RINGFEDER® Shrink Discs®
Characteristics
The Shrink Disc® is the modern method for creating a mechanical shrink fit. The Shrink Disc® consists of either one or two
thrust rings with tapered bores and a mating tapered inner ring.
By tightening locking screws the thrust rings are drawn together
compressing the inner ring and applying pressure to the outside of
the hub clamping it to the shaft. Being positioned around the hub
there is only one interface transmitting the loads giving the Shrink
Disc® method distinct advantages such as offering the possibility
of very concentric and well balanced connections that are suited to
high speed applications. Traditional shrink fits require complicated
calculations, close machining tolerances and fine surface finishes.
They also need considerable effort with mounting and removal.
The Shrink Disc® connection has none of these disadvantages
and is better than any of the other usual connection methods with
regard to fatigue strength under alternating torsional stress.

Unlimited range of applications – RINGFEDER® Shrink Disc® connections are suitable for securing all types of hubs onto shafts and
axles. Replacing traditional shrink fits, keys and polygon connections, splined shafts etc.
Explanations to tables
d, D, L, l, L1, L2, d1 = Basic dimensions
Additional loads, e.g. tension, thrust or bending have to be
taken into consideration accordingly.
dW =solid shaft diameter (provided by the customer)
T
=transmissible torque
Fax =transmissible axial force
p =approx. surface pressure on the hub extension
(diameter d)
TA =required tightening torque per screw
(Screws greased with molykote or equivalent!)
n
=quantity of screws
Function values
The functional characteristics are valid with the screw tightening torque listed in the tables and the following assumed
conditions:
The locking screws are lubricated using MoS2 (µtot= 0.1).
The tapered cones are lubricated using MoS2 (µ = 0.05).
The contact surfaces (dw ) are in lightly oiled condition with
coefficient of friction µ = 0.12.
The hub and shaft materials have a modulus of elasticity of
30 x 106 PSI. (Lower values­result in increased values for T
and Fax with reduced tangential stress.)
Tmax =maximum theoretical transmissible torque
Cw = shaft clearances
Ch = hub tolerances
Cd = shaft tolerances
|1
= Inner ring centering shoulder length
d2
= clamped component bore
x
= clamped component thickness
B
= width dimension, relaxed condition
The maximum clearance is being fully utilized.
The shaft being used is solid, for hollow shaft applications
the functional values will change.
In cases where the assumed conditions do not apply then
contact our Technical Department where we will be happy to
assist you with your application.
R1 = hub max. radius (split Shrink Disc®)
sv
=calculated combined stress in the hub extension
(d/dw) under consideration of the tangential, radial
and torsional stresses following the equation:

RINGFEDER® Shrink Discs®
Light Duty Series
Characteristics
Reduced dimensions with lower transmission values – especially
for applications with restricted space.
Simplified manufacture – only plain shaft and bore diameters with
easily achieved surface finish and tolerances are required.
Easy adjustability – No stops, steps, keyways, splines etc. are required, therefore hubs can be located and locked at any point or angle
on the shaft.
Easy mounting – RINGFEDER® Shrink Discs® use standard screws
and tightened using standard tools. No additional machining or fitting
work is required.
Easy removal – after loosening the locking screws, the
RINGFEDER® Shrink Disc® will self release and the hub will move
freely on the shaft.
Low susceptibility to contamination – when the locking screws are
tightened the contact (functional) surfaces are pressed firmly together
and prevent contamination by dirt and moisture.
Highest reliability – due to the materials chosen and manufacturing
processes used, RINGFEDER® Shrink Discs® can be tightened and
released as often as required. If locking screws need replacing, they
are standard items and thus easily available.

RINGFEDER® Shrink Discs®
Standard Series
Characteristics
Reduced dimensions with lower transmission values – especially
for applications with restricted space.
Simplified manufacture – only plain shaft and bore diameters with
easily achieved surface finish and tolerances are required.
Easy adjustability – No stops, steps, keyways, splines etc. are required, therefore hubs can be located and locked at any point or angle
on the shaft.
Easy mounting – RINGFEDER® Shrink Discs® use standard screws
and tightened using standard tools. No additional machining or fitting
work is required.
Easy removal – after loosening the locking screws, the
RINGFEDER® Shrink Disc® will self release and the hub will move
freely on the shaft.
Low susceptibility to contamination – when the locking screws are
tightened the contact (functional) surfaces are pressed firmly together
and prevent contamination by dirt and moisture.
Highest reliability – due to the materials chosen and manufacturing
processes used, RINGFEDER® Shrink Discs® can be tightened and
released as often as required. If locking screws need replacing, they
are standard items and thus easily available.

RINGFEDER® Shrink Discs®
split
Characteristics
Standard series – this range is the most popular, being used in most
applications. High transmission values are possible, and by varying
the screw tightening torque the Shrink Disc® can be adapted to the
design specification.
Simplified manufacture – only plain shaft and bore diameters with
easily achieved surface finish and tolerances are required.
Easy adjustability – No stops, steps, keyways, splines etc. are required, therefore hubs can be located and locked at any point or angle
on the shaft.
Easy mounting – RINGFEDER® Shrink Discs® use standard screws
and tightened using standard tools. No additional machining or fitting
work is required.
Easy removal – after loosening the locking screws, the
RINGFEDER® Shrink Disc® will self release and the hub will move
freely on the shaft.
Low susceptibility to contamination – when the locking screws are
tightened the contact (functional) surfaces are pressed firmly together and prevent contamination by dirt and moisture.

RfN 4073 Ultra Light Duty Series
RfN 4073
RINGFEDER® Shrink Discs®
Ultra Light Duty Series
Characteristics
Ultra Light Duty Series – this range is a very compact design with
low inertia values. It is ideally suited for mechanical seal and small
gearbox applications.
Simplified manufacture – only plain shaft and bore diameters
with easily achieved surface finish and tolerances are required.
Easy adjustability – No stops, steps, keyways, splines etc. are
required therefore hubs can be located and locked at any point or
angle on the shaft.
Easy mounting – RINGFEDER® Shrink Discs® use standard
screws and tightened using standard tools. No additional machining or fitting work is required.
Easy removal– after loosening the locking screws, the
RINGFEDER® Shrink Disc® will self release and the hub will move
freely on the shaft.
Low susceptibility to contamination – when the locking screws
are tightened the contact (functional) surfaces are pressed firmly
together and prevent contamination by dirt and moisture.

RfN 4091 Heavy Duty Series
RfN 4091
RINGFEDER® Shrink Discs®
Heavy Duty Series
Characteristics
Highest transmission values – for heavy duty applications.
Simplified manufacture – only plain shaft and bore diameters
with easily achieved surface finish and tolerances are required.
Easy adjustability – No stops, steps, keyways, splines etc. are required therefore hubs can be located and locked at any point or angle
on the shaft.
Easy mounting – RINGFEDER® Shrink Discs® use standard
screws and tightened using standard tools. No additional machining or fitting work is required.
Easy removal – after loosening the locking screws, the
RINGFEDER® Shrink Disc® will self release and the hub will move
freely on the shaft.
Low susceptibility to contamination – when the locking screws
are tightened the contact (functional) surfaces are pressed firmly
together and prevent contamination by dirt and moisture.
Highest reliability – due to the materials chosen and manufacturing
processes used, RINGFEDER® Shrink Discs® can be tightened and
released as often as required. If locking screws need replacing, they
are standard items and thus easily available.

RINGFEDER® Shrink Discs®
Standard Series
Characteristics
Standard series – this range is the most popular, being used in most
applications. High transmission values are possible, and by varying
the screw tightening torque the Shrink Disc® can be adapted to the
design specification.
Simplified manufacture – only plain shaft and bore diameters with
easily achieved surface finish and tolerances are required.
Easy adjustability – No stops, steps, keyways, splines etc. are required, therefore hubs can be located and locked at any point or angle
on the shaft.
Easy mounting – RINGFEDER® Shrink Discs® use standard screws
and tightened using standard tools. No additional machining or fitting
work is required.
Easy removal – after loosening the locking screws, the
RINGFEDER® Shrink Disc® will self release and the hub will move
freely on the shaft.
Low susceptibility to contamination – when the locking screws are
tightened the contact (functional) surfaces are pressed firmly together
and contamination by dirt and moisture.

RINGFEDER® stainless Products
Characteristics
Inexpensive manufacture – The large tolerances that are possible and the simple turning
process guarantee inexpensive manufacture.
Simple installation – Only a few screws need to be tightened, alignment to precise angles
between the hub and shaft is possible in any position, no fitting work is required.
Simple dismantling – Locking Assemblies RINGFEDER® are fitted with threaded extraction holes, so that no additional auxiliary equipment is necessary, series RfN 7012 is
self-releasing.
Large constant reverse-torsion fatigue strength – shaft and hub are ungrooved, so
that there is no weakening of these components. Shaft and hub can be designed to be
considerably smaller (lighter, cost and space-saving design possible).
No danger of deflection – Locking Assemblies RINGFEDER® are absolutely backlashfree.
Effect similar to overload protection – After the set frictional connection force has been
exceeded the Locking Assemblies simply slide. Valuable machine parts are protected.
The Locking Assemblies are subject to the same laws as any other connection with force
transmission by friction - not suitable as sliding clutch.
Completely maintenance-free – no follow-up costs.

Explanations to tables
d, D, L, l, L1, L2, d1 = Basic dimensions
Additional loads, e.g. tension, thrust or bending have to be
taken into consideration accordingly.
dW =solid shaft diameter (provided by the customer)
T
=transmissible torque
Fax =transmissible axial force
p =approx. surface pressure on the hub extension
(diameter d)
TA =required tightening torque per screw
(Screws greased with molykote!)
n
=quantity of screws
Function values
The functional characteristics are valid with the screw tightening torque listed in the tables and the following assumed
conditions:
The locking screws are lubricated using MoS2 (µtot= 0.1).
The tapered cones are lubricated using MoS2 (µ = 0.05).
The contact surfaces (dw ) are in lightly oiled condition with
coefficient of friction µ = 0.12.
The hub and shaft materials have a modulus of elasticity of
30 x 106 PSI. (Lower values­result in increased values for T
and Fax with reduced tangential stress.)
Tmax =maximum theoretical transmissible torque
Cw = shaft clearance
The maximum clearance is being fully utilized.
The shaft being used is solid, for hollow shaft applications
the functional values will change.
Ch = Hub tolerance
σv
=calculated combined stress in the hub extension (d/
dw) under consideration of the tangential, radial and
torsional stresses following the equation:
In cases where the assumed conditions do not apply then
contact our Technical Department where we will be happy to
assist you with your application.

RINGFEDER® Shrink Discs®
Standard Series stainless
Characteristics
Standard series – this range is the most popular, being used in
most applications. High transmission values are possible, and by
varying the screw tightening torque the Shrink Disc® can be adapted to the design specification.
Simplified manufacture – only plain shaft and bore diameters
with easily achieved surface finish and tolerances are required.
Easy adjustability – No stops, steps, keyways, splines etc. are
required, therefore hubs can be located and locked at any point or
angle on the shaft.
Easy mounting – RINGFEDER® Shrink Discs® use standard
screws and tightened using standard tools. No additional machining or fitting work is required.
Easy removal – after loosening the locking screws, the
RINGFEDER® Shrink Disc® will self release and the hub will move
freely on the shaft.
Low susceptibility to contamination – when the locking screws
are tightened the contact (functional) surfaces are pressed firmly
together and prevent contamination by dirt and moisture.

RINGFEDER® Smart-Lock
Smart-Lock-Set: the connection of the future
For the perfect hollow shaft connection, the solid shaft is
always manufactured to a high degree of precision, normally
with a dimensional tolerance of h6/H6. This close tolerance,
high-finish shaft is inserted into the equally close tolerance
hollow bore of the gearbox and secured in place by the compressive force of the Shrink Disc®. Only by maintaining the
strict dimensional tolerances the full torque capacity can be
reliability achieved.
Smart-Lock puts an end to all the precision machining involved and guarantees an optimum connection even with
clearances up to 0.2 mm (0.008 inches).
The flexibility offered by using interchangeable bushings
between the solid shaft and the hollow shaft of the gearbox
makes the Smart-Lock-Set an invaluable aid to the marketplace. Thanks to the availability of shaft adapter bushings
with various inside diameters, one gearbox can be used with
a range of shaft sizes without a change out of the shaft or
Shrink Disc®. The ease of selecting and using the SmartLock-Set is child´s play.
The Smart-Lock-Set is an efficient design that makes economic sense to the user. Not only can it compensate for larger
dimensional tolerances up to 0.2 mm (0.008 inches), it also
offers significant cost savings by requiring a minimal number
of spare parts needed in inventory. Furthermore, inexpensive, cold drawn, commercial available shafting up to quality
grade h11 can be utilized without additional machining. The
export market also benefits from using Smart-Lock-Set; adapter bushings in inch size standards are readily available
from local inventories for countries that don´t use metric
measurements. Expensive specials and large spare part inventories are a thing of the past.
68
Characteristics
Flexible, cost-saving, easy to maintain: Smart-Lock-Set is the new
Shaft/Hollow Shaft connection from RINGFEDER®. Cylindrical Bushings allow the attachment of hollow shaft gear reducers and other
hollow shaft connections to any metric and inch size solid shaft diameter.
• Reliable:
Tension-optimized and virtually indestructible Shrink Discs
guarantee the highest possible degree of safety
• Uncompromising:
Cylindrical Bushings for a wide range of shaft diameters
provide the perfect connection.
• Economical:
The Smart-Lock-Set requires minimal labor at installation
and reduces spare part inventory costs up to 70 %.
Technical details of the Smart-Lock-Set
For Gearbox manufacturers:
• Eight standard sizes of adaptor bushings are available for hollow
shaft outside diameters from 44 to 90 mm.
• The inside diameters are variable and accommodate the most
common metric and inch size shaft sizes.
• Commercially available solid shafting without any machining can
be used. Diameters from 25 to 70 mm are possible.
For users of Gearboxes:
• The torque to be transmitted is the criterion used to select the
shaft diameter.
• The optimum shaft size for an individual gearbox can be used
in connection with the Smart-Lock-Set.
• It is possible to standardize on a certain gearbox size for a range
of shaft diameters. The results are lower costs for maintenance
and spare parts.

RINGFEDER® Shaft Couplings
Characteristics
RINGFEDER rigid sleeve Couplings, type WK 5071 and WK 5091
have a proven track record in the industry. These Couplings are
pre-engineered with RINGFEDER Shrink Discs® to connect two
components rigidly and backlash free, when there is no misalignment between those components permitted.
Applications such has conveyor drives, ship drive shafts, line shafts
in steel mills, etc., are ideal applications for the standard and heavy
duty rigid sleeve Couplings.
Although our catalog shows some preselected standard length
sleeve Couplings, our technical staff can custom make a design
to fit your needs. We can provide special lengths, materials and
versions for every need. Please contact the nearest RINGFEDER
POWER TRANSMISSION OFFICE!

Function values
The functional characteristics are valid with the screw tightening torque listed in the tables and the following assumed
conditions:
The locking screws are lubricated using MoS2 (µtot= 0.1).
The tapered cones are lubricated using MoS2 (µ = 0.05).
The contact surfaces (dw ) are in lightly oiled condition with
coefficient of friction µ = 0.12.
The hub and shaft materials have a modulus of elasticity of
30 x 106 PSI. (Lower values­result in increased values for T
and Fax with reduced tangential stress.)
Tmax =maximum theoretical transmissible torque
Cw = shaft clearance
The maximum clearance is being fully utilized.
The shaft being used is solid, for hollow shaft applications
the functional values will change.

RINGFEDER® Shaft Couplings
Standard Duty Coupling
Characteristics
Three part Shrink Disc® heavy duty series – with additional
guide mechanism for the inner ring. For the transmission of maximum torques.
Highest reliability – applicable for static, dynamic and impact
loads.
Simplified manufacture – only plain shaft and bore diameters
with easily achieved surface finishes and tolerances are required.
Fully replaceable – the RINGFEDER® Shrink Discs® work
are self releasing.
Visual check of the tightening status – minimization of faults
during assembly.
Easy mounting – RINGFEDER® Shrink Discs® use standard
screws and tightened using standard tools. No additional machining or fitting work is required.
Short assembly times – cost savings particularly in the case of se‑
ries production.
Low susceptibility to contamination – when the locking screws
are tightened the contact (functional) surfaces are pressed firmly together and prevent contamination by dirt and moisture.
Easy adjustability – No stops, steps, key-ways, splines etc. are
required therefore, hubs can be located and locked at any point or
angle on the shaft.

Installation
Removal
1.Clean the area on the hub where the Shrink Disc® will be
seated and oil to ease assembly, if necessary.
1.Loosen the bolts evenly and in sequence, again in several
circular sequences, to avoid jamming of the discs on the inner
ring. Never completely remove the bolts from their threaded
holes, this creates a risk of accidents.
2.Removing spacers which may be present between the
thrust rings for transport purposes.
3.Sliding the Shrink Disc® onto the hub.
Attention: Do not start tightening the bolts before the shaft
is in the bore of the hub, as this may cause permanent
deformation.
2.Slide the Shrink Disc® and its attached part from the shaft.
Clean shaft and remove possible traces of rust from the
shaft.
4.Slide the hub onto the shaft and position as required. Use
a thin oil to lightly lubricate the hub bore and shaft to facilitate assembly.
Attention: Do not use lubricants containing MOS2.
5.Tighten 3 or 4 locking screws that are equally spaced
around the diameter to establish a parallel or perpendicular position of Shrink Disc® collar(s) relative to hub web
or shaft, respectively. This step properly seats the collar(s)
on the taper of the inner ring.
6.Using a torque wrench, tighten all locking screws gradually and in sequence all the way around (not in a diametrically opposite sequence). Several passes may be required
until all screws are torqued to the specified tightening
torque (TA).
7.Verify that the screws are completely tight by applying
the specified tightening torque (TA). The gap between the
Shrink Disc® collars or between the Shrink Disc® collar
and the hub should be even all the way around.

Installation
Removal
1.Clean the area on the hub where the Shrink Disc® will be
seated and oil to ease assembly, if necessary.
1.Gradually release the locking bolts all the way around. Begin
by releasing each bolt only about one quarter of a turn.
2.Sliding the Shrink Disc® onto the hub.
Attention: Do not start tightening before the shaft is in
the bore of the hub; this may cause permanent deformation.
2.If the Shrink Disc® does not loosen, back all screws out
until there is a gap between the head of the bolts and the
Shrink Disc® face.
3.Slide the hub onto the shaft and position as required. Use
a thin oil to lightly lubricate the hub bore and shaft to facilitate assembly.
Attention: Do not use lubricants containing MOS2.
3.Completely remove a few screws and thread them into
the adjacent removal threads roughly equally spaced
around the diameter. Use these fasteners to push the
inner ring away from the outer collar until the Shrink
Disc® is loose on the shaft.
4.Tighten 3 or 4 locking screws that are equally spaced
around the diameter to establish a parallel position of
the Shrink Disc® inner relative to outer ring. This step
properly seats the the taper of the inner ring.
5.Using a torque wrench, tighten all locking screws gradually and in sequence all the way around (not in a diametrically opposite sequence). Several passes may be required
until all screws are torqued to the specified tightening
torque (TA).
6.Verify that the screws are completely tight by applying the
specified tightening torque (TA).
• Assembly, using a torque wrench:
Check torquing of the bolts in sequence of their positions. Assembly is only complete once all the bolts have been torqued as specified.
• Assembly, without a torque wrench:
Assembly is complete once the faces of the inner and outer rings are aligned flush.

Removal
1.Clean the area on the shaft where the Shrink Disc® will be
seated and oil lightly to ease assembly, if necessary.
Attention: Do not use lubricants containing MOS2.
1.Loosen the bolts evenly and in sequence, again in several
circular sequences, to avoid jamming of the discs on the inner
ring. Never completely remove the bolts from their threaded
holes, this creates a risk of accidents.
2.Fasten the attachment part to the Shrink Disc®.
ATTENTION: Tighten the bolts lightly.
2.Slide the Shrink Disc® and its attachment part from the
shaft. First remove possible traces of rust from the shaft.
3.Slide the Shrink Disc® onto the shaft.
3.Release the attachment part from the Shrink Disc®.
4.Tighten 3 or 4 locking screws that are equally spaced
around the diameter to establish a parallel or perpendicular position of Shrink Disc® collar(s) relative to hub web
or shaft, respectively. This step properly seats the collar(s)
on the taper of the inner ring.
5.Using a torque wrench, tighten all locking screws gradually and in sequence all the way around (not in a diametrically opposite sequence). Several passes may be required
until all screws are torqued to the specified tightening
torque (TA).
6.Verify that the screws are completely tight by applying
the specified tightening torque (TA). The gap between the
Shrink Disc® collars or between the Shrink Disc® collar
and the hub should be even all the way around.
