It is self-contained dust protected unit, delivered grease lubricated.
Nominal outside dimensions are the same as a 60.. series bearing. Torque transmission must be ensured by a press fit on both the inner and outer race. Because of this press fit, the standard radial clearance is C4. The interference tolerances are on the freewheel dimensions, allowing a direct mounting in a standard series 60.. bearing location: Shaft tolerance should be h6 or j6 The outer race should be pressed into a rigid housing to K6 tolerance.
Radial bearing load capacities are given in the table. Type ASK freewheels cannot accept axial loading. In cases of such loads, thrust bearings must be provided.

CSK and CSK..2RS | Stieber Clutch
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 “nylons” 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 “formchromed” sprags. This process increases several times the overrunning lifetime. Torque transmission is ensured by a press fit assembly into a rigid steel housing with N6 tolerance, and onto a shaft with n6 tolerance. For this reason, the initial bearing radial clearance is set at C5.
Please contact us when either the ambient or the operating temperature is not within the range +5°C to +60°C. CSK..2RS is 5 mm wider but is equipped with lip seals to be water splash resistant.
