The Eaton Airflex CB element assembly is air-actuated, with a neoprene rubber air tube providing the clamping force. Friction shoes mounted on the tube’s inside diameter engage around a cylindrical drum. In this design, the rubber air tube is bonded to the outer steel rim.
Torque range: 360 to 260,000 lb-in (41 to 29,400 Nm)
Typical applications: Metal forming, printing, oil and gas, rubber processing
The Eaton Airflex VC element assembly is an air-actuated constricting drum unit. The VC’s ventilated design allows rapid heat dissipation. The torque is carried by torque bars, and leaf springs retract the friction shoes when air pressure is released. Because of this construction, all components are available as replacement parts when refurbishing the unit.
Torque range: 27,000 to 3,660,000 lb-in (3,050 to 413,057 Nm)
Typical applications: Grinding mills, marine propulsion, metal forming machinery
