Fearures of sprag one way clutch bearings
The CSK One Way Bearing Series has a small radial section height and is also commonly known as a One Way Bearing or Anti-Reverse Bearing. One Way Bearings are designed to transmit torque between the shaft and housing in one direction and allow free motion in the opposite direction.
CSK Clutches are typically special machine elements:
When rotating in one direction, there is no contact between the inner and outer rings, i.e. the one-way clutch is free to rotate.
When turning in the other direction, the inner and outer rings are in close contact, and the one-way clutch can transmit high torques.
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. Please contact us when either the ambient or the operating temperature is not within the range +5°C to +60°C.
