Air Clutch Mechanisms with Adapters - Heavy Duty


Through Shaft Bored, Adapter Mount Friction Clutch

Operation
  • Friction type heavy duty clutch mechanism 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 mechanism slides on shaft and is fixed with set screws and a customer supplied key
  • Adapter connects to a fully supported, bearing mounted pulley, gear or sprocket
  • Anti-rotation arm required to prevent rotation of the air housing
  • Heavy duty clutch mechanisms are designed for horizontal mounting. If vertical mounting is required, consult engineering for options
  • Note: Heavy Duty Clutch Mechanism DOES NOT support Adapter
Applications
  • Heavy duty clutch mechanisms are suitable for cycling applications connecting and disconnecting two fully supported shafts
  • 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
  • Machined face and bolt circle on adapter facilitate connection to a bearing mounted pulley or gear
  • Available with either high or low* coefficient friction linings for same price

*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 mechanisms are solidly constructed with splined drives and toothed friction to provide reliable power transmission. Heavy duty clutch mechanism 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 mechanism for use in a new or retrofit application.
