Brake Sprag Clutch Freewheels

Renold REUS series trapped roller freewheels are non-self-centering, meaning a bearing must be placed next to the freewheel to ensure proper concentricity between the inner and outer races. The REUS series freewheels maintain the same outer dimensions as standard 62 series bearings. Torque is transmitted to the inner race via a key, while the outer race is driven by an interference fit. When using face keys in the outer race for torque transmission, the housing tolerance should be J6 to achieve a press fit. The housing must be robust enough to withstand the stresses caused by the interference fit. The shaft tolerance must be H6/J7.
