Constricting Clutches & Brakes

Constricting Clutches & Brakes

Airflex Constricting Clutches & Brakes are drum style products that when pressurized, expand radially inward, forcing their friction shoes against an outer cylindrical drum surface. The rate at which the tube is pressurized determines the rate at which element torque increases. Final tube pressure determines the element torque capacity.

Product Sizing

Constricting elements are identified by the drum diameter in inches on which they constrict and the width in inches of their friction lining. For instance, a size 26CM475 is designed to constrict on a 26 inch diameter drum and has a friction lining width of 4.75 inches.
