Gummi Constricting Air Clutches & Brakes

Gummi Constricting Clutches and Brakes are drum-type elements that radially engage the outer diameter of a drum when pressurized.The inward expansion of the rubber nylon cord-reinforced air tubeforces the element’s friction shoe assemblies against the outer diameter of the drum’s surface. The rate at which the air tube is pressurized directly affects the rate at which the torque increases.
