Air Engaged Clutch Mechanisms With Couplings

Connect Two Supported Shafts with No Angular Misalignment and/or Parallel Offset

Function: Connect, Disconnect
Drive Arrangement: Shaft to Shaft, No Angular Misalignment and/or Parallel Offset

Operation

  • Friction clutch coupling 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 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.

Applications

  • 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.

Design Features

  • 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.
