Drawn cup needle roller 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. RC,RCB are inch series.
NOTE: HFL series are available upon request.
