An ending designation or suffix in the part number of KF indicates plastic springs and no suffix indicates stainless steel springs. Suffix of R indicates a partially knurled outer ring. Bore sizes are available in a range of 6mm to 35mm. A drawn cup needle roller clutch 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.
