Renold REUS Series Trapped Roller Freewheels are non self-centering. Bearings must be placed adjacent to the freewheel to ensure concentricity between inner and outer races.
The REUS Series freewheels have the same outside dimensions as standard 62 series bearings.
Torque is transmitted to the inner race via a key and the outer race by means of an interference fit. If the face keys in the outer race are used for torque transmission the housing tolerance should be H7 to provide a press fit. The housing must be strong enough to accept the stresses from the interference. Shaft tolerances must be h6/j6.
Prior to use, the freewheel must be lubricated. Oil lubrication is essential for over running applications.
The REUS is an open design so sealing must be provided by the installation.
