Shaft Input Clutch-Brakes To Stop and Start the Pilot
Combination Air Engaged Clutch – Spring Engaged Brake
Function: Starting and Stopping / Holding The Pilot Mounted Component
Drive Arrangement: Shaft to Pilot Mounted Component
- 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.
- 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. Consult engineering if vertical mounting is required.
- Stop/Start, Cycling, Indexing with input from constantly turning shaft.
- 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.
- 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.
- Machined pilot for easy mounting of pulley or sprocket.
