NEMA Frame Mechanical Friction Torque Limiter


Continuously Engaged, Momentary Overload Protection

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 limiter mounts between a c-face motor and gear reducer
  • NEMA Frame Torque Limiter is not suitable for belt drive (pulley output) applications. Consult engineering
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
  • Enclosed design 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
