KHS Drawn cup needle roller clutches have a very small radial section height and makes optimum use of the available space allowing compact designs to be achieved. These clutches are suitable for transmitting high torque and are normally used for indexing ,back-stopping and as overrunning clutches. HF and RC series are composed of thin-walled drawn outer ring with a series of ramps on its inside diameter and steel springs in the plastic cage. Needle rollers, which are retained and guided by a plastic cage, form the clamping elements. HFL and RCB series has two integral radial bearings arranged on both sides of needle roller clutch and can therefore support radial forces in particularly space-saving bearing arrangements. (series includes HF,HFL,RC,RCB ..etc.)
