High-torque planetary gearboxes

High-torque planetary gearboxes

The planetary gearboxes of the GP series are offered in one- and two-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.

GP42: for motors in size NEMA 17 and external rotor motors with flange diameter of 42.8 mm
GP56: for motors in size NEMA 23/24

planetary gearbox manufacturer

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
