Applications
  • For tension control applications requiring the clutch to drive a pilot mounted pulley, sprocket, or coupling when engaged
  • Cooling sleeve rotates with the shaft at the speed of the drive input
  • Shaft input clutches can also be used as brakes by fixing the pilot to the machine frame or other stationary surface
  • If clutch will drive the shaft when engaged see the SensiFlex® Pilot Input (PI) model
  • Maximum RPM varies by model. Please consult the detail sheets (below). Consult engineering if the intended application exceeds the listed maximum RPM.
