CBW Model – Clutch/Brake Reducer Unit

An electromagnetic clutch and an electromagnetic brake are mounted on the input shaft of the worm gear reducer, and power is output from the reducer.Power is transmitted via a belt drive from the V-pulley. Since the input V-pulley is standard equipment, installation is complete simply by connecting the drive unit to the belt and mounting the reducer. No tedious alignment or machining is required.
