel pin.
* To ensure proper clamping of the stud, the housing should be slightly wider

Load Ratings
When the outer ring of a stud type or yoke type track roller
runs on a track, the contact under a radial load causes elastic
(oval) deformation of the outer ring. As a result, a smaller zone of
the raceway is loaded and the load is distributed on fewer needle
rollers. This in turn affects the track roller’s dynamic and static load
ratings. Also, this deformation generates bending stress in the outer
ring which must not exceed the maximum permitted for the material
of the outer ring. The maximum permissible dynamic (Fr perm) radial
load condition is determined by this requirement.
The rating life of a stud type or yoke type track roller should
be calculated using the dynamic load ratings Cw shown in the
tables. The tables also show the maximum permissible radial
load, Fr perm that can be dynamically applied on the stud type
or yoke type track rollers. However, to calculate the L 10 life
of a track roller, the applied radial load must not be greater
than Cw /4 based on ideal operating conditions of alignment,
lubrication, temperature, speed and accelerations.
Stud Type and Yoke Type Track Rollers
In addition to the basic static load rating C0, the tables also list
the maximum permissible static radial load F0r perm that may be
applied to a stud type or yoke type track roller. The values of F0r perm
result in a minimum static factor fs of 0.7 for the worst condition of
internal load distribution in inch series track roller operation. The
F0r perm values must not be exceeded. The static factor fs can be
calculated using the following formula:
F0r perm
fs ≥ 0.7 •
P0r
where
F0r perm = Maximum permissible static radial load
P0r F0r
= Equivalent static load
P0r = F0r for yoke type track rollers

Mounting
The surface of the hole in the machine element, which supports
the stud or the mounting shaft, must not deform under the expected
load, and the support should be sufficiently rigid to resist bending
loads.
Deformation and bending will cause uneven loading of the
outer ring.
In mounting the stud type track roller, the retaining washer must
be firmly backed up by a flat shoulder which is square with the stud
center line. The shoulder diameter must be no smaller than the
minimum clamping diameter (da) listed in the tabular data.
The maximum inherent strength of the stud is obtained when
the unit is supported as close as possible to the retaining washer,
which minimizes the bending moment. For this reason, the edge
of the housing which supports the stud shank should be kept as
sharp as possible, but free from burrs.
To minimize deflection in mounted stud type track rollers, the
stud shank should be housed with the fit (db) shown in the tabular
data. The clamping nut should not be tightened with a torque value
higher than the maximum listed. A screwdriver slot or hexagonal
socket in the end of the stud is provided for a tool to prevent the
stud from turning when the nut is being tightened. Since the bottom
of the screwdriver slot is not flat, it is helpful to put a radius on the
tip of the screwdriver being used to hold the stud more securely.
When the stud shank is housed with an interference fit,
installation force should be applied only to the center portion of
the flanged end of the stud, preferably with an arbor press.
When the loads are high, the yoke type track rollers should be
mounted on a high strength bolt or shaft with the tight transition fit
listed in the tabular data. The bearing should be clamped between
flat and parallel faces at right angles to the axis to prevent the
retaining washers from coming off under load. If the bearing cannot
be clamped, a close axial fit in the yoke is required.
When the applied loads are light to moderate, the inner ring of
a yoke type track roller may be mounted on an unhardened shaft
or bolt with the loose transition fit listed in the tabular data. Again,
the retaining washers should be backed up axially to prevent their
coming off under load.

Lubrication
C
All inch series stud type track rollers with a screwdriver slot in
the flanged end of the stud have provisions for lubrication through
the flanged end of the stud. The 12 and larger sizes of inch series
stud type track rollers with screwdriver slots have provisions
for relubrication through either end of the stud and through a
cross-drilled hole in the shank. The ends of the axial holes are
counterbored to accept drive type grease lubrication fittings.
Hole diameters for these grease fittings are listed in the tables of
dimensions.
Sizes 8 through 10-1 of the inch series stud type track rollers
with a hexagonal socket in the flanged end of the stud cannot be
relubricated. Size 12 and up have relubrication provisions in the
threaded end of the stud and a cross-drilled hole in the shank. At the
threaded end of the stud, the axial hole is counterbored to receive
a drive type grease fitting. Sizes 12 through 22 and 48 through 64 of
inch series stud type track rollers with hexagonal sockets also have
provisions for relubrication through the hex socket in the flanged
end of the stud. Sizes 48 through 64 are supplied with lubrication
fittings which may be installed in the axial hole in the bottom of the
hexagonal slot in the head end of the stud, at a depth which allows
the hexagonal wrench to be inserted in the wrench socket without
damaging the grease fitting.
Plugs are furnished with stud type track rollers to close off
unused holes. If the cross-drilled hole in the stud shank is not used,
it will be covered when the track roller is installed properly.
Most inch series yoke type track rollers are produced with
lubrication holes and grooves in the inner ring bores so they can
be relubricated through axially and radially drilled holes in the
supporting shaft or bolt.
Oil is the preferred lubricant for all types. Use continuous
oil lubrication or frequent grease lubrication for steady rotating
conditions. Applications involving slow, intermittent oscillation
are not as critical, and longer intervals between relubrication are
permissible. Both stud and yoke type track rollers are normally
supplied with medium temperature grease lubrication.

Special Track Rollers/
Cam Followers
Track rollers can be obtained with dimensions different from
those in the tabular data, if the quantities permit economical
production. For these and other modifications please consult your
Timken representative.
Stud Type and Yoke Type Track Rollers
Forklift Truck
Yoke type sealed units serve as high capacity and rugged guide
rollers for lift trucks. Their design permits them to be mounted on
studs welded to the structure. The seals exclude foreign matter
and extend the time between relubrication periods.
Hay Baler
Stud types are important components on many different types
of farm equipment because of their required long service life under
punishing loads and severe operating conditions. Needle bearings
provide dependable and economical operation in the windrow
pickup of hay balers.
CA
Machine Way
Heavily loaded machine tool tables must travel freely and
accurately. Stud and yoke type sealed units, in combination, support
and guide such tables under the most severe conditions. The high
capacity and the very low wear rate permit heavy loads to be
carried without impairing the accuracy of the table’s travel. The
seals exclude dirt and chips and make the need for relubrication
infrequent.
Reciprocating Slide
Stud types find wide application in feeding and advancing
mechanisms on metalworking presses. The rotary motion of an
eccentric cam rotating between two cam followers mounted on a
slide imparts reciprocating linear motion to the slide. Dwell periods
as well as accuracy in both rapid and slow linear actuation of the
slide are made possible.

Seals help retain lubricant and exclude foreign matter
(CRS Series).
Hexagonal wrench socket in stud head for mounting
Relubrication via axially drilled hole through stud with
cross-drilled holes in stud raceway and shank.
Recessed axial hole accepts standard nominal inch
drive-type grease lubrication fitting.
Lubrication fitting plugs furnished to close off unused holes.
• Tolerance limits for outside diameters of stud and outer ring
refer to “single mean diameter” (see engineering section).
• A close fit between stud and hole required for mounting.
• Bore dimensions given below result in varying fit (0.0010 in.
tight to 0.0005 in. loose).
• Retaining washer should be firmly backed up by flat housing
shoulder (perpendicular to the stud axis).
• Shoulder diameter should be at least same size as minimum
clamping diameter listed.
• May be mounted with two thin lock nuts or nut and lock
washer.

Seals help retain lubricant and exclude foreign matter
(CRS Series).
Hexagonal wrench socket in stud head for mounting
Relubrication via axially drilled hole through stud with
cross-drilled holes in stud raceway and shank.
Recessed axial hole accepts standard nominal inch
drive-type grease lubrication fitting.
Lubrication fitting plugs furnished to close off unused holes.
• Tolerance limits for outside diameters of stud and outer ring
refer to “single mean diameter” (see engineering section).
• A close fit between stud and hole required for mounting.
• Bore dimensions given below result in varying fit (0.0010 in.
tight to 0.0005 in. loose).
• Retaining washer should be firmly backed up by flat housing
shoulder (perpendicular to the stud axis).
• Shoulder diameter should be at least same size as minimum
clamping diameter listed.
• May be mounted with two thin lock nuts or nut and lock

NEEDLE Roller Bearings
YOKE Type Track Rollers
YCR, YCRS Series
Inch Series
• A close fit between stud and hole required for mounting bore
• Non-separable unit with outer ring, a full complement of
•
C
•
•
needle rollers, inner ring, self-lubricating resin internal thrust
washers, and two retaining washers securely fastened to the
inner ring.
Seals in counterbores of outer ring seal against the retaining
washers; retain lubricant and exclude foreign matter (YCRS
Series).
Dimensions shown are for unplated finished unit.
Tolerance limits for outside diameters of stud and outer ring
refer to “single mean diameter” (see engineering section).
•
•
•
dimensions given below result in varying fit (0.0010” tight to
0.0005” loose).
Machine element must be sufficicently rigid in area of
mounting bolt holes to resist local crushing under the applied
load and resist bending causing uneven loading of rollers.
Unit should be clamped endwise between parallel faces
(perpendicular to axis) to prevent retaining washers from
coming off under load.
If the unit cannot be clamped, yoke requires a close axial fit.

Needle Roller Thrust Bearings, Assemblies, Washers
THRUST BEARINGS, ASSEMBLIES, WASHERS
Overview: Needle roller and cage thrust assemblies are complements of small diameter needle rollers
arranged in a spoke-like configuration. Needle rollers are equally spaced by means of a cage whose
web section separates the rollers and provides guidance to keep them tracking in an orbital path. The
purpose of these assemblies is to transmit a thrust load between two relatively rotating objects while
greatly reducing friction.
Needle roller and cage thrust assemblies can also be unitized with lipped washers which service as
raceway surfaces for the needle rollers. Washers can be supplied separately or can be mechanically
unitized to the needle roller thrust assemblies for ease of handling.

The needle roller and cage thrust assembly (Series FNT) has
a two piece steel cage and through hardened needle rollers
which are precision finished to close tolerances for optimum load
distribution. The cage is comprised of two mating pieces that are
securely fastened together.
Series AXK needle roller and cage thrust assembly, which can
be used interchangeably with the FNT assembly, has a one piece
cage. The cage is similar in design to the successful profiled radial
steel cages.
These cage assemblies have a very thin section and when
they must run directly against the back up surface raceways their
section may be 2 to 5 mm (0.08 to 0.20 in.) which is equivalent to
the diameter of the needle rollers used.
When the back up surfaces cannot be hardened and ground,
hardened washers of different thicknesses are available.

Thrust bearing assemblies of the FNTK, FNTF and FNTKF Series
have been specially designed for use in applications where a
unitized assembly allows for ease of installation and eliminates
the need for heat treatment and precision finishing of one or both
thrust bearing backup surfaces.
Each FNTK, FNTF or FNTKF assembly consists of a FNT needle
roller and cage thrust assembly with one or two special lipped
washers that snap over the cage to produce a unitized thrust
bearing assembly. The FNTK and FNTF assembly has one such
washer, the FNTKF assembly has a washer on each side of the
bearing.
The backup surfaces for these unitized thrust bearing
assemblies should meet the limits of permissible out-of-squareness
and coning or dishing as shown in figures 1 and 2 on C232. Oil is
the preferred lubricant for these assemblies, however they are
also available pregreased for applications that do not allow for
oil lubrication.

Thrust Washers
Ideally, a thrust washer should be stationary with respect to,
and piloted by, its supporting or backing member, whether or not
this is an integral part of the shaft or housing. There should be no
rubbing action between the thrust washer and any other machine
member. Some thrust washers are designed for bore piloting others
may be piloted by their outside diameter.
Thin Thrust Washers (AS)
The metric series thin thrust washers are made of hardened
spring steel. They may be out of flat due to heat treatment, but will
flatten under load. Thin washers are used when the supporting or
backing members cannot be adequately prepared as raceways
for the needle rollers. These washers are only 1 mm (0.04 in.)
thick (dimensions) and provide a very compact and cost-effective
bearing arrangement. Although they are usually guided on the shaft,
they may be housing-guided when required by application.
Heavy Thrust Washers (LS)
These metric series thrust washers are made of bearing
quality steel, hardened and precision ground on the flat raceway
surfaces. Their bores and outside diameters are not ground but
provide satisfactory surfaces for shaft piloting or housing piloting
arrangements.
Shaft Piloted Washers (WS.811) And
Housing Piloted Washers (GS.811)
These shaft piloted and housing piloted metric series thrust
washers are primarily for use with metric series cylindrical roller
thrust bearings of Series 811. They are made of bearing quality
steel with, hardened and precision ground and lapped flat raceway
surfaces. The tolerances of the thrust bearing bore and outside
diameter shown in the engineering section apply to shaft and
housing piloted washers.
CA
Thin (CP) and thick (CPR) thrust washers
The washer incorporated in the AX Series thrust bearing is made
from hardened bearing steel and forms one of the reaceways for
the rolling elements. The opposing raceway is generally provided
by a separate thrust washer of similar design supplied by Timken.
When the AX Series thrust bearing is piloted by the revolving part,
the thrust washer must be piloted by the stationary part and vice
versa. If the revolving part and the stationary part are noticeably
eccentric to each other, the thrust bearing with integral washer
must, without exception, be piloted by the revolving part.
The second raceway for the rolling elements may also be formed
by the face of a shoulder or an inserted washer, provided these
have the correct hardness and geometric dimensions.

The rolling elements of the AX Series thrust bearings are
retained and guided in radial pockets within the cage. The cage
is retained in relation to the thrust washer by means of a retaining
cap. The design of a one-piece steel cage employs a special
curvature that guides the rolling elements by their ends along
their centerlines.
In addition, this special curvature gives the steel cage great
rigidity while providing maximum lubricant space. This unitized
assembly of components facilitates installation and provides a high
axial load capacity while occupying only minimal space. Note that
the AX Series is not interchangeable with the AXK Series or FNT
Series needle roller and cage thrust assemblies.
Standard AX Series needle thrust bearings combined with a
thick washer provide rotational accuracy and axial run-out to Class
6 levels according to ISO Standard 199 for ball thrust bearings.
They can be supplied in High Precision “HP” quality, providing a
precision grade above Class 5. AX Series needle thrust bearings
with a thin washer are of minimal thickness and provide excellent
economy. They should be considered whenever the degree of
support and rotational accuracy requirement allow.

If an inspection of the bore diameter is desired, the bore
diameter (Dc1) of the assembly should be checked with “go”
and “no go” plug gages. The “go” plug gage size is the minimum
bore diameter of the assembly. The “no go” plug gage size is the
maximum bore diameter of the assembly.
The assembly, under its own weight, must fall freely from the
“go” plug gage. The “no go” plug gage must not enter the bore.
Where the “no go” plug gage can be forced through the bore, the
assembly must not fall from the gage under its own weight.
Tolerances For Thrust Washers
Tolerances for the bore diameters of series WS, shaft piloted
thrust washers are given in the engineering section. Tolerances for
the outside diameters of Series GS, housing piloted thrust washers
are given in the engineering section.
Tolerances for the outside and bore diameters of Series AS
thrust washers are given in Table 2. Thickness tolerance for Series
AS thrust washers is +0.05 mm (±0.002 in.).
Bore Inspection Procedure for Series AS and
LS Thrust Washers
If an inspection of the thrust washer bore diameter (d) is
desired, it should be checked with “go” and “no go” plug gages.
The “go” plug gage size is the minimum bore diameter of the thrust
washer. The “no go” plug gage size is the maximum bore diameter
of the thrust washer.
The thrust washer, under its own weight, must fall freely from
the “go” plug gage. The “no go” plug gage must not enter the bore.
Where the “no go” plug gage can be forced through the bore, the
thrust washer must not fall from the gage under its own weight.

NEEDLE Roller Bearings
Mounting Tolerances
Needle Roller and Cage Thrust Assemblies –
Metric Series
On FNT and AXK Series needle roller and cage thrust
assemblies, the cage bore has a closer tolerance than the outside
diameter, therefore bore piloting is preferred for these assemblies.
To reduce wear it is suggested that the piloting surface for the cage
be hardened to an equivalent of at least 55 HRC. Where design
requirements prevent bore piloting, the FNT or AXK Series needle
roller and cage thrust assemblies may be piloted on the outside
diameters. For such cases, suitable O.D. piloting dimensions should
be determined. Mounting tolerances are given in Table 4.
C
Thrust Washers
The mounting tolerances for series AS, LS, WS and GS thrust
washers for use with needle roller and cage thrust assemblies
are given in Table 4.
As for the FNT and AXK Series thrust assemblies, to reduce
wear, the piloting surface for the thrust washers should also be
hardened to an equivalent of at least 55 HRC.
Back Up Surfaces
In some applications, it is desirable to use the back up surfaces
as raceways for the needle rollers of the needle roller and cage
thrust assemblies. In such designs these surfaces should be parallel
and must be hardened to at least 58 HRC. If this hardness cannot
be achieved, and thrust washers cannot be used, the load ratings
must be reduced, as explained in the engineering section.
Thrust raceway surfaces must be ground to a surface finish of
0.2 µm Ra (79 µin Ra). When this requirement cannot be met, thrust
washers must be used.
The raceways against which the needle rollers operate, or the
surface against which the thrust washers bear must be square
with the axis of the shaft. Equally important, the raceway, or
surface backing the thrust washer, must not be dished or coned.
The permissible limits of out-of-squareness and dishing or coning
are shown in Figures 1 and 2.
Raceway contact dimensions Ea and Eb are given in the tabular
pages. For the thin series AS thrust washers, full back up between
the dimensions Ea and Eb should be provided.
For AX Series thrust bearings, the maximum out of square must
be of no more than 0.0005 mm (maximum angle no more than 1 min.
43 sec.), see Figure 1.
Thin series needle thrust bearings and thin thrust washers
must be supported on a flat, rigid, and continuous face throughout
the area of circulation of the needles bounded by dimensions Eb
and Ea.
Thick series needle thrust bearings and thick thrust washers
can be supported on a more restricted or discontinuous shoulder,
provided that the deflection of the washer under load does not
impede the smooth operation of the thrust bearing or the required
axial run-out.
When an application does not involve the use of a thrust washer,
the surface forming the second raceway must:
• extend at least across the whole area of circulation of the
rolling elements between dimensions Eb and Ea, and,
• posess a suitable surface finish (≤ 0.2 µm Ra or ≤ 79 µin Ra)
and sufficient hardness in relation to the load to be supported.
A hardness of 58 HRC (min.) enables thrust bearings to carry
their full load capacity. Lower hardness values reduce the
capacities shown in the tables of dimensions (see tabulated
sizes).
Tolerances for Piloting Surfaces (AX Series)
• Piloting on the shaft : h10 on dimensions Dc1 for thrust
bearings or dimension d for thrust washers.
• Piloting in the housing : H10 on dimensions D for thrust
bearings or dimension d1 for thrust washers.

Needle Roller Thrust Bearings, Assemblies, Washers
Load Ratings
Slippage can occur if the applied axial load is too light and the
operating speed of the needle roller and cage thrust assembly is
high, particularly if accompanied by inadequate lubrication. For
satisfactory operation, a certain minimum load must be applied to
a needle roller and cage thrust assembly which can be calculated
from:
Fa min = C0/2200 [kN]
where
C0
Fa min
- static load rating [kN]
- minimum axial load [kN]
Coefficient of Friction
In general, the coefficient of friction of a thrust bearing
(consisting of a needle roller and cage thrust assembly and thrust
washers) is defined as the friction torque divided by the product
of the applied load and the bearing pitch radius. This coefficient
of friction is not a constant value but will vary considerably with
load, speed and lubricant. Generally the coefficient of friction
becomes smaller as the load is increased and larger as the speed
is increased. It is suggested that a value of 0.003 to 0.004 be used
for needle thrust bearings and 0.004 to 0.005 be used for roller thrust
bearings as a conservative estimate.
Lubrication
Oil is the preferred lubricant for needle roller and cage thrust
assemblies and an ample oil flow is absolutely necessary for high
speeds, or for moderate speeds when the load is relatively high.
When the application must utilize grease lubrication the needle
roller and cage thrust assembly should be ordered pregreased.
When the speeds are low, and rotation is not continuous, the initial
charge of grease may be suitable for the life of the application.
When the speeds are moderate, however, the designer must
provide for frequent regreasing. Since the needle rollers tend to
expel the lubricant radially outward, relubrication passages should
be directed to the bore of the cage whether oil or grease is used
as the lubricant.
Special Designs
Needle roller and cage thrust assemblies and thrust washers
are also made to special dimensions and configurations, as well
as from special materials, when quantities permit economical
manufacture.
Needle roller and cage thrust assemblies are particularly
adaptable to low cost integral combination with special thrust
washers. When the use of such special designs is considered, the
following pages should be reviewed for evaluation of proposed
arrangements.
TYPE AXJ BEARINGS
Needle thrust bearings type AXJ have been developed by
Timken to run at very high rotational speed. They comprise two rows
of needles retained and guided in hardened steel cages. These
assemblies are retained on either side of a common washer by
inserted retaining caps which serve to center them with adequate
clearance in relation to the washer.
The special feature of these thrust bearings is the self-piloting
action to which each rotating ring of needles is submitted. This
self-piloting is transmitted to the washer which is “floating” in
relation to the shaft. For this reason, the relative speed of each
ring of needles relative to its raceway and the speed of the washer
relative to the rotating shaft are reduced by about half.
With a well-designed oil circulation, type AXJ thrust bearings
permit speeds approximately twice that achieved with nomal
thrust bearings.
To ensure the axial position of a shaft in both directions, two AXJ
thrust bearings should be mounted on either side of an intermediate
washer with oil hole (type PMH), piloted in the housing. Please
consult your Timken representative for applications involving the
use of these special thrust bearings.

Reference standards are:
Cylindrical roller thrust bearings provide rolling bearing
arrangements which can accommodate high dynamic axial
loads as well as shock loads. The simple geometry of the bearing
components allows the use of many design arrangements. As an
example, for less demanding applications it is possible to combine
E a cylindrical
E a roller and cage thrust assemblies with
metric series
the metric series heavy thrust washers (LS,CPR) and even metric
ra thin thrust
ra washers (AS, CP). These two thrust washer
b series
types
are more
commonly used with needle roller and cage thrust
assemblies. Cylindrical roller and cage thrust assemblies can also
be used without bearing thrust washers if the adjacent machine
components can be prepared to serve as suitable raceways.
Cylindrical roller thrust bearings may be used where the load
carrying capability of needle roller and cage thrust assemblies is
rainsufficient. Also the bearings can accommodate high dynamic
and static axial loads in one direction but they are not suitable to
transmit radial loads.

Needle Roller Thrust Bearings, Assemblies, Washers
Construction
Bearing Thrust Washers
Basic Designs
Shaft Washers And Housing Washers
Thrust Bearings with Two Thrust Washers
Heavy Thrust Washers (LS), Thin Thrust
Washers (AS)
Thrust bearing type AXZ and ARZ each have two thrust washers
retained by an integral cap, giving protection against the entry of
dirt and metal particles while helping to retain the lubricant.
Cage designs
Metric series 811 and 812 cylindrical roller thrust bearings use
molded cages of glass fiber reinforced nylon 6/6 (suffix TVP), or
machined cages of light metal (suffix LPB). The cages are designed
to be piloted on the shaft. The reinforced nylon cages can be used
at temperatures up to 120° C (250˚ F) continuously for extended
periods. When lubricating these bearings with oil it should be
ensured that the oil does not contain additives detrimental to the
cage over extended life at operating temperatures higher than
100° C (212˚ F). Also, care should be exercised that oil change
intervals are observed as old oil may reduce cage life at such
temperatures.
The rolling elements of the AR Series thrust bearings are
retained and guided in radial pockets within the cage. The cage
is retained in relation to the thrust washer by means of a retaining
cap. The design of a one-piece steel cage employs a special
curvature that guides the rolling elements by their ends along
their centerlines.
In addition, this special curvature gives the steel cage great
rigidity while providing maximum lubricant space. This unitized
assembly of components facilitates installation and provides a high
axial load capacity while occupying only minimal space.
AR Series needle thrust bearings with a thin washer are of
minimal thickness and provide excellent economy. They should
be considered whenever the degree of support and rotational
accuracy requirement allow.
Shaft washers of types WS.811 and WS.812 as well as housing
washers of types GS.811 and GS.812 are components of the metric
series cylindrical roller thrust bearings of series 811 and 812. They
are made of bearing quality steel, with hardened and precision
ground and lapped flat raceway surfaces. The tolerances of the
thrust bearing bore and outside diameter shown in the engineering
section apply to shaft and housing piloted metric series washers.
These thrust washers, more frequently used with needle roller
and cage thrust assemblies of metric series FNT or AXK, are
also suitable for use with the cylindrical roller and cage thrust
assemblies K.811. The heavy thrust washer of series LS are made
of bearing quality steel, hardened and precision ground on the flat
raceway surfaces. The bore and outside diameters of the heavy
thrust washers are not ground, therefore, when used with K.811 type
assemblies they are only suggested where accurate centering is
not required. The thin thrust washers of series AS may be used in
applications where the loads are light. Both types of these washers
are listed in the tabular part of the metric series needle roller and
cage thrust assemblies section.
CA
Thin (CP) and thick (CPR) thrust washers
The washer incorporated in the AR Series thrust bearing is made
from hardened bearing steel and forms one of the raceways for
the rolling elements. The opposing raceway is generally provided
by a separate thrust washer of similar design supplied by Timken.
When the AR Series thrust bearing is piloted by the revolving part,
the thrust washer must be piloted by the stationary part and vice
versa. If the revolving part and the stationary part are noticeably
eccentric to each other, the thrust bearing with integral washer
must, without exception, be piloted by the revolving part.
The second raceway for the rolling elements may also be formed
by the face of a shoulder or an inserted washer, provided these
have the correct hardness and geometrical dimensions.

Cylindrical roller thrust bearings of dimension Series 811 and
812 comprise of a cylindrical roller and cage thrust assembly (K), a
shaft washer (WS) and a housing washer (GS). Providing the back
up surfaces can be hardened and ground they can be used as
raceways for the cylindrical rollers of the cylindrical roller and cage
thrust assembly, resulting in a compact bearing arrangement.
Series AR are available with thin or thick CP washers or heavy
CPR thrust washers.

Mounting Tolerances
Shaft and housing tolerances for mounting metric series
cylindrical roller and cage thrust assemblies are given in Table 4
shown below. If the cylindrical rollers of the cylindrical roller and
cage thrust assemblies are to run directly on the adjacent support
surfaces, these must be hardened to at least 58 HRC. Raceway
contact dimensions Ea and Eb must be observed.

Bearing thrust washers should make close contact with the
shaft or housing shoulder and must not touch the fillet radius.
Therefore the maximum fillet radius ras max must be no greater
than the minimum chamfer rs min of the shaft washer (WS) and the
housing washer (GS). See tabular page C255.
Since roller thrust bearings generally run under considerable
loads, their incorporated washer (and thrust washer) should be
supported on a shoulder covering the whole area of circulation of
the rollers bounded by dimensions Eb and Ea.
Load Ratings
Minimum Axial Load
To prevent slippage a cylindrical roller thrust bearing must
always be axially loaded. For satisfactory operation a certain
minimum load must be applied between the cylindrical rollers and
their raceways. This can be calculated from:

The backup surfaces for the shaft washers WS.811 and WS.812
as well as the housing washers GS.811 and GS.812 of cylindrical
roller thrust bearings must be square with the axis of the shaft.
Equally important, the raceway or the surface backing the thrust
washer, must not be dished or coned. The permissible limits of
the squareness and dishing or coning are shown in figures 1 and
2. When using the thin (AS) thrust washers the cylindrical rollers
of the thrust cage assembly must be supported over their entire
length.

Needle Roller Thrust Bearings, Assemblies, Washers
Identification
NTA is the complete prefix code for a needle roller and cage
thrust assembly with inch nominal dimensions using needle rollers
of the smallest practical diameter.
Cylindrical roller and cage thrust assemblies with inch nominal
dimensions are identified by the prefix letters NTH. They use large
diameter cylindrical rollers providing higher load ratings.
Thrust washers of inch nominal dimensions are identified by the
prefix letters TR, followed by another letter such as A, B, or C etc.
indicating washer thickness. TRA is the complete prefix code for
the thinnest thrust washer made to inch nominal dimensions.
Most thrust washers are intended to be piloted on their bores.
Some washers, however, are designed to be piloted on their outside
diameters. Such washers are identified by the letter D following
the thickness code letter. Thus TRJD is the complete prefix code
for a thrust washer with inch nominal dimensions of J thickness
and designed to be piloted by its outside diameter.
Cylindrical roller thrust bearings with prefix code NTHA are
made up of one NTH assembly, one TRI or TRJ bore piloted washer
and one TRID or TRJD outside diameter piloted washer.
Since the bearing designation for thrust assemblies does
not appear on the bearing itself, the manufacturer’s parts list or
another reliable source should always be consulted when ordering
bearings for service or field replacement, to make certain that the
correct bearing with the correct lubricant is used.
Construction
Needle roller and cage thrust assemblies (NTA) and cylindrical
roller and cage thrust assemblies (NTH) have hardened cages and
through hardened, precision ground rollers. The cages are securely
fastened assemblies of two mating pieces. This construction
minimizes cage stress and assures that the roller retaining function
of the cage is unaffected by normal wear. The needle rollers and
the cylindrical rollers are precision ground and lapped to close
tolerance for optimum load distribution.
Thrust washers for the needle roller and cage thrust assemblies
are designed for bore piloting. The thinner thrust washers are
tumble burnished and may be out of flat due to heat treatment,
but will flatten under load. The raceway surfaces of thick thrust
washers are ground and lapped.
Thrust washers for the cylindrical roller and cage thrust
assemblies are available in both bore piloted and outside diameter
piloted types. Their piloting surfaces are ground and raceway
surfaces are ground and lapped.

Bore Inspection Procedure for Assembly
The bore diameter (Dc1) of the assembly should be checked
with “go” and “no go” plug gages. The “go” plug gage size is the
minimum bore diameter of the assembly. The “no go” plug gage
size is the maximum bore diameter of the assembly.
The assembly, under its own free weight, must fall freely from
the “go” plug gage. The “no go” plug gage must not enter the bore.
Where the “no go” plug gage can be forced through the bore, the
assembly must not fall from the gage under its own weight.
Tolerances For Thrust Washers
Tolerances for the outside diameters and bore diameters of

The tolerances for inch series cylindrical roller thrust
bearings, cylindrical roller cage and thrust assemblies and their
corresponding component thrust washers appear in the tabular
data.
Mounting Tolerances
Needle Roller And Cage Thrust Assemblies
On NTA inch type needle roller and cage thrust assemblies the
cage bore has a larger contact area and a closer tolerance than
the outside diameter. Therefore, bore piloting is preferred for these
assemblies. To reduce wear it is suggested that the piloting surface
for the cage be hardened to an equivalent of at least 55 HRC.
Where design requirements prevent bore piloting, the NTA
needle roller and cage thrust assemblies may be piloted on
the outside diameters. It should be noted that the “diameter to
clear washer O.D.” given in the tabular data is not suitable for
outside diameter piloting. For such cases suitable O.D. piloting
dimensions should be determined in consultation with your Timken
representative.
Thrust Washers For Use With NTA Needle
Roller And Cage Thrust Assemblies
Ideally, a thrust washer should be stationary with respect to,
and piloted by, its supporting or backing member, whether or not
this is an integral part of the shaft or housing. There should be no
rubbing action between the thrust washer and any other machine
member. The economics of design, however, often preclude these
ideal conditions and thrust washers must be employed in another
manner. In such cases design details should be determined in
consultation with your Timken representative.
Cylindrical Roller and Cage Thrust
Assemblies
Type NTH assembly cage has a relatively large contact area
on both the bore and the outside diameter. Thus these assemblies
can be piloted by either the shaft or the housing. To reduce wear
it is suggested that the piloting surface for the cage be hardened
to an equivalent of at least 55 HRC.
When the shaft is used as the piloting surface, the outside
diameter of the cage must clear the housing under all conditions.
Conversely, when the housing is the piloting surface, the shaft must
clear the cage bore under all conditions. It will be noted that the
mounting dimensions are given in the tabular data for both shaft
and housing piloting. Bore inspection procedure for the assembly
given on page C267 should be used for checking the bore of NTH
assemblies.
Thrust Washers For Use With Cylindrical
Roller And Cage Thrust Assemblies
Types TRID and TRJD thrust washers for use with cylindrical
roller and cage thrust assemblies are designed to pilot from the
housing and to clear the shaft. Types TRI and TRJ thrust washers
are designed to pilot from the shaft and clear the housing. The
thrust washers should be stationary with respect to their piloting
(or locating) machine members. There should be no rubbing
action between the washer and any other machine member.
Backup Surfaces
In some applications it is desirable to use the back up surfaces
as raceways for the rollers of the thrust assemblies. When this is
done, these surfaces must be hardened to an equivalent of at least
58 HRC. If this hardness cannot be achieved and thrust washers
cannot be used, the load ratings must be reduced as explained in
the engineering section of this catalog.
Thrust raceway surfaces must be ground to a surface of 8
µin Ra (0.20 µm Ra). When this requirement cannot be met, thrust
washers must be used.
The raceways against which the rollers operate, or the surfaces
against which the thrust washers bear, must be square with the
axis of the shaft. Equally important, the raceway, or surface backing
the thrust washer, must not be dished or coned. The permissible
limits of out-of-squareness and dishing or coning are shown in
figures below.

Type NTHA Cylindrical Roller Thrust Bearing
The NTHA cylindrical roller thrust bearing consists of the NTH
cylindrical roller and cage thrust assembly and two thrust washers.
This bearing is sold as a unit.
A typical mounting of the thrust bearing when the shaft rotates
is shown in Figure a. The bore of the rotating, shaft supported thrust
washer is ground for an accurate fit on the shaft. The outside
diameter of the stationary, housing supported thrust washer is
ground for a proper fit in the housing.
The NTHA cylindrical roller thrust bearing cage is normally
shaft piloted. In the event it is necessary to pilot the cage by the
housing, Figure b illustrates a possible mounting arrangement.
When other mounting arrangements are dictated by the application
they should be determined in consultation with your Timken
representative.
Load Ratings
Minimum Axial Load
Slippage can occur if the applied axial load is too light and the
operating speed of the needle roller and cage thrust assembly is
high, particularly if accompanied by inadequate lubrication. For
satisfactory operation a certain minimum load must be applied to
a needle roller and cage thrust assembly which can be calculated
from:
Famin = C0/2200 [lbf]
where
C0 – static load rating [lbf]
Famin – minimum axial load [lbf]
CA
Coefficient Of Friction
In general, the coefficient of friction of a thrust bearing
(consisting of a needle roller or a cylindrical roller and cage thrust
assembly and thrust washers) is defined as the friction torque
divided by the product of the applied load and the bearing pitch
radius. This coefficient of friction is not a constant value, but will
vary considerably with load, speed and lubricant. Generally, the
coefficient of friction becomes smaller as the load is increased
and larger as the speed is increased. It is suggested that a value
of 0.004 to 0.005 be used as a conservative estimate.
Figure a
Figure 4
Figure b
Lubrication
Oil is the preferred lubricant for needle roller or cylindrical roller
and cage thrust assemblies and an ample oil flow is absolutely
necessary for high speeds, or for moderate speeds when the load
is relatively high.
When the application must utilize grease lubrication the needle
roller and cage thrust assembly should be ordered pregreased.
When the speeds are low and rotation is not continuous, the initial
charge of grease may be suitable for the life of the application.
When the speeds are moderate, however, the designer must
provide for frequent regreasing. Since the rollers tend to expel
the lubricant radially outward, relubrication passages should be
directed to the bore of the cage whether oil or grease is used as
the lubricant.
Special Designs
Needle roller and cage thrust assemblies and thrust washers
are also made to special dimensions and configurations, as well
as from special materials, when quantities permit economical
manufacture.
Needle roller and cage thrust assemblies are particularly
adaptable to low cost integral combinations with special thrust
washers. When the use of such special designs are considered,
the following pages should be reviewed for evaluation of proposed
arrangements.

• Check for availability.
• The NTHA thrust cylindrical roller bearing consists of an NTH
d1
cage and roller assembly, one bore piloted washer and one
O.D. piloted washer. The NTHA bearing is identified and sold as
a unit, and is manufactured to inch nominal dimensions only.
Load ratings given are identical to the corresponding NTH
thrust cylindrical roller and cage assembly.
It is suggested that the cage and roller assembly
be bore piloted when applying NTHA bearings. When different
arrangements of piloting are required, please contact your
Timken representative.
Back-up sufaces should be flat and square with the center
line of the shaft.
To order individual thrust washers see washer designation
below.

Timken®
Reference standards are:
Torrington®
combined bearings consist of a radial
bearing (needle roller bearing) and a thrust bearing (roller or
needle bearing). The thrust roller bearing is usually a cylindrical
roller thrust bearing.
Combined bearings make an effective alternative in place of
two separate bearings in terms of cost, handling and packaging.
Combined bearings are possible to use with or without matching
inner rings and thrust washers, though these are listed opposite
the bearing part numbers, where possible, in the following pages
of tables, for convenience.

Construction
•
A
Needle roller – cylindrical roller thrust bearings of series NAXR
and RAXZ 500 are available with dust caps. They have the highest
axial load carrying capability of all combined bearings.
Combined bearings of series RAX 700 use a thin, one-piece outer
ring design similar in construction to metric drawn cups. The RAX
700 Series is available with an open or closed (RAXF) design, as
are standard drawn cups. These bearings use needle rollers for
both their radial and thrust complements.
The RAX 400 Series uses needle rollers for both their radial
and thrust complements, as with the RAX 700 Series, but are
constructed from two separate machined rings joined with a strong
metal insert. The RAX 500 Series, fabricated like the 400 Series,
uses heavier cylindrical rollers for their thrust complement. Both
series are available with matching thrust washers and inner rings
and should be considered for applications requiring higher load
capacity and running accuracy.
C288
TIMKEN PRODUCTS CATALOG
Each of the previous two bearing types may be best used
without inner rings because the radial internal clearances are
smaller if the needle roller and cage assemblies operate directly
on a hardened and ground shaft. Tolerance class F6 is the normal
specification for the needle roller complement bore diameters of
the unmounted bearings.
RAX 400 and 500 Series (without inner rings) can be supplied
with a smaller radial clearance if desired. Refer to the suffix options
TB and TC as listed in the chart above.
Quality requirements for shafts when used as a bearing
raceway are given in the engineering section of this catalog.
When it becomes impractical to meet the shaft raceway design
requirements, standard inner rings may be used with these
bearings.
Combined Needle Roller Bearings
DIMENSIONAL ACCURACY
Lubrication
Tolerances
When the applied axial loads are relatively high and the
application allows the use of oil as the desired method of
lubrication, bearing types NAXR and NAXK should be given
consideration. Combined bearings with a dust cap may use oil
lubrication although their design makes them better suited for use
with grease lubrication.
Combined bearings are typically shipped protected with a
corrosion-preventive compound which is not a lubricant. The
bearings may be used in oil or grease lubricated applications
without removal of the corrosion preventive compound, although
to avoid subsequent recognition problems it may be advisable to
remove the corrosion preventive compound before packing the
bearings with a suitable grease.
Metric series combined bearings (except Series RAX 700) are
manufactured to the normal tolerances which apply to the metric
series radial bearings and standard thrust bearings as shown in
the engineering section. The only exceptions are: the diameter
tolerances of the shaft piloted washer and the bearing width
tolerances shown in cross-sectional views listed on the tables in
the pages provided.
Because of the nature of the RAX 700 Series design, these
bearings must be inspected with suitable plug (GO and NO GO)
and ring gages corresponding to metric drawn cups of equivalent
bore and O.D. sizes.
The matching thrust washer thickness tolerances may be found
in the metric unitized thrust bearing section of this catalog.
BEARING MOUNTING
LOAD RATINGS
Mounting dimensions
Minimum axial load for combined bearings excluding RAX700:
Simple, through-bored housings are adequate for combined
bearings. The mounting tolerances for the mechanical ring
combined bearings are provided in Table 1.
The shaft piloted washers of combined bearings must be
supported at least over half their width. Other quality requirements
for shafts and housings are given in the engineering section of this
catalog. Requirements for fillets, recesses and shoulder heights
are the same as for needle roller bearings as shown in “Mounting
dimensions” paragraph on pages C102-C103.
When mounting these bearings in their housings with a tight fit,
relatively high press-in forces will be required which may brinell
the raceways of the thrust bearing arrangements. Particular care
should be exercised when installing needle roller - cylindrical roller
thrust bearings with dust caps and where the roller assembly of the
thrust bearings cannot be removed. In order to avoid brinelling of
the thrust bearing raceways the bearings should be installed with
uniform, continuous pressure against the installation tool, avoiding
sudden impact forces. At times it may even be desirable to heat
the housing before bearing mounting.

Drawn Cup Roller Clutches
A
drawn cup roller clutches
Overview: Drawn cup needle roller clutches are similar to drawn cup needle bearings in design,
but allow free rotation in only one direction while transmitting torque in the opposite direction.
These designs use the same small radial section as drawn cup needle roller bearings and are
offered as clutch-only units or as clutch and bearing assemblies.
A
• Sizes: 3 mm - 35 mm bore (1/8 in. - 1.4 in.) bore.
• Markets: Office equipment, paper-towel dispensers, exercise equipment,
appliances and two-speed gearboxes.
CA
• Features: Compact, lightweight and operate directly on a hardened shaft.
• Benefits: Installation is easily accomplished with a simple press fit.

The
drawn cup roller clutch transmits
torque between shaft and housing in one direction and allows free
overrun in the opposite direction. When transmitting torque, either
the shaft or the housing can be the input member. Applications are
generally described as indexing, backstopping or overrunning.

Identification
The prefix letters in the designation of the Timken Torrington
drawn cup roller clutches and drawn cup roller clutch and bearing
assemblies denote whether these are manufactured to metric or
inch nominal dimensions. Designation codes for clutches and
clutch and bearing assemblies with metric nominal dimensions
begin with the letter “F”. Designation codes for clutches and clutch
and bearing assemblies with inch nominal dimensions begin with
the letter “R”.
The basic types of clutches and clutch and bearing assemblies
are listed below:

Clutch And Bearing Assembly
Types FC, FC-K, FCS, FCL-K, RC and RC-FS are of clutch-only
configurations for use with external radial support (usually two
drawn cup needle roller bearings). Separate bearings position
the shaft and housing concentrically and carry the radial load
during overrun.
In the lock mode shown in the drawings below, the relative
rotation between the housed clutch and the shaft is opposite to
that in the overrun mode. The rollers, assisted by the leaf type
springs, become wedged between the locking ramps and the shaft
to transmit torque between the two members. Either the member
housing the clutch drives the shaft in one direction, or the shaft can
drive the clutch and its housing member in the other direction.

Operation is in two modes; the overrun mode and the lock mode.
Operational mode is controlled by the direction of the clutch or
shaft rotation with respect to the locking ramps.
In the overrun mode shown in the drawings below, the relative
rotation between the housed clutch and the shaft causes the
rollers to move away from their locking position against the locking
ramps in the drawn cup. The housing and the clutch are then free
to overrun in one direction, or the shaft is free to overrun in the
other direction.

In many respects, construction is similar to that of drawn cup
bearings. Design and manufacture of drawn cup clutches, just
as with drawn cup bearings, was pioneered and developed by
Timken. The well established design utilizes the same low profile
radial section as drawn cup bearings. The precisely formed interior
ramps provide surfaces against which the needle rollers wedge to
positively lock the clutch with the shaft when rotated in the proper
direction. These ramps, formed during the operation of drawing the
cup, are case hardened to assure long wear life. The incorporation
of ramp forming into the cup drawing operation is a manufacturing
innovation that contributes much to the low cost of the unit.
Two designs of precision molded clutch cages are employed.
Clutch and clutch and bearing assembly types FC, FC-K, FCS, FCLK, RC-FS, FCB, FCBL-K and RCB-FS use a glass fiber reinforced
nylon cage equipped with inserted stainless steel leaf springs. The
stainless steel springs permit higher rates of clutch engagement
and achieve greater spring life. The nylon cage permits operation
at higher temperatures. Clutch types RC and RCB utilize a onepiece cage of acetyl resin plastic with integral leaf style springs
used for lower temperatures than permitted for the units with
nylon cages.
Types FCB, FCBL-K, RCB and RCB-FS clutch and bearing
assemblies have cages for retention and guidance of the needle
rollers in the bearings located on both sides of the clutch unit.

Application
Timken ® Torrington ® clutches and clutch and bearing
assemblies are successfully applied in a wide range of commercial
products where indexing, backstopping and overrunning operations
must be performed reliably. The sketches on these pages illustrate
some of the many possible uses.
When applying the clutch-only unit, separate bearings on each
side of the clutch are required to position the shaft concentrically
with the housing and to carry the radial loads during overrun. Drawn
cup needle roller bearings with the same radial section as the
clutch should be used in the through bored housings for simplicity
and economy. Two clutches can be used side by side for greater
torque capacity.
Where the radial loads are light, the clutch and bearing assembly
can be used without additional support bearings. This reduces the
overall assembly width, the number of stocked and ordered parts,
and assembly costs as well.
Timken Torrington drawn cup roller clutches are manufactured
to commercial hardware standards and are used extensively
in appliances, business machines, industrial and recreation
equipment and a wide range of other applications.

Consideration should be given to the shaft and housing design
requirements such as:
Shaft hardness and strength particularly when approaching
torque rating limits.
Shaft roundness, taper and surface finish necessary to
ensure sufficient fatigue life and torque carrying ability.
Housing strength [hardness and cross section] to support the
applied torque loads.
Housing roundness, taper and surface finish necessary to
ensure uniform torque and load distribution.
A test program under all expected operating conditions should
be carried out before putting a new application into production.
Timken customer engineers are constantly working with and testing
new applications, and, their experience can be of great help to the
designer considering the use of a drawn cup roller clutch.

made, it is important that the following catalog section be carefully
studied to understand the effects of these factors. Consideration
should be given to operating conditions such as:
Magnitude of externally applied torque as well as inertial
torque.
Magnitude of applied radial loads during overrunning.
Potential for vibration or axial shaft movement within the

realize this benefit. Steel housings are preferred and must be
used for applications involving high torque loads to prevent radial
expansion of the clutch cups. The suggested minimum housing
outside diameters in the tables of dimensions are for steel.
The housing bore should be round within one-half of the
diameter tolerance.
The taper within the length of the outer ring should not exceed
0.013 mm (.0005 inch).
The surface finish of the housing bore should not exceed
1.6 mm Ra (63 microinches Ra).
The torque ratings given in the clutch tables are based on a
steel housing of a large section. When other housing material
must be used (such as aluminum, powdered metal and plastics)
the torque rating of the clutch will be reduced. Such housings may
be satisfactory for lightly torqued applications but your Timken
representative should be consulted for appropriate housing and
shaft suggestions. Otherwise, an insufficient press fit and use
of a lower strength housing material can result in more internal
clearance and reduced performance of the clutch.
When using non-steel housings, thorough testing of the design
is suggested.
Adhesive compounds can be used to prevent creeping rotation
of the clutch in plastic housings with low friction properties.
Adhesives will not provide proper support in oversized metal
housings. When using adhesives, care must be taken to keep the
adhesive out of the clutches and bearings.

Housing Design
Drawn cup clutches and clutch and bearing assemblies are
mounted with a simple press fit in their housings. Through-bored
and chamfered housings are preferred. A 30˚ angle is suggested
and care should be taken to round the edge where the chamfer
meets the housing bore. A sharp edge at this location can greatly
increase installation forces. Provisions for axial location, such
as shoulders or snap rings, are not required. The case hardened
cups have a long fatigue life, but must be properly supported to
The clutch or clutch and bearing assembly operates directly on
the shaft whose specifications of dimension, hardness and surface
finish are well within standard manufacturing limits.
Either case hardening or through-hardening grades of good
bearing quality steel are satisfactory for raceways. Steels
modified for free machining, such as those high in sulfur content
and particularly those containing lead, are seldom satisfactory
for raceways.
For long fatigue life, the shaft raceway, must have a hardness
equivalent to 58 HRC, and ground to the suggested diameter shown
in the tables of dimensions. It may be through hardened, or it may
be case hardened, with an effective case depth of 0.4 mm (0.015
inch). (Effective case depth is defined as the distance from the
surface inward to the equivalent of 50 HRC hardness level after
grinding.)
Taper within the length of the raceway should not exceed 0.008
mm (0.0003 inch), or one-half the diameter tolerance, whichever is
smaller. The radial deviation from true circular form of the raceway
should not exceed 0.0025 mm (0.0001 inch) for diameters up to
and including 25 mm (1.0 inch). For raceways greater than 25 mm
(1.0 inch) the allowable radial deviation should not exceed 0.0025
mm (0.0001 inch) multiplied by a factor of the raceway diameter
divided by 25 (1.0 inch). Surface finish on the raceway should not
exceed 0.4 mm (16 microinches) Ra. Deviations will reduce the load
capacity and fatigue life of the shaft.

Installation
Simplicity of installation promotes additional cost savings. The
drawn cup roller clutch, or the clutch and bearing assembly, must
be pressed into its housing. Procedures are virtually identical with
those for installing drawn cup bearings as detailed on pages C40
and C62. The unit is pressed into the bore of a gear hub or pulley
hub, or housing of the proper size, and no shoulders, splines, keys,
screws or snap rings are required.
Installation procedures are summarized in the following
sketches:
C
IMPORTANT: The mounted clutch or clutch and bearing
assembly engages when the housing is rotated relative to the shaft
in the direction of the arrow and LOCK marking [LOCK] stamped
on the cup. Make sure that the unit is oriented properly before
pressing it into its housing.

Pilot during installation
If clutch is straddled by needle roller bearings, press units
into position in proper sequence and preferably leave a small
clearance between units.
When assembling the shaft, it should be rotated in the overrun
direction during insertion. The end of the shaft should have a large
chamfer or rounding.
Drawn Cup Roller Clutches
Applied Loads
The clutch-only unit is designed to transmit purely torque
loads. Applied torque should not exceed the catalog ratings which
are based on the compressive strength of well-aligned clutch
components. Bearings on either side of the clutch are to assure
concentricity between the shaft and the housing and to support
radial loads during clutch overrun. Integral clutch and bearing
assemblies are available for this purpose where the radial loads
are light. The total maximum dynamic radial load that may be shared
by the two needle roller and cage radial bearing assemblies should
not be greater than C/ 3.
In determining the total torque load on a clutch, it is essential
to consider the torque due to inertial forces developed in the
mechanism, in addition to the externally applied torque. The larger
the clutch and the greater the mass of the mechanism controlled
by it, the more important this consideration becomes.
Clutch lockup depends on friction. For this reason applications
involving severe vibrations or axial motion of the shaft within
the clutch are to be avoided. The applications where there are
overhanging or overturning loads should incorporate bearings that
will maintain alignment between the shaft and the clutch housing.
Consult your Timken representative for suggestions.
Lubrication
Oil is the preferred lubricant, as it minimizes wear and heat generation. For those applications where oil is not practical, clutches
are packed with a soft grease containing mineral oil. Thick grease
will retard roller engagement and can cause individual rollers to
slip, possibly overloading any engaged rollers.
Temperature
Temperature extremes can cause clutch malfunctions and
failure. The molded plastic cage with integral springs holds its
necessary resiliency and strength when the operating temperature
within the clutch is kept below 90 degrees Celsius (200 degrees
Fahrenheit). The clutch with reinforced nylon cage and separate
steel springs operates well at temperatures up to 120 degrees C
(250 degrees Fahrenheit) continuously and to 150 degrees Celsius
(300 degrees Fahrenheit) intermittently. Excessive thickening of
the lubricant at low temperatures may prevent some or all of the
rollers from engaging. New applications should be tested under
expected operating conditions to determine whether or not temperature problems exist.
A
Rate Of Engagement
Clutch lockup depends upon static friction. Axial motion
between shaft and clutch rollers prevents lockup.
Clutches with integral springs engage satisfactorily at cyclic
rates up to 200 engagements per minute. Intermittent operation at
higher rates has been successful. The steel spring type clutches
have proven dependability at rates up to 6000 or 7000 engagements
per minute. Even higher cyclic rates may be practical. Since grease
may impair engagement at high cyclic rates, a light oil should be
used.
Overrun Limit Speed
Exact limiting speeds are not easily predictable. The value for
each clutch given in the tabular data is not absolute but serves as
a guide for the designer. Oil lubrication is absolutely necessary for
high speed operations. Consult your Timken representative when
overrunning speeds are high.
A
CA
Inspection
Although the outer cup of the clutch is accurately drawn from
strip steel, it can go slightly out of round during heat treat. When the
assembly is pressed into a ring gage or properly prepared housing
of correct size and wall thickness, it becomes round and properly
sized. Direct measurement of the outside diameter of a drawn
cup assembly is an incorrect procedure. The proper inspection
procedure is as follows:
1. Press the assembly into a ring gage of the proper size as
given in the tabular data.
2. Gage the bore with the specified plug gages of the proper
size, as given in the tables of dimensions.
a. The locking plug is rotated to insure lockup when the clutch is operated at low limit shaft and is mounted in
a high limit housing strong enough to properly size
the clutch.
b. The overrun plug is rotated to ensure free over-running when the clutch is operated on a high limit shaft and
is mounted in a low limit housing.
c. The go plug and no go plug insure proper size of the bearings in the clutch and bearing assemblies.
Gage sizes are listed in the tables of dimensions. Plug gage
sizes reflect adjustment for the loose and tight conditions resulting
from high or low housings or shafts.
Backlash
A
A
A
A
Backlash, or lost motion, prior to engagement is minimal. The
variation in backlash from one cycle to another is extremely low.
Grease lubrication or improper fitup [housing bore and shaft
diameter] may increase backlash. Angular displacement between
the shaft and housing increases as an applied torque load is
increased.

NEEDLE ROLLER BEARING ACCESSORIES
NEEDLE/CYLINDRICAL ROLLERS
Overview: Loose needle and cylindrical rollers are mainly used as bearing rolling elements to
reduce friction and torque in rotating and pivoting applications. However, these precision rollers
have many other uses such as shafts or locating pins.
A
•S
izes: Diameters from 1.5 mm (0.0591 in.) to 14 mm (0.551 in.). Lengths from 5 mm (0.20 in.)
to 57.2 mm (1.25 in.).
•M
arkets: Vehicle and industrial transmissions, universal joints, and two-cycle engines.
• F eatures: Cylindrical and needle sizes are available. Needle rollers are available with
flat and rounded ends, metric series needle rollers available in Grade 2, 3 or 5.
CA
•B
enefits: Provide the maximum load carrying capacity within the smallest envelope
at a low cost.
METRIC INNER RINGS
Overview: Inner rings are made from bearing quality steel and their O.D. and bore are precision
ground. They function as the inner raceway for a needle roller bearing by providing a surface
that meets all shaft raceway design requirements (hardness, surface finish, roundness, etc.).
•S
izes: 5 mm (0.197 in.) bore to 180 mm (7.087 in.) outside diameter.
•M
arkets: Automotive, truck, power transmissions, and industrial
applications.
A
• F eatures: Available with and without chamfers, some are
available with a profiled outside diameter.
•B
enefits: When it is not practical to manufacture the shaft to
raceway quality, an inner ring allows a customer to obtain
acceptable bearing performance.

Needle Rollers – Metric Series
Needle rollers are made from rolling bearing quality steel
hardened to 60-64 HRC or equivalent. Nominal metric needle rollers
in various grades are standardized at national and international
levels. The grades determine the dimensional and form tolerances
of the needle rollers. Metric series needle rollers may differ by
their end form: type A has rounded ends and type B has flat ends.
Timken prefers to supply needle rollers in the most economical
flat end or type B design in G2 grade. Metric series needle rollers
of type A may also be made available on request, and in other G3
or G5 grades.
Metric Series Needle Roller Dimensions
A
A
Nominally metric needle rollers, conforming to the International
Standard ISO 3096, are shown in Table 1. The symbols used in
Table 1 as well as in subsequent tables and figures are summarized
in Table 5. Needle rollers with flat ends, which are the preferred
design are shown in Table 1. Chamfer dimension limits are also
shown, the use of which results in the maximum possible effective
contact length between roller and raceway. Yet, the relieves at the
needle roller ends help to reduce stress concentration resulting
in more uniform stress distribution, optimum load ratings, and
longer life.
Every needle roller gage is separately packed and the
packages are marked accordingly.

Designation and Package Marking:
NRO.B1,5x13,8G2
M2M4
NRO – Needle roller
.B – Flat end needle rollers
1,5 – Nominal diameter Dw = 1,5 mm
13,8 – Nominal length Lw = 13,8 mm
G2 – Needle roller grade (see table 2)
rev2.9Dec98
Page 4-15
M2M4 – deviation of needle roller gage -2/-4 mm
The actual finished diameter is between 1.498 and 1.496 mm.
In the marking of the needle roller gage, P identifies zero (0)
or plus (+), M identifies minus (-). If a shipment of needle rollers
of the same size comprises several boxes, each box contains
needle rollers of the same grade. The gage may vary from box
to box. Each individual box, however, contains needle rollers of
identical gage.

Design Calculations For Needle
Roller Bearing Complements
In the majority of full complement needle roller applications,
needle roller complements of less than 35 needle rollers per row and
a ratio of length to diameter between 4:1 and 8:1 is advantageous.
Other combinations of quantity and length to diameter ratios
of needle rollers have been used successfully. Specific design
requirements usually dictate the appropriate selection.
In general, needle roller complements for rotating motion
should employ a smaller number of large diameter needle rollers,
while needle roller complements subjected to oscillating motion
(especially under high loads) should employ a large number of
smaller diameter needle rollers.
Oscillating applications with small angular travel encourage
the development of fretting corrosion. The best performance under
these conditions has been achieved by using the largest practical
number of small diameter needle rollers.
Calculation Of Raceway Diameters

Note 1 - Tolerance values apply only at the middle of the needle roller length.
Note 2 - Needle rollers of any nominal dimensions and any of the quoted grades will be supplied sub-divided into the gages listed in Table 2 at our option,
if nothing to the contrary is agreed upon at the time of ordering.
Table 3 specifies the applicable end configuration for rounded
end and flat end needle rollers of all grades.

The calculation of inner and outer raceway diameters may
be carried out using either the formula given in Table 5 or more
conveniently the raceway calculation form in Table 6. To assist the
designer in making these calculations, the values of K required for
calculation of needle roller complements of 6 through 60 needle
rollers are listed in Table 7. Values of K for other numbers of needle
rollers can be calculated using the formulas given in Table 5.
Table 8 lists the suggested values for minimum radial internal
clearance (Gr min) and the minimum circumferential clearance
divided by π (cc min/π), to be used for calculating needle roller
complements for normal rotating applications where the speeds,
loads and shaft deflections are moderate.
Applications with poor lubrication, unusual motion, large
misalignment, raceway distortions, load reversals, high speeds, etc.
can not be characterized as normal rotating applications. These
miscellaneous applications require adjustment of the minimum
clearances listed in Table 8. The factors in Table 9 may be used
for general guidance in the adjustment of the minimal clearances.
For any of the listed miscellaneous applications or any application
where abnormal factors such as those listed above exist, and
particularly when the inner raceway diameter will exceed 50 mm,
consult your Timken representative for design assistance.

CLEARANCES IN NEEDLE ROLLER COMPLEMENTS
Needle rollers, supplied in bulk, are generally used for full
complement assemblies. Successful operation of a full complement
of needlerollers not only requires careful selection of radial internal
clearance but, more importantly, depends on proper circumferential
clearance, or the total clearance between needle rollers.
Needle roller guidance in a full complement assembly depends
largely on contact between needle rollers. Too little circumferential
clearance causes overheating. Too much circumferential clearance
ina heavily loaded full complement of needle rollers causes loss
of needle roller guidance and results in needle roller skew and
resultant end thrusting.
Control of radial clearance and circumferential clearance is
influenced by the needle roller diameter tolerance, as well as the
tolerances of the inner and outer raceway diameters.

Load Rating and Life Calculations for Full Complements
of Needle Rollers
Before selecting the quantity and size of needle rollers to be
used in a needle roller complement, it is usually necessary to
calculate the load rating required using the applied load, speed
and desired life. For a review of bearing size selection, see the
engineering section.
Since it is not practical to tabulate the dynamic and static load
ratings for the great number of needle roller complements that can
be assembled by using different quantities, diameters and lengths
of rollers, formulae are provided for the necessary calculations.
For convenience, values of fc and values of Z 3/4 have been
combined into single factors (fc • Z 3/4). These factors for a wide
range of roller complements are tabulated in Table 11.
Basic Dynamic Load Ratings
The basic dynamic load rating C, for any roller bearing can be
calculated from the formula:
C = fc • (i • Lwe • cos α) 7/9 • Z 3/4 • Dwe 29/27
where: fc = a factor which depends on the geometry of
the bearing components, the accuracy to which the various
components are made, and the material. Maximum values
are listed in such standards as ISO 281 and USA ANSI-ABMA
Standard 11.
i = number of rows of rollers in any one bearing.
α = nominal angle of contact. Since a = 0 for a radial
roller bearing, cos α = 1.
Other symbols are explained in Table 5.
For single path radial roller bearings, where i = 1 and
cos α = 1, the basic dynamic load rating formula can be written as:
C = fc • Z 3/4 • Lwe 7/9 • Dwe 29/27

Example:
Calculate the basic dynamic load rating for a full complement
of 28 flat end rollers, 3 mm diameter and 17.8 mm length.
A
C = fc • Z 3/4 • Lwe 7/9 • Dwe 29/27
fc Z 3/4 from Table 11 = 1145
Dwe29/27 = 3 29/27 = 3,254
Lwe= 17.8- 0.2 = 17.6 mm
Lwe 7/9 = 17.6 7/9 = 9305
A
CA
C = 1145 • 9305 • 3254 = 34.7 kN
When a couple load (overturning moment) is imposed on a single
row of needle rollers, the resulting uneven distribution of load can
seriously affect bearing life. In such cases, two rows of needle
rollers are generally suggested.
Basic Static Load Rating
The basic static load rating (C0) for any roller bearing, including
needle roller bearings, can be calculated from the following
formula included in ISO 76, USA ANSI-ABMA Standard 11, and
other Standards:
C0= f0 • (1 -
Dwe • cos α
Dpw
A
) • i • Z • Lwe • Dwe cos α
where: f0= 0,044 when kilo-newton and
millimeter units are used.
Dpw = pitch diameter of the needle roller
complement (mm).
A
i
= number of rows of rollers in any one
bearing.
α = nominal angle of contact. Since α = 0
for radial roller bearing, cos α = 1.

The other symbols are described in Table 5.

Before selecting a specific needle roller complement, the
engineering section of this catalog should be reviewed for detailed
information concerning:
bearing type selection
bearing life and reliability
definition of load ratings
life and load relationships
effect of raceway hardness
example of life calculation
lubrication
shaft design
housing design
In addition to these general considerations, material which
follows should also be reviewed when selecting a needle roller
complement.
Standard inch series needle rollers are furnished in two
styles – elliptical end or the most economical design: flat end.
Materials, dimensions and tolerances for standard needle rollers
are specified in this section.
When required, needle rollers having spherical ends, conical
ends, trunnion ends or crank pin ends, as well as other end designs,
can be furnished. Your Timken representative should be consulted
before final needle roller selection is made.

Inch Series – Needle Roller Dimensions
Needle rollers are made from rolling bearing quality steel
hardened to 60-64 HRC or equivalent. Nominally inch needle
rollers are given in Table 1. Your Timken representative should be
consulted for availability. The symbols used in Tables 1 as well as
in subsequent tables and figures are summarized in Table 2.
Needle rollers with elliptical ends permit the use of a more generous
fillet between the raceway and the locating shoulder than possible
with flat end rollers. Also, due to the length of the elliptical end, the
possibility of the roller’s cylindrical surface operating over the edge
of the raceway is less, thus reducing the chance of occurrence of
harmful stress concentrations. On the other hand, where design
considerations permit their use, flat end rollers achieve the
maximum possible effective contact length between roller and
raceway along with maximum load ratings and longer life.

Circumferential guidance in a full complement of needle rollers
depends largely on roller-to-roller contact. Too little circumferential
clearance causes overheating. Too much circumferential clearance
in a heavily loaded full complement of needle rollers causes loss of
roller guidance and results in roller skew and heavy end thrust.
Control of radial clearance and circumferential clearance
is influenced by the roller diameter tolerance, as well as the
tolerances of the inner and outer raceway diameters.
CA
End Clearance
The total needle roller end clearance, or end play, normally
should be 0.008 inch minimum per path of needle rollers.
Nominal Inch Needle Rollers Tolerances
Unless otherwise specified, inch needle rollers are normally
manufactured with a tolerance of +0.0000 in. -0.0002 in. This
tolerance has proven acceptable and ensures satisfactory control
of circumferential clearance. The needle roller length tolerance may
vary with the end configuration. The normal roller length tolerance
rev2.9Dec98
Page 4-15
for rounded end rollers is +0.000 in. -0.020 in.
Timken also manufactures needle rollers with 0.0001 in.
diameter tolerance. These offer enhanced load carrying capability
and improved control of circumferential clearance. For needle
rollers of greater precision, please consult with your Timken
representative.
Nominal dimensions for typical inch series needle rollers are
shown in Table 1. Timken supplies rollers with smaller and larger
length-to-diameter ratios for special applications. Rollers with
dimensions other than those shown in Table 1 can be obtained
provided the quantities permit economical production. For example,
although the largest needle rollers shown in Table 1 are 0.2500 in.
(the usual limits for needle rollers), Timken produces quantities of
rollers as large as 0.6250 in. diameter.
Your Timken representative should be contacted with the
following information about the required needle rollers:
• nominal metric or inch
• diameter and tolerance (e.g., .1250 in., + 0 in. -.0002 in.)
• length and tolerance (e.g., .560 in., + 0 in. -.020 in.)
• end form (e.g., elliptical end or flat end)
• material (e.g., high carbon chrome steel)
• special features required (e.g., Controlled Stress)
• quantity required

Needle rollers, supplied in bulk, are generally used to assemble
full complement bearings. Successful operation of a full complement
of rollers not only requires careful selection of radial clearance but,
more importantly, depends on proper circumferential clearance,
or the total clearance between rollers.

In the majority of full complement needle roller applications, roller
complements of less than 35 needle rollers per row and a ratio of roller
length to roller diameter between 4:1 and 8:1 is advantageous. Other
combinations of quantity and length-to-diameter ratios of needle rollers
have been used successfully. Specific design requirements usually
dictate the appropriate selection.
In general, roller complements for rotating motion should employ
a smaller number of larger diameter needle rollers, while roller
complements subjected to oscillating motion (especially under
high loads) should employ a larger number of smaller diameter
needle rollers.
Oscillating applications with small angular travel encourage
the development of fretting corrosion. The best performance under
these conditions has been achieved by using the largest practical
number of small diameter needle rollers.
Calculation of Raceway Diameters
It may be convenient to use the Bearing Calculation Form in
Table 3 to calculate the maximum inner raceway and the minimum
outer raceway diameters of a bearing. The formula given in
Table 2 can also be used. To assist the designer in making these
calculations, the values of K required for calculation of needle roller
complements of 6 through 60 needle rollers are listed in Table 4.
Values of K for other numbers of needle rollers will be furnished on
request, or can be calculated from the formula given in Table 2.
Table 5 lists the suggested values for minimum radial clearance
and (Gr min) minimum circumferential clearance divided by π (ccmin/
π), to be used for calculating needle roller complements for normal
rotating applications where the speeds, loads and shaft deflections
are moderate.
Applications with poor lubrication, unusual motion, large
misalignment, raceway distortions, load reversals, high speeds,
etc., can not be characterized as normal rotating applications.
These miscellaneous applications require adjustment of the
minimum clearances listed in Table 5. The factors in Table 6 may
be used for general guidance in the adjustment of the minimal
clearances. For any of the listed miscellaneous applications or
any application where abnormal factors such as those listed
above exist, and particularly when the inner raceway diameter will
exceed 2 inches, your Timken representative should be consulted
for design assistance.

Load Rating And Life Calculations
For Full Complements Of Needle Rollers
Table 7 – Suggested Raceway
Diameter Tolerances
Before selecting the quantity and size of needle rollers to be
used in a needle roller complement, it is usually necessary to
calculate the load rating required using the applied load, speed
and desired life. For a review of bearing size selection, see the
engineering section.
Since it is not practical to tabulate the dynamic and static load
ratings for the great number of needle roller complements that can
be assembled by using different quantities, diameters and lengths
of rollers, formulae are provided for the necessary calculations.
For convenience, values of fc and values of Z 3⁄4 have been
combined into single factors (fc • Z 3⁄4). These factors for a wide
range of needle roller complements are contained in Table 9.

components, the accuracy to which the various components are made, and the material. Maximum values
are listed in such standards as ISO 281 and USA ANSIABMA Standard 11.
Keystoned Roller Assemblies
Retention of the rollers in the outer raceway by key-stoning can
be helpful in assembly operations. The following formula may be
used to check the bearing design to be sure that a given number
of rollers, Z, will keystone.
A
That is, the product of the keystone constant Y, given below,
and the minimum roller diameter Dw min, must be greater than the
maximum outer race bore, Emax.
Roller complements with 14 or more rollers usually will not
keystone unless steps are taken to reduce the circumferential
clearance. It is suggested that your Timken representative be
consulted when designing a keystoned roller complement with
14 or more rollers.

Calculate the basic dynamic load rating in lbf for a
full complement of 28 elliptical end rollers, 0.1250 in. diameter and
0.750 in. length.
C = fc • Z 3/4 • Lwe 7/9 • Dwe 29/27
fc Z 3/4 from Table 9 = 102900
Dwe 29/27 = 0.1250 29/27 = 0.1072
Lwe= 0.750 - (0.4 • 0.1250) = 0.700 (see Table 2)
Lwe 7/9 = 0.700 7/9 = 0.758

C = 102900 • 0.1072 • 0.758 = 8360 lbf
When a couple load (overturning moment) is imposed on a
single row of needle rollers, the resulting uneven distribution of
load can seriously affect bearing life. In such cases, two rows of
needle rollers are generally suggested.
Your Timken representative should be consulted before a final
selection of a needle roller complement is made.
Basic Static Load Rating
The basic static load rating (C0) for any roller bearing, including
needle roller bearings, can be calculated from the following
formula included in ISO 76, USA ANSI-ABMA Standard 11 and other
Standards:
C0= f0 • (1 -
Dwe • cos
Dpw
A
) i Z Lwe Dwe cos α
where: f0= 6430 when pound-force and inch units
are used
A
Dpw = pitch diameter of the needle roller
complement (inch).
i
= number of rows of rollers in any one
bearing.
A
α = nominal angle of contact. Since α = 0
for radial roller bearing, cos α = 1.
The other symbols are described in Table 2.

Timken® Torrington® cylindrical rollers are made from bearing
quality steel and hardened to 58-65 HRC or equivalent. Nominal
metric cylindrical rollers are sorted into gages based on the mean
deviation from nominal diameter and nominal length. The relieved
ends of the cylindrical rollers, when used in bearing complements,
help to reduce stress concentration at the ends of rollers, both
under misalignment or ideal alignment. This results in a more
uniform stress distribution along the roller-raceway contact length
and optimum bearing performance.

Nominally metric cylindrical rollers conforming to DIN 5402
sheet 1 are shown in Table 1. Chamfer dimension limits of these

are also shown in Table 1. The use
of these chamfer limits results in the maximum possible effective
contact length between roller and raceway, along with the already
mentioned relieved ends, producing the maximum possible load
ratings and longer life.
Each cylindrical roller gage is packed separately and the mean
deviations of diameter and length gages are shown on the package
(below the roller designation).

Inner Rings – Metric Series
Construction
Metric series inner rings are available in four basic designs and
differ only by the chamfers at the ends of the raceway surfaces,
the lubricant access holes and the raceway profile. Inner rings
of series JR have chamfers to assist in bearing installation but
are without lubricating holes. Inner rings of series JR and IM
have bearing installation chamfers and lubricating holes (bore
diameters 5 to 50 mm). Inner rings of series JRZ.JS1 are without
installation chamfers, allowing for maximum possible raceway
contact. IM...RG6 inner rings have a profiled outer diameter for use
in applications having a greater degree of misalignment.
The BIC and BICG Series inner rings have chamfers and oil
holes and are designed to be used with the full complement, metric,
needle roller bearings of Series RNA1000, RNA2000 and RNA3000.
These inner rings are intended for RNA bearings of the same
number; for example a BIC2020 would be used with a RNA2020.
Dimensional Accuracy
The tolerances of size, form, and runout for metric series
inner rings meet the requirements of ISO normal tolerance class
for radial bearings (see the engineering section). Most metric
series inner rings are produced with outside diameter raceway
tolerance in accordance with h5 which, in most cases, is suitable
for combining the metric series needle roller bearings to give the
normal clearance class, and for use with drawn cup bearings. Other
raceway tolerances may also be found on inner rings for combining
with needle roller bearings to give one of the clearance classes, or
other specially requested radial internal clearance requirement.
Mounting of Inner Rings
Inner rings may be mounted on the shaft with either a loose
transition fit or an interference fit. These fits used in conjunction
with the proper fit of the bearing outer ring, will provide the correct
operating clearances for most applications.
Regardless of the fit of the inner ring on the shaft, the inner
ring should be axially located by shaft shoulders or other positive
means. The shaft shoulder diameter adjacent to the inner ring must
not exceed the inner ring outside diameter (per suggestions on
page C103 of the metric series needle roller bearing section).
When metric series inner rings are to be used with the metric
series needle roller bearings, appropriate shaft tolerances should
be selected from Table 3 in the metric series needle roller bearing
section. When metric series inner rings are to be used with drawn
cup bearings the suggested shaft tolerances are given in the
“Inner ring” discussion on page C39 of the “metric series drawn
cup needle roller bearings” section of this catalog.
A
A
A
Inch Series Inner Rings
Inch series inner rings for use with inch series drawn cup
bearings are tabulated on page C92 of this catalog. See catalog
page C150 for inch series inner rings for use with inch series needle
roller bearings.
A
End Washers – Metric Series
When the metric series needle roller and cage radial assembly
used in series NAO and RNAO needle roller bearings without
flanges cannot be axially located by suitable shoulders or side
faces, end washers of series SNSH may be used. These end
washers, which are made of spring steel, are designed to be guided
in the housing bore. They are tabulated on page C353.
TIMKEN PRODUCTS CATALOG
C337
•
When it is impractical to meet the shaft raceway design
requirements (hardness, surface finish, case depth, etc.) outlined
in the engineering section of this catalog, standard inner rings
may be used.
Inner rings are made of rolling bearing steel and after hardening,
their bores, raceways and end surfaces are ground. Metric series
inner rings may be used to provide inner raceway surfaces for
metric series needle roller and cage radial assemblies, metric
series needle roller bearings and metric series drawn cup needle
roller bearings. The extended inner rings are suitable for use with
bearings containing lip contact seals and for applications in which
axial movement may be present.
