Clutch Mechanisms with Adapters Regular Duty Operation Friction clutch mechanism engages with air pressure, spring released when air is exhausted Torque is linear in response to air pressure applied Mounting Clutch mechanisms can be mounted Through/Mid Shaft or End of Shaft Clutch mechanism slides on shaft and is fixed with set screws and a customer supplied key Anti-rotation arm required to prevent rotation of the air housing Clutch mechanisms are designed for horizontal mounting. If vertical mounting is required, consult engineering for options Note: Clutch Mechanism DOES NOT support Adapter Applications Clutch mechanisms are designed for Connect/Disconnect, 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 Clutch mechanisms are bored to suit up to the maximum shown (US & Metric) for easy installation Machined face and bolt circle on adapter facilitate connection to 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.

Mach III clutch mechanisms with adapters are solidly constructed to provide reliable power transmission. 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 clutch mechanism with adapter for use in a new or retrofit application.
