Inline Planetary Gearboxes

vr-seriesVR Series variants

NIDEC-SHIMPO expanded from its early roots in mechanical powertrains into higher precision gearing as the motion control market and servo motor technology started to rapidly evolve. Our initial planetary gearbox series were developed to specifically serve the needs of our major robotics customers in Japan and other areas of southeast Asia. During this product expansion, NIDEC-SHIMPO was able to leverage our production engineering expertise and high volume manufacturing capabilities to become the dominant precision planetary gearbox supplier within the robotics segment and throughout the Asia-Pacific.

NIDEC-SHIMPO followed this early development with the introduction of a high-precision planetary series variety that was more suited to compete throughout the global marketplace. The base design platform for each of these series incorporated a modularity of subassemblies and standardization of components that facilitated high volume, efficient production.

With our inline planetary portfolio, our customers have access to a wide variety of frames sizes, ratios, and many configurations are unmatched across the industry. For performance, quality and overall value, look no further than NIDEC-SHIMPO.
