Spring Engaged Clutch – Through Shaft
AIR AND SPRING ENGAGED FRICTION CLUTCHES
Available with either air or spring engagement and in an array of mounting options, friction clutches from Mach III transmit torque from one drive train component to another. They are used to connect and disconnect machine components.
SPRING ENGAGED CLUTCH – THROUGH SHAFT
Through 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 23,733 lb.in.
- Clutch is through bored and keyed to connection to a shaft in any axial location.
- A sprocket, pulley or v-belt sheave can be mounted on the clutch pilot.
Operation
Friction clutch is applied with spring pressure.
A fixed amount of torque is transmitted.
To release clutch, air pressure is applied to overcome the spring pressure.
Mounting
Through Shaft/Mid Shaft or End of Shaft.
Spring applied friction clutch slides on shaft and is fixed with set screws and a customer supplied key
Anti-rotation arm required.
Clutch is designed for horizontal mounting. If vertical mounting is required, consult engineering for options.
Applications
Spring applied 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
Made to order, bored to fit the shaft size you specify up to the maximum shown for easy installation.
Machined pilot for easy mounting of pulley or sprocket.
