The CSK One Way Bearing Series is a sprag type freewheel integrated into the 6200 radial bearing series. The internal part of the bearing is protected by a seal but additional seals are recommended especially when the working temperature exceeds 50ºC. All CSK One Way Bearings are equipped with chrome formed sprags that increases the over-run life several times. Torque transmission is ensured by a press fit assembly into a rigid outer housing and onto a shaft with an N6 tolerance. Initial bearing radial clearance is set at C5 and is reduced if using the press fit as specified.
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. In addition to the basic CSK model, type CSK..P features a keyway on the inner race and CSK..PP features a keyway on both the inner and outer race. For this reason it can be keyed to a shaft.
