Drawn cup needle roller clutches have a smallest radial section height among all clutches. This makes optimum use of the available space and allows compact designs. These clutches are suitable for transmitting high torque. They are normally used for converters, non-return devices and transcendental clutches. HF series is composed of thin-walled drawn outer ring and plastic cage. There are 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 series has two integral radial bearings arranged on both sides of needle roller clutch. They can therefore support radial forces in particularly space-saving bearing arrangements.
