Expanding Clutches & Brakes
Airflex Expanding Clutches & Brakes utilize a rugged tire-like neoprene and cord tube that expands radially outward when pressurized. The expanding tube forces a friction surface against an inner cylindrical drum surface. The rate at which the tube is pressurized determines the rate at which element torque increases. Final tube pressure and rotating speed determines the element torque capacity.
Product Sizing
Expanding elements are identified by the inside drum diameter in inches to which they expand and the width in inches of their friction lining. For instance, a size 16E475 is designed to expand to a 16 inch diameter drum and has a friction lining width of 4.75 inches.

E
Airflex E elements are primarily used as slip clutches or tension brakes; however, they can also be used for general power transmission service.
EB
Airflex EB element assemblies are used in both clutch and brake service with light starting loads. The EB is similar in design to the CB except that it is an expanding type unit.
VE
Airflex VE elements were specially designed for greater heat dissipation capacity in an expanding type element. Available in a limited number of sizes, they offer all of the type E features.
