A CSK series one way (direction) bearing consists of a standard ball bearing,
in-built special snap block and cage.
These bearings are widely used in hydraulic machinery, printing machines,
textile machinery and others. |  | | Model | Bore | Width | O.

| CSK | Description
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 0,3mm. The use of additional "nylos" type seals is recommended especially when the working temperature exceeds 50癈.
Oil bath lubrication is also possible if the original grease is first flushed out using a suitable solvent.
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.
One race may be glued. If both races are to be glued, performance will be reduced or a C3 bearing clearance will be necessary.
Operating temperature range : -20癈 to +100癈. Peaks up to +120癈 are acceptable for short periods. Please contact us for higher temperatures.
In addition to the basic CSK model, type CSK..P features a keyway on the inner race. For this reason it can be keyed to a shaft to k6 tolerance. The outer race must still be pressed into a rigid housing to N6 tolerance. CSK..PP features a keyway on both the inner and outer race. The recommended mounting tolerances are h6 on the shaft and H6 in a rigid housing.
CSK..2RS is 5 mm wider but is equipped with lip seals to be water splash resistant. | | |
