NEMA Frame Torque Limiters C-Face Mount


  • 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

  • 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


  • Momentary overload protection
  • Torque limiters are not recommended in continuous slip or tension control applications. A SensiFlex® clutch or brake should be used instead.
