CB Clutches and Brakes

Available from Clutch Engineering, the Eaton Airflex CB element assembly is useful for integrating with metal forming equipment, printing systems, oil and gas equipment, and rubber processing plants. The product is air-actuated, with an integrated neoprene rubber air tube that provides the necessary clamping force. The torque lever arm is the drum radius, not a reduced radius as occurs in plate clutches. There are friction shoes mounted on the tube's inside diameter, and they engage around a cylindrical drum when in operation. In this design, the neoprene rubber air tube is bonded to the outer steel rim. Airflex constricting elements concentrate the frictional force on the outside drum diameter, which functions to achieve maximum torque. Not only is the force generated at the optimum radius, it is also applied uniformly around the drum circumference. Torque range: 360 to 260,000 lb-in (41 to 29,400 Nm) Typical applications: Metal forming, printing, oil and gas, rubber processing
