High-torque planetary gearboxes

The planetary gearboxes of the GP series are offered in one-, two- and three-stage versions as well as with mounting flanges for all compatible motor series from Nanotec. Through the simulation-based toothing design, they achieve a significantly higher torque than economy planetary gearboxes. Thanks to their modular concept and optimal dimensioning, they are quick and easy to adapt to individual customer requirements.

Combinations with brushless DC motors and combinations with stepper motors possible
Rated torque of 1.8 - 47.85 Nm
Max. gear backlash of 1°
High efficiency
Several reductions

1 Motor flange for all suitable Nanotec motors | 2 Planets and sun- and ring gears made from hardened steel | 3 Output shaft with two ball bearings | 4 Individual shafts possible in series
