HPG Helical Series

The HPG-R Helical Harmonic Planetary^® gearhead delivers High-Torque and High-Accuracy in a compact package. The Helical gear design combines quiet operation with higher torque when compared to the standard HPG Series. The gearhead incorporates continuous backlash compensation that ensures low backlash throughout the life of the gear. A large Cross Roller bearing serves as the output flange and can directly support large loads with high moment stiffness. HPG planetary gears are available with a flange output, smooth output shaft or a shaft with a key and tapped center hole.

Helical Gearing
