Oil or grease lubrication

Delivered with corrosion protection.

Operative grease filling on request.



Installation tolerances

Shaft h5; hub H6

Inner ring/shaft

steel, HRC 60+4 (HV 700+100); Ehd ≥ 1.3 mm; Rz ≤ 2.5 μm

Outer ring/housing

steel, HRC 60+4 (HV 700+100); Ehd ≥ 1.3 mm; Rz ≤ 2.5 μm



The freewheel clutch insert element requires axial constraints on both sides.


Mating parts

Hardening and grinding of the mating parts is not necessary. Thoroughly clean (grease free) the mating parts in the vicinity of the freewheel clutch as well as the freewheel clutch's rings before making the press fit.



Freewheel clutch insert elements are not self-centering.

External bearing support to define the gap between mating parts

(inner and outer rings) is necessary.

The specified nominal torque is based on sufficient stiffness of mating parts.

Rotation speed n = insert element's inherent speed.


Freewheel-clutches transmit or support torque moment by friction contact in one direction and permit idling in the opposite direction.
Freewheel-clutches are used as:
Indexing elements to change from oscillating to intermittent rotary motion.
Backstops to prevent self reversing due to load condition when the machine is not activated.
Overrunning clutches to maintain driven unit activated even during slowdown, or in the case of two speed operation
(by independent motors) to switch to the higher speed by passing the slower.
A large quantity of freewheel-clutches with varying design features and dimensions are available, depending on requirements such as: Torque, indexing frequency, idling speed and environment.
The supporting equipment around the clutch has to be built accurately and of high quality for the clutch to operate properly This is why we offer support units or complete assemblies of freewheel clutches.
Lubrication is especially important to obtain maximum life of freewheel clutches.
Good lubrication decreases drag. Please refer to our Lubrication Selection Table for proper selection.
Clutches (except the sealed
Clutches of series FND, FPD, FK 62...-RS, FK 62...-2RS, FKN...-RS
And FKN...-2RS) are shipped rustprotected not lubricated.
For extreme applications, please consult with our technical staff.

Changzhou RenBen Bearing Factory(Changzhou Global Bearing Factory)is a manufacturer specialized in Producing Various cam clutch, one way bearing, needle roller bearings,one way clutch, backstop clutch, overrunning clutch and other bearings with high technology.




Testing equipment



Main products


1. One Way Bearing

1. Overrunning clutch

for multiple-machine drives or to separate the iner-tia of masses of a driven machine from the driving machine after it has been switched off.

2. Indexing clutch

which turns a shaft step by step, thus achieving indexed material feed or a variable speed.

3. Backstop

to prevent a machine shaft turning backwards. In this case the overrunning clutch acts as a brake


2.Needle roller bearings





A Backstop application is where rotation

is allowed in one direction and stopped in

the opposite.

Application examples:

· Conveyor equipment

· Mixers

· High voltage switches

· Furniture industry

· Turnstiles and revolving doors

· Geared motors

· Winches

· Elevators

· Cranes

· Strap/belt tighteners

· Bucket conveyors

· Belt reversing locks

· Fans

· Automatic doors (subway)

· Fire damper flaps

· Aviation technology

· Roller plants

· Summer skiing


Indexing clutch

A repeated drive then idle motion will

be transferred to the driven side, step by

step, as rotary motion in one direction (the

clamping direction).


Application examples:

·Paper processing (advance)

· Seeding machines

· Staplers (staples)

· Conveyor belts (drive)

· Ratchets

· Ratchet wrenches

· Roller advance

· Installation tools

· Automation technology



Overrunning clutch

If the speed of the driven side exceeds the

speed of the driving side,the freewheel-clutch disengages the driving and driven sides by switching from torque transimit to idle.

Application examples:

·Copier machines

· Printing machines

· Conveyor equipment

· Transport equipment (speed matching)

· Starters for combustion engines

· Ergometers

· E-bikes

· Bicycle hubs

· Starters

· Emergency power aggregates

· Generators

· Hybrid applications (E-mobility)

· Palletizing and storage systems

· Model helicopters

· Hand operated sirens

· Roller coasters

· Washing systems

· Continuous ovens

· Compressors

· Compensating gearboxes

· Gas turbine drives

· Pump drives

· Belt drives

· Wheelchairs

B:We enjoy to grow up together with all our clients whatever big or small.And WIN-WIN is our objective.


A:Could you accept OEM and customize?
B:YES, we can customize for you according to sample or drawing, but, pls provide us technical data, such as dimension and mark.

A:Is it your company is factory or Trade Company?
B:We have our own factory; our type is factory + trade.

A:How to maintain my bearings?
B:a. Soak your bearings in mineral spririts or paint thinner to remove any grease or particulates;
b. Blowbearing out with compressed air; a light drop of oil on the bearing;
d.If the bearings feel rough repeat, give the bearing a spin.

A:Could you supply door to door service?
