Morse Taper Input Mechanical Friction Torque Coupling


Prevent Overtightening

  • Coupling transmits torque continuously but torque output does not exceed the slip torque setting.
  • No reset is required after coupling slips.
  • Slip torque can be set by Mach III, or can be set and adjusted by the user.
  •  Click here for an illustration detailing how a mechanical friction torque limiter works.
Mounting
  • Torque limiter connects to #3 Morse taper socket
  • Output couplings available for a variety of connections; shafts, nuts, and components
  • Optional torque adjustment arbor available upon request
Applications
  • Opening and closing gate valves, butterfly valves, ball valves, plug valves, mud valves, etc. using a drill with a #3 morse taper socket. 
  • Water treatment and water distribution systems
  • Maximum RPM varies by model. Please consult the detail sheets (below). Consult engineering if the intended application exceeds the listed maximum RPM
  • Not recommended in continuous slip or tension control applications.
