Double Single Sprocket Clutch-Brakes To Stop and Start the Shaft

Combination Air Applied Clutch and Spring Applied Brake

Function: Starting and Stopping / Holding The Shaft
Drive Arrangement: Pilot Mounted Component to Shaft

Operation

  • Applying air pressure releases the spring applied friction brake and engages the friction clutch.
  • Torque of the clutch is linear in response to air pressure applied above the brake release pressure.
  • Brake torque is fixed by spring pressure.

Mounting

  • Through (Mid) Shaft or End of Shaft.
  • Clutch Brake slides on shaft and is fixed with set screws and a customer supplied key.
  • Anti-rotation arm required to react, brake, and prevent rotation of the air housing.
  • Clutch Brakes are designed for horizontal mounting. If vertical mounting is required, consult engineering.

Applications

  • Zero pressure accumulating conveyor systems.
  • Input through daisy chained sprockets.
  • Maximum RPM varies by model and is listed on the PDF detail sheet (see table below). Consult engineering if the intended application exceeds the listed maximum RPM.

Design Features

  • Clutch and brake combined in one unit for simplified mounting and control.
  • Clutch brakes are bored to suit up to the maximum shown (US & Metric) for easy installation.
