Renold REGL Series Trapped Roller Freewheels are self-centring by means of a pair of 160 series ball bearings. Torque is transmitted to the inner race via a key and the outer race by means of bolts.
Components mounted onto the outside diameter of the outer race should be bored to an H7 tolerance. Shaft tolerance must be h6. The REGL is the base unit of the modular system. It is supplied with two paper gaskets for use between outer race and sealing cover/fixing plates.
