Pilot Input Clutch-Brakes To Stop and Start the Shaft - Mach III

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 for options.

Applications

Stop/Start, Cycling, Indexing with input from a constantly driven sprocket or pulley.
For applications with small brake torque requirement.
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.
Machined pilot for easy mounting of pulley or sprocket.

Customization Options

All Mach III products can be customized to meet the needs of your application.
