SHG High Torque Gearhead - Standard Series and New Lightweight Series!

Harmonic Drive® SHG series gearheads are improved, high torque version of the SHF series. All torque ratings and L10 life are all significantly improved compared to the SHF series gearhead of the same size.
  • 30% higher rated torque
  • 30% higher repeated peak torque
  • 30% higher maximum momentary torque
  • 42% longer life (L10 of 10,000 hours)
  • The external dimensions, mass, torsional stiffness, moment stiffness, positional accuracy, repeatability, input moment of inertia, etc. are all the same as SHF series gearheads.
The SHG-2UH series is a compact hollow shaft gearhead which has zero backlash as well as exceptional accuracy and repeatability. The gearhead incorporates a Harmonic Drive® gear component into an integral housing. In addition to the hollow shaft, the gearhead also features a high capacity cross roller bearing and output flange to mount the load without the need for additional support bearings. A New lightweight version is now available which provides the same output torque with a mass averaging 20% lower than the standard series!
