Spring Engaged Clutch – 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

Operation

  • Industrial friction clutch is engaged with spring pressure.
  • A fixed amount of torque is transmitted.
  • To release clutch, air pressure is applied to overcome the spring pressure.

Mounting

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

Applications

  • Spring engaged friction clutches are suitable for applications requiring the clutch to remain engaged in the absence of air pressure or during a loss of power.
  • Not suitable for 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 for easy installation.
  • Machined pilot for easy mounting of pulley or sprocket.
  • Includes rotary air seal.
