    Air-Air Clutch-Brakes To Stop and Start the Shaft

    COMBINATION CLUTCH-BRAKES

    Mach III combination clutch-brakes provide both clutch and brake functions in one simple to install unit. When the clutch portion of the unit is engaged, power is transmitted from a source such as a continuously rotating motor to a machine component such as a shaft. When the brake is engaged, the component is held stationary.

     

    AIR-AIR CLUTCH-BRAKES TO STOP AND START THE SHAFT
    Combination Air Applied Clutch and Air Applied Brake

     

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

     

    Two separate air signals are required.
    Both clutch and brake torque transmitted are proportional to the amount of air pressure applied

    Operation

    Applying air pressure engages the friction clutch or friction brake. Each requires a separate air signal.
    Torque of the clutch and brake is linear in response to air pressure applied.

     

    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 similar clutch and 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 within the ranges shown on each product’s detail sheet (Imperial & Metric) for easy installation.
    Machined pilot for easy mounting of pulley or sprocket.
