20x47x14 sprag type clutch sealed one way bearing csk20 2rs
The CSK bearing 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.It has a small radial section height and is also commonly known as a one way bearing or anti reverse bearing. They 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.
