Product Details

We provide a range of drum style pneumatic clutches and brakes, both constricting and expanding types, in six clutch/brake configurations that are fully interchangeable with all other clutch brands in the market today.

All our drum brakes and clutches feature an integrated nylon cord reinforced neoprene tube. The final tube pressure determines the element's overall torque capcacity, and the rate at which the air tube is pressurized directly affects the rate at which the toque increases.

The tables below show the range of clutches, sizes and powers we have available. For more details, or if you would like help to make a size selection for a new or replacement element, please contact with us.
