Heavy Duty Flexible Clutch Couplings 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 Set screws and customer supplied key connect the heavy duty clutch mechanism to one shaft and the coupling hub to a fully supported second shaft 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 flexible coupling 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 Elastomeric element compensates for up to 3 degrees of angular misalignment and up to 0.040 parallel offset between shafts Both heavy duty clutch mechanism and coupling bored to suit up to the maximum shown (US & Metric) to accept differing shaft sizes Available with either high or low* coefficient friction linings for same price Splined drive and toothed friction discs for heavy duty service

*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.

All Mach III heavy duty clutch mechanism with flexible coupling units are solidly constructed with splined drives and toothed friction to provide reliable power transmission from one fully supported shaft to another. Heavy duty clutch mechanism with flexible coupling 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 with flexible coupling for use in a new or retrofit application.
