HMHG-V Unit (Hollow & Long Shaft) Series Harmonic Gearing

HMHG-V Series with hat-combination standard structure. The input shaft can connect with the motor directly. The cable of power drive gearbox can go through the low-speed hollow shaft Encoder can be installed on both input and output shafts Especially for Cobot and Joint modular

Features of HMHG-V Unit (Hollow & Long Shaft) Series Strain Wave Gearing


  • The cable can go through the hollow shaft, safer and more reliable

  • Doubled torque/volume ratio, as well as modular design, make it more compact with motor

  • No Backlash

  • Excellent positioning accuracy and rotation accuracy

  • Run out is smaller for install position of motor and encoder

  • 30%higher torque capacity than the HMHS series

  • 43%longer lifetime than the HMHS series


Competitive quality with the above advantages of unit (hollow shaft) strain wave gearing, inquiry Hansmotion to buy harmonic drive
