Type CB for Tyre Building Machine –

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. Torsional resilience is provided by transmitting power through the side walls of a flexible neoprene/cord actuating tube. This flexibility also permits minor shaft misalignment.
