AIR COOLED DISC CLUTCHES & BRAKES
Airflex DB Spring-Applied Brakes are disc style brakes that are spring-applied and air-released. The DBB torque capacities and heat dissipation characteristics make them ideal for high speed cyclic applications. The DBA and DBBS designs are ideal for non-cyclic applications because of their high energy capacities.
Airflex DC Clutches & Brakes are air-applied units available in multiple-disc designs. They feature a favorable torque to size ratio and low inertia friction disc assemblies.
Air cooled element brake sizes are indicated by the number of brake/friction discs and the disc diameter in inches. For instance, a size 229DBA has two discs 29 inches in diameter.
