The Clutch/Brake combination unit consists of an air actuated disc clutch & spring applied Disc Brake. Its compact design combined with its high thermal capacity & low air consumption makes it ideal for high speed, high cyclic, heavy-duty industrial applications.
When cylinder is pressurized, the piston clamps the clutch disc to the hub which transmits the torque to the shaft. When cylinder exhausts, the springs moves the piston in the opposite direction clamping the brake disc & stopping the shaft.
