Airflex® Clutches & Brakes A complete line of quality clutches and brakes for industry catalog 900 Powering Business Worldwide

History and Development Early interest by Thomas L. Fawick in the use of elastomers to solve industrial problems led to the development of the Fawick®Airflex clutch and the founding, in 1938, of the Fawick Company. The Airflex clutch is a unique drum type design which transfers torque through the sidewalls of a rubber-and-cord air actuating tube. Besides transmitting torque, the tube serves as a flexible member between the driving and driven shafts. Simplicity in design and operation are its other outstanding features. During the early 1940’s, after many applications on tugs and tow boats,...

Constructing Type Clutches and Brakes Section B Type CB Torque capacities up to: 1,160,000 Ib•in 131.000 N•m Airflex CB element assemblies are used as both clutches and brakes in general power transmission service. The primary feature of the CB design and construction is the Airflex torsional resilient principle made possible by the transmission of power through the side walls of the flexible neoprene and cord actuating tube. This flexibility also permits minor shaft misalignment. Type VC Torque capacities up to: 13,877,000 Ib•in 1567.000 N•m Airflex VC element assemblies are designed and...

Constructing Type Clutches and Brakes Airflex E elements are primarily used as slip clutches or tension brakes; however, they can also be used for general power transmission service. Torque is transmitted from the friction shoes to the element housing through torque bars. Engagement occurs when air expands the actuating tube forcing the friction shoes against the inside diameter of the drum. Release springs assist shoe disengagement and coun- teract centrifugal force. Airflex VE elements were specially designed for greater heat dissipation capacity in an expanding type element. Available in...

Water-Cooled Brakes Airflex WC air applied and spring applied water cooled brakes are designed for applications requiring high horsepower absorption. Its design incorporates copper alloy wear plates which transfer heat rapidly to circulating water. They are used for heavy-duty braking and tensioning applications, such as those found in metal and paper processing, as well as for cable tension control on logging, marine mooring and winch- ing equipment. The unit can also be used as an absorption Type WCSB Type WCSB Airflex WCSB is an air applied, water and air cooled multiple disc...

Air Cooled Disc Clutches and Brakes Section E Type DBA Static torque capacities up to: 386,630 lb•in 43.050 N•m Airflex DBA disc style brakes are spring-applied and air or hydraulically released. Its torque capacities and heat dissipation characteristics make it ideal for high speed cyclic applications. Equal torque is developed in either direction of rotation. Type DBB Static torque capacities up to: 2,535,750 lb•in 286.524 N•m Airflex DBB disc style brakes are spring-applied and air or hydraulically released. Its torque capacities and heat dissipation characteristics make it ideal for...

Clutch/Brake Packages Press Application Clutch/Brake and Control Airflex Press Application packages feature drum type CB or VC air applied clutches fastened to standard bearing-mounted flywheels. These clutch/flywheel assemblies are then com- bined with drum type CS and CTE or disc type DBA spring- applied, air released brakes. Although designed primarily for punch press use, they have found application on all types of cyclic equipment. Clutch/Brake Combination The Airflex CBC unit combines an air actuated disc clutch and spring-applied brake into a compact package, which can be readily...

Spring Applied Drum Brakes Section G Type CS Static torque capacities up to: 19,800 lb•in 2.235 N•m Airflex CS drum style brakes are spring-applied and air released. It automatically engages should an air or electrical loss of power occur. The brake is unidirectional, developing less torque in the reverse direction of drum rotation. Type CTE Static torque capacities up to: 108,350 lb•in 12.200 N•m Airflex CTE drum style brakes are spring-applied, air released and develops greater torque than Type CS. Its design and construction are ideal for moderate speed, high torque, cyclic applications....
