BS...R Freewheel Backstop Clutch Bearings 

The BS-R Series Cam Clutch is utilized in scenarios necessitating consistent oil lubrication, dictated by either environmental factors or operational frequency. Incorporating an oil reservoir enhances the ease of upkeep for lubrication. Although the torque thresholds and maximum free-rotation speeds align with the conventional BS Series Cam Clutch, the additional oil volume contributes to reducing thermal accumulation, potentially prolonging the Cam Clutch's operational lifespan. 


For placing an order for a Cam Clutch with an Oil Reservoir feature, the letter "R" indicative of the reservoir is placed within the sequence of the Cam Clutch's model size and the bore dimensions as demonstrated below.
