Pneumatic Combination ClutchBrake comprises of a clutch & spring applied Disc Brake which is air actuated. The Clutch Brakes are intricately designed. It has the twin attributes of high thermal capacity & low air consumption which makes it ideal for high speed, high cyclic, heavy-duty industrial application. 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. The totally cancels out overlap of clutch & Brakes. The clutch brake are housed in a hub which is pressed & keyed to the driven shaft. These plates can be suspended on twelve pins & guide bushes or on two coaxial or non-coaxial bolts.
