Superior performance
The NBPG NB300R Series gearbox is a right angle gear drive and the best solution for all applications requiring high torque with minimum dimensions for fixed industrial equipment and heavy self-propelled machines. This planetary gearhead offers a substantial improvement over traditional gearboxes in terms of size and weight. The modular design combines high performance with low cost due to its compact size, excellent reliability, simple installation, and reduced maintenance. The NB300R Series planetary gearboxes come in a range of sizes to ensure optimum duration and silent running in all sorts of applications.

The NB300R Series is also available in a high power version, linking the performance of NBPG's planetary technology with the high quality and reliability of gearboxes: a solution that is more efficient, quieter, more compact, and offers a better price/performance ratio compared with traditional gear units.
