Tension Control Brakes

• Friction brake engages with air pressure and is designed for continuous slip.
• Brake is spring released when air is exhausted.
• Torque is linear in response to air pressure applied.

Mounting

• Flange bolts to machine frame or other fixture, shaft inserts into bore and is fixed with set screws and customer supplied key.
• Designed for horizontal or vertical mounting.

Applications

• For applications requiring a brake to provide tension on and/or stopping of an unwind shaft.
• Cooling sleeve rotates at speed of unwind shaft.
• Maximum RPM varies by model. Please consult the detail sheets (below). Consult engineering if the intended application exceeds the listed maximum RPM.

Design Features

• Exclusive, patented actuator engages smoothly at low pressures and provides maximum sensitivity to slight changes in air pressure for infinite control of torque output.
• Radial cooling holes pull cooler, ambient air through the clutch or brake to dissipate the heat generated by constant slip, preventing friction lining fade and premature wear.
