Air Engaged Clutch Mechanisms With Couplings

Friction clutch coupling engages with air pressure, spring released when air is exhausted
Torque is linear in response to air pressure applied.

Set screws and customer supplied key connect the clutch mechanism to one shaft and the coupling hub to a second, fully supported shaft.
Shafts must be accurately aligned to prevent premature failure.
Anti-rotation arm required to prevent rotation of the air housing.
Clutch couplings are designed for horizontal mounting. If vertical mounting is required, consult engineering for options.
Note: Clutch coupling mechanism DOES NOT support coupling half.

Clutch couplings connect/disconnect 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.

Both clutch mechanism and coupling half bored to suit up to the maximum shown (US & Metric) to accept differing shaft sizes.
Low coefficient friction lining versions are available for applications requiring slip or a narrower torque range. Contact engineering for details.

All Mach III products can be customized to meet the needs of your application.
