The BS Series Cam Clutch devices are designed to allow the inner race to freewheel in one direction and engage the outer race when rotation in the opposite direction is detected. These products are often used in applications like sloped conveyors or pump systems that may experience reverse rotation due to high loads on the pump's output end. The BS Series Cam Clutches incorporate a cam and roller mechanism with a low-friction bearing within the cam cage for enhanced efficiency.
