Introduction

Type CSK is a sprag type freewheel integrated into a 62 series ball bearing 

(except sizes 8 and 40). It is bearing supported, delivered grease lubricated and 

protected against dust of more than 0,3 mm. The use of additional "nylos" type seals is 

recommended especially when the working temperature exceeds 50°C. Oil bath lubrication

 is also possible.
All the CSK versions are equipped with "form chromed" sprags. This process increases 

several times the overrunning life time. Torque transmission is ensured by a press fit 

assembly into a rigid outer housing with N6 tolerance, and onto a shaft with n6 tolerance.

 The initial bearing radial clearance is set at C5, and is reduced if using the press fit as specified.
Please contact us when either the ambient or the operating temperature is not within the range +5°C

Applications Reducers , Flender Gearbox ,SEW Gearbox;
Overrunning clutch:for multiple-machine drives or to separate the inertia of masses of a driven machine from the driving
machine after it has been switched off.

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

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