Air Engaged Clutches - Heavy Duty


Through Shaft Bored, Pilot Mount Friction Clutches

Operation
  • Friction type heavy duty 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
  • Heavy duty clutch slides on the shaft and is fixed with set screws and a customer supplied key
  • Anti-rotation arm required to prevent rotation of the air housing
  • Heavy duty clutches are designed for horizontal mounting. If vertical mounting is required, consult engineering for options
Applications
  • Heavy duty 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
  • Heavy duty clutches are bored to suit up to the maximum shown (US & Metric) for easy installation
  • Splined drive and toothed friction discs for heavy duty service
  • Available with either high or low* coefficient friction linings for same price
  • Machined pilot for easy mounting of pulley or 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.

Additional Information

Mach III heavy duty clutch units are solidly constructed with splined drives and toothed friction to provide reliable power transmission. The clutch pilot is machined for easy mounting of a sprocket or pulley in the field, or, Mach III can provide a sprocket, pulley or v-belt sheave pre-mounted on the heavy duty clutch when it ships from our factory. Heavy duty clutch models can be adapted to accommodate customer needs. See our Custom Design Solutions page for more information. Mach III encourages contact with our engineering department before purchasing a heavy duty clutch for use in a new or retrofit application.
