Product Guide for Eaton Airflex Expanding Drum Type Clutches & Brakes

Type EB

BrakeTechnique®, Inc. Products
Torque capacities up to:
98,580 lb-in
11.130 N-m

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.


Type VE

BrakeTechnique®, Inc. Products
Torque capacities up to:
221,000 lb-in
24.950 N-m

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.


Type E

BrakeTechnique®, Inc. Products
Torque capacities up to:
1,010,000 lb-in
114.000 N-m

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 in shoe disengagement and counteract the centrifugal force.


Type ER

BrakeTechnique®, Inc. Products
Torque capacities up to:
118,000 lb-in
13.300 N-m

Airflex ER couplings are expanding units with neoprene facing. As such, they combine the advantages of a flexible and disconnect coupling. Engagement of the element should occur when there is no speed differential between driving and driven shaft.
