Shimpo Planetary Gearboxes

VR Series variants, ABLE® product family

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. These series have been branded as our ABLE® planetary gearbox family of series, which have become the highest performance, highest quality, and most cost effective gearbox in its competitive class.

With our ABLE® planetary series, our customers have access to a wide variety of frames sizes, ratios, and input bore options that are unmatched across the industry. The performance specifications match-up or exceed our competitors' most equivalent series, while offering drop-in dimensions for easy form, fit, and function.
