BS-HS Series Cam Clutch offers a higher strength/higher rpm option. Non-rollover cams are flanked by individual bearings on both sides. This series is identified by ""HS"" following the frame size number. Designed to provide inner race overrunning capability in one direction of operation, and engage the outer race when reverse rotation is experienced. Typically found on long incline conveyor systems, bucket elevators, and large pumping systems.

BS-HS Series Cam Clutch units are all manufactured on a made-to-order basis. When ordering, please specify bore size and keyway dimensions along with tolerances if available. Tsubaki includes the shaft key with your BS-HS Cam Clutch. If tolerances are not known, Tsubaki will produce per our standards. A complete Cam Clutch assembly typically includes the Cam Clutch, torque arm, shaft key, shaft end plate, and safety cover or oil reservoir. BS-HS Series Cam Clutches are pre-lubricated with grease prior to shipping.

When ordering, specify the required bore size, keyway dimensions, and special tolerance if needed.
