Air Engaged Clutches - End of Shaft

Air Engaged Clutches – End of Shaft

End of Shaft Bored, Pilot Mount Friction Clutches

Function: Connect, Disconnect
Drive Arrangement: Shaft to Pilot Mounted Component or Pilot Mounted Component to Shaft


  • Industrial friction clutch engages with air pressure, spring released when air is exhausted.
  • Torque is linear in response to air pressure applied.


  • End of Shaft.
  • Friction clutch slides on shaft and is fixed with set screws and a customer supplied key.
  • No anti-rotation arm required.
  • Friction clutches are designed for horizontal mounting. If vertical mounting is required, consult engineering for options.


  • Friction clutches are suitable for Connect/Disconnect and Cycling applications.
  • Maximum RPM varies by model. Please consult the detail sheets (below). Consult engineering if the intended application exceeds the listed maximum RPM.

Design Features

  • Industrial friction clutches are bored to suit up to the maximum shown (US & Metric) for easy installation.
  • Low coefficient friction lining versions are available for applications requiring slip or a narrower torque range. Contact engineering for details.
  • Machined pilot for easy mounting of pulley or sprocket.
  • Includes rotary air seal.
