Mechanical Friction Torque Limiter – Through Shaft

Continuously Engaged, Momentary Overload Protection

Function: Overload Protection
Drive Arrangement: Shaft to Pilot Mounted Component or Pilot Mounted Component to Shaft

Operation

  • Mechanically adjustable, continuously engaged friction torque limiter slips in the event of an overload.
  • Torque at which limiter will slip is field adjustable through the tightening or loosening of a nut.
  • Adjustment nut is locked in place by set screws when desired torque setting is established.

Mounting

  • Torque limiters can be mounted Through/Mid Shaft or End of Shaft.
  • Torque limiter slides on shaft and is fixed with set screws and a customer supplied key.

Applications

  • Momentary overload protection.
  • Torque limiters are not recommended in continuous slip or tension control applications. A SensiFlex┬« clutch or brake should be used instead.
  • Maximum RPM varies by model. Please consult the detail sheets (below). Consult engineering if the intended application exceeds the listed maximum RPM.

Design Features

  • No reset required after torque limiter slips.
  • Torque limiters are bored to suit up to the maximum shown (US & Metric) for easy installation.
  • Machined pilot for easy mounting of pulley or sprocket.
