Pneumatic Drum Clutches & Brakes

The FKE is best suited for applications with light starting and stopping loads. It is also commonly used as a slip clutch or tension brake within light horsepower and torque applications.

The FKR is often referred to as a coupling, as its expanding neoprene rubber facing engages the interior diameter of the drum directly. The resulting friction generates significant torque within a small package. 

The FK is well suited as a clutch or brake for a variety of high speed and low to medium torque power transmission applications where high heat generation is not a factor.

The FKT is well suited for applications with the most demanding equipment where severe clutching and braking is required.

The FM is designed and manufactured for marine applications, mainly for use on diesel-driven reduction gears.
