Pilot Input 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 continous slip.
- Clutch is spring released when air is exhausted.
- Torque is linear in response to air pressure applied.
Mounting
- Through/Mid Shaft or End of Shaft.
- Anti-rotation arm required to prevent rotation of the air housing.
- Designed for horizontal or vertical mounting.
- Bored to suit up to the maximum shown (US & Metric) for easy installation.
Applications
- For tension control applications requiring the clutch to drive the shaft when engaged.
- Cooling sleeve rotates with the pilot mounted sprocket, pulley, or coupling at the speed of the drive input.
- If clutch will drive a pilot mounted sprocket, pulley, or coupling when engaged, or if the clutch will be used as a brake, see the SensiFlex® Shaft Input (SI) model.
- 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.
Customization Options
All Mach III products can be customized to meet the needs of your application.
