TENSION CONTROL BRAKES SensiFlex® Patented Tension Control Technology Engineered to deliver precision control of web tension without sticking, pulsing or cogging. Operation 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. 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.
