For applications that require a high torque, Nanotec offers new planetary gearboxes in two sizes and many reductions: the GP42 gearbox is designed for all motors with NEMA 17-flange, as well as the DF45 external rotor motors from Nanotec. The GP56 gearbox can be combined with all brushless DC and stepper motors in sizes NEMA 23 and 24 (56/60 mm). To increase efficiency and service life when subjected to high axial and radial loads, the GP56 is also available with a reinforced output bearing and planetary gears on needle bearings.

Both gearbox series are offered in one- and two-stage versions with a rated torque between 1.8 and 23.5 Nm. Their maximum gear backlash is 0.95°.

By using simulation-based design, the toothing, materials and hardening processes could be significantly improved. The high-torque gearboxes therefore achieve a considerably higher torque than gearboxes of comparable design. In addition, their modular structure enables fast and easy adaptation to individual customer requirements.
