Planet Gear HarmonicPlanetary® Speed Reducer HPG Series Gear Head Type

Features

  • Fast delivery (one week max.)
  • Backlash of less than 3 arc min. (Special product: 1 arc min or less, Model HPG-14A or later)
  • High torque capacity
  • High output bearings for load capacity and moment capacity
  • Easy installation of servo motors from other companies
  • High efficiency: 90% or more (85% or more for model Nos. 11 and 14)

The HarmonicPlanetary® HPG series gear head type is a planetary speed reducer for servomotors featuring high accuracy and high stiffness.

Planetary speed reducers with high levels of accuracy and stiffness created by making the most of HarmonicDrive® precision manufacturing technology and expertise in the field of low-speed reduction. Equipped with a unique backlash removal mechanism, it delivers a high level of rotational accuracy.
It was developed as a high-performance, easy-to-handle gear head for servo motors and is the perfect technology for customer-specific needs.
