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.

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. over mm - 19 28 32 35 40 52 72 90 110 incl. deDe Bw e 19 28 32 35 40 52 72 90 110 - 6 10 12 16 18 20 24 30 36 42 7.5 10.5 11.5 15.1 17.1 19.1 24.1 30.7 36.5 43.5 0.5 1.0 1.0 1.5 1.5 2.0 3.0 3.0 3.0 3.0 9 14 16 21 24 27 36 42 48 54 TIMKEN PRODUCTS CATALOG C163 A • > mm 19 30 40 62 80 Be 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. Inner raceway quality requirements are given in the engineering section of this catalog. 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. • A 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. C164 TIMKEN PRODUCTS CATALOG 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.

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.

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. d4 Dk A H1 Table 7 – Metric Series Grease Fittings, Series VENN Table 8 – Installation Tool For Metric Series Plug DesignationDimensions mmWt. g approx.

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. • A Construction feature code letters for inch series track rollers are used as required, in the following order: S - seals with internal thrust washers B - hexagonal wrench socket in stud head (stud type only) C - profiled outer ring E - eccentric stud (stud type only) C206 TIMKEN PRODUCTS CATALOG YCR for Yoke Mounting Table 1 – Identification Code – Inch Series Prefix LettersSuffix Numbers Complete type plus construction features plus O.D. equals size CR plus plus CR plus SBE Designation -16 equals CRSBE-16 -16 equals CR-16 Table 2 – Code Description – Inch Series Stud Types Description Prefix Code with seals and internal thrust washers CRS with seals, internal thrust washers and profiled outer ring CRSC with seals, internal thrust washers, hex socket and profiled outer ring CRSBC with seals, internal thrust washers, hex socket, profiled outer ring and eccentric stud CRSBCE Yoke Types with seals and internal thrust washers YCRS with seals, internal thrust washers and profiled outer ring YCRSC Stud Type and Yoke Type Track Rollers Construction 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.

A TIMKEN PRODUCTS CATALOG C207 • 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.

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 Table 4 – Hexagonal Wrench Sizes – Inch Series Dynamic Loading As A Track Roller SizeWrenchSizeWrench DesignationSizeDesignationSize (suffix) Inch (suffix) Inch -8 -8-1 -10 -10-1 1⁄ 8 1⁄ 8 1⁄ 8 1⁄ 8 -28 -30 -32 -36 5⁄ 16 5⁄ 16 7⁄ 16 7⁄ 16 -12 -14 -16 -18 -20 -22 -24 -26 3⁄ 16 3⁄ 16 1⁄ 4 1⁄4 -40 -44 -48 -52 -56 -64 1⁄ 2 1⁄ 2 3⁄4 3⁄4 • A Table 5 – Eccentric Bushing Dimensions Regular Stud Type (Type CR) C208 1⁄4 1⁄ 4 5⁄ 16 5⁄ 16 TIMKEN PRODUCTS CATALOG 3⁄4 3⁄4 than the maximum width of the eccentric bushing. 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 = Static radial load fs = Static factor whose valves should not be smaller than those suggested in table 6 Table 6 – suggested Values For Static Factors fs For Inch Series Track Rollers Requirements For Yoke Type Track Rollers And Stud Type Track RollersSuggested fs Values High shock-type loads Quiet running 1.5...2.5 Normal loading 1...1.5 Normal quietness of running Minor impact loads and rotary motion particularly 0.7...1 quiet running not required 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. CA A TIMKEN PRODUCTS CATALOG C209 • Static Loading NEEDLE Roller Bearings 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. • A C210 TIMKEN PRODUCTS CATALOG 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.

NEEDLE Roller Bearings NOTES C • A C222 TIMKEN PRODUCTS CATALOG 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.

They all have very small cross-sections. This catalog includes the most popular, standardized and non-standard designs. If back up surface cannot be used as a raceway, hardened washers are available. C Reference Standards Are: • ISO 3031 – Rolling bearings – Needle roller and cage thrust assemblies, thrust washers – Dimensions and tolerances • DIN 5405 Part 2 – Rolling bearings – Needle bearings – Thrust needle roller and cage assemblies. • DIN 5405 Part 3 – Rolling bearings – Needle bearings – Thrust washers • ANSI/ABMA Std. 21.1-1988 – Thrust needle roller and cage assemblies and thrust washers – Metric design. Before selecting specific needle roller and cage thrust assemblies, the engineering section of this catalog should be reviewed.

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. FNTF FNTK d Dc1 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. Page 153 • d A LS LS Heavy Thrust Thrust Washer Washer Heavy FNTKF AXK AXK FNTKF rev3.18Jan99 AXK AXK C228 TIMKEN PRODUCTS CATALOG Page 153 rev0.7Nov98 AS AS Thrust Wa Wa Thrust Needle Roller Thrust Bearings, Assemblies, Washers 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. A TIMKEN PRODUCTS CATALOG C229 • 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.

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.

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).

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.

NEEDLE Roller Bearings a Cylindrical Roller Thrust Bearings And Their Components Metric Series E C ra 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.

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.

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: H10 shaft Thick, thin and heavy series h10 H10 thrust washers Types: CP and CPR where CA Fa min = 0.1 • C0/2200 (kN) C0 – static load rating (kN) Fa min – minimum axial load (kN) as required 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.

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.

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.

CA A NEEDLE Roller Bearings Bore Inspection Procedure For Thrust Washer The bore diameter (d) of the thrust washer 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. Tolerances For Cylindrical Roller Thrust Bearings C 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.

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.

C296 C CA NEEDLE Roller Bearings COMBINED BEARINGS – Metric Series 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.

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.

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.

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. C LU H Operation CLU TC 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. NEEDLE Roller Bearings A A B C 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. Clutch & Bearing Arrangement Clutch & Bearing Assembly for Heavy Loads for Light Loads 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. • • • • Stair Steppers, and other Athletic Equipment A Lawnmower Differential Clutch and Bearing Arrangement In any Heavy application Loads where our clutch may be considered, it will be A A A part of a system in which the operating conditions and the clutch mounting will affect its function. Before any clutch selection is 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 clutch during engagement. Engagement rate, as it pertains to the selection of stainless steel or plastic leaf springs. Oil lubricant supply during high overrunning speeds. External and internal environmental temperatures that can affect clutch performance. Lubricant selection effect on clutch engagement.

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. A A CA motor backstop.eps Shaft Design Timing Motor Freewheels Washing Machine Transmission 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.

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.

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 Bearings A NOTES A B C A A A A • A C316 TIMKEN PRODUCTS CATALOG Needle Rollers A 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.

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. A A • A C322 TIMKEN PRODUCTS CATALOG Reference standards are: • ISO 3096 – Rolling bearings – Needle rollers – Dimensions and tolerances • DIN 5402 – Sheet 3 – Rolling bearing components – Needle rollers.

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.

Table 4 – Tolerances for Needle Roller Length, Nominal Metric Needle Rollers Nominal Length, Lw mm Tolerance Limits mm (ISO h13) A 1.5 2.5 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.

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.

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.

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.

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.

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.

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. Clearances In Needle Roller Complements A LW Rounded Rounded End End Introduction DW r DW RW 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 A A A A 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.

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. • A 1 1.12 1.25 1.38 1.5 1.75 2 2.25 2.5 • • Indicates preferred needle roller sizes.

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.

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. Metric Series Cylindrical Roller Dimensions A A Nominally metric cylindrical rollers conforming to DIN 5402 sheet 1 are shown in Table 1. Chamfer dimension limits of these rev1.1Dec98 cylindrical rollers with flatPage ends4-8 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 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.
