Friction Clutch-Brakes

Conveniently packaged clutches and brakes for start and stop applications. Clutch-brake combinations have mounting features that make them adaptable to NEMA and IEC motor frames and operate on static air pressure.

Shaft Mounted Clutch-Brakes

Hollow bore, shaft mounted clutch-brakes combine the features of a friction clutch and friction brake into a single unit.

Available with a pilot surface to mount sprockets or sheaves or with various integral sheaves. Available with a single piston that eliminates simultaneous clutch and brake engagement for transmitting motor torque up to 20 horsepower. Couplings are available for inline shaft applications.

ISO B5 Flange Clutch-Brakes

Available with air-engaged clutches and air or spring-engaged brakes. Can be ordered in open housing for the highest thermal performance or enclosed with black oxide, painted, nickel-plated, or nickel-plated BISSC (food grade) versions for challenging environments. Can be directly mounted to IEC B5 C-faced motors and/or reducers or free-standing foot mount with optional input units and feet. Other options include a locking key and an integral valve. Single-piston designs allow very high cycle rates with no chance of clutch-brake overlap problems.

Foot Mount Oil Bath Clutch-Brakes

Foot Mount Oil Bath Clutch-Brakes are designed for the most demanding applications. Oil carries heat away from the friction interface and extends life. Select models allow for an external cooling system to be added to increase thermal performance dramatically.


Nexen’s Friction Clutch-Brakes are ideal for applications that require:

  • Accurate Positioning
  • Controlled Acceleration
  • Controlled Deceleration
  • Cycling/Positioning
  • Disconnect
  • Inching/Jogging
  • Stopping/Holding
  • Tension Control
  • High inertia start/stop
