Spring Engaged Clutch – End of Shaft
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
Bore Sizes to 3.500 inch, Torque Requirements to 24,327 lb.in.
Clutch is blind bored and keyed for connection in an end of shaft location.
A sprocket, pulley or v-belt sheave can be mounted on the clutch pilot.
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.
