Airflex Airflex® CBC Clutch/Brake Combination Today’s answer for high cyclic, heavy-duty industrial applications. Authorized Distributor ® 26255 Groesbeck Hwy. Warren, MI 48089 U.S.A. 586.775.3000 • 586.775.3040 (Fax) [email protected] www.midwestbrake.com Eaton® Airflex® Clutches & Brakes CBC Clutch/Brake Combination The Airflex® CBC clutch/brake combina- tion consists of an air-actuated disc clutch and a spring-applied disc brake. Its compact design combined with its high thermal capacity and low air consumption makes it ideal for high speed, high cyclic, heavy-duty industrial applications. The CBC hub is pressed on and keyed to the driven shaft. The clutch disc is fastened to the driving member (a flywheel in most applications). The brake disc is reacted to the machine. Three different means of disc attachment results in five possible mounting arrangements. Operation is simple. When the cylinder is pressurized, the piston clamps the clutch disc to the hub, which transmits torque to the shafts. When the cylinder exhausts, the springs move the piston shaft. Overlapping cannot occur between the clutching and braking. Efficient cooling permits a stable coefficient of friction resulting in repro- Brake Disc ducible torque control. Minimal torque Clutch Disc loss combined with generous friction lining area results in low operating and maintenance costs. Piston CBC units are available in 14 standard sizes with clutch torque to 1,140,000 lb·in (129.000 N·m) and brake torque to Cylinder 529,000 lb·in (60.000 N·m).
