Foot Mount Tension Control Clutches

SensiFlex® Patented Tension Control Technology

Engineered to deliver precision control of web tension without sticking, pulsing or cogging.

Operation

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

Mounting

  • Foot brackets attach to machine frame or other fixture.
  • Pulleys or sprockets mount to the clutch’s input and output shafts.
  • Designed for horizontal or vertical mounting.

 

Applications

  • For tension control applications requiring input and output shaft connections.
  • Clutch drives output shaft when engaged.
  • Input shaft and cooling sleeve rotate at the speed of the drive input.
  • 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.
