HPG-U1

The HPG Harmonic Planetary® gearhead has the same high performance specifications as our standard HPG series but with an input shaft for shaft couplings or for use with motor offset with a belt drive. Same as the HPG, this gearhead incorporates continuous backlash compensation that ensures low backlash throughout the life of the gear. The large Cross Roller bearing serves as the output flange and can 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.
