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.
