NEMA Frame Mechanical Friction Torque Limiter


Overload Protection Between Motor and Gear Box or Other Flanged Components

Operation

Continuously engaged friction torque limiter slips when torque setting is exceeded. Continues to slip until overload ceases.

Applications
  • Momentary overload protection
  • Torque limiters are not recommended in continuous slip or tension control applications. A SensiFlex® tension control 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
  • Enclosed with aluminum, clear anodized aluminum or stainless steel housing
  • Torque setting is factory set at value specified by user
  • Torque adjustment nut can not be manipulated without disassembly of the housing

Additional Information

  • Catalog model NEMA frame torque limiters are not designed for use with a sprocket or pulley on the output shaft and do not support overhung loads. If your application requires this, contact our engineering department to explore options.
  • Mach III friction torque limiters do not disengage upon overload. A means of sensing and stopping the overload condition must be in place or a friction torque limiter will continue to slip, eventually overheating to the point where it is unfit for continued use. See our Torque Limiter Application and Use Guide for more details.
