Air Engaged Clutches - Regular Duty, Under 200 RPM


Through Shaft Bored, Pilot Mount Friction Clutches

Operation
  • Friction clutch engages with air pressure, spring released when air is exhausted
  • Torque is linear in response to air pressure applied
Mounting
  • Through/Mid Shaft or End of Shaft
  • Clutch slides on shaft and is fixed with set screws and a customer supplied key
  • Anti-rotation arm required to prevent rotation of the air housing
  • Designed for horizontal mounting. If vertical mounting is required, consult engineering for options
Applications
  • Connect, Disconnect, Cycling
  • Limited to speeds up to 200 RPM. See Ball Bearing Pilot models for high speed applications
Design Features
  • Bored to suit up to the maximum shown (US & Metric) for easy installation
  • Available with either high or low* coefficient friction linings for same price
  • Machined pilot for easy mounting of pulley sprocket

*Low coefficient lining models are offered for applications where a small amount of slip is required or a narrower torque range is necessary. For continuous slip or tension control applications, a SensiFlex® clutch should be used.
