High speed and low noise 8x22x9 CSK miniature one way bearing CSK8 without keyway
CSK8 one way (clutch) Bearing .The CSK series is a one way (clutch) ball bearing.One way Bearing Sprag/Clutch Freewheel and also called as Backstops.It is a sprag type freewheel integrated into a 62 series ball bearing(except sizes 8 and 40). They 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 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.
