Gummi Expanding Air Clutches & Brakes

Gummi Expanding Air Clutches & Brakes

Gummi Expanding Clutches and Brakes are drum-type elements that expand radially towards the inner diameter of the drum when pressurized. The outward expansion of the rubber heavy-duty nylon cord reinforced neoprene tube thrusts friction shoes against the inner diameter of the drum surface. The rate at which the air tube is pressurized directly affects the rate at which the torque increases. Final tube pressure determines the element’s overall torque capacity.
