Located in Changzhou, Jiangsu, Jiangsu Runfu Robot Co., Ltd. has devoted 16 years to the R&D and industrialization of planetary roller screws. It is one of the very few companies in the world capable of commercial production of planetary roller screws, and the only one currently implementing full-series volume production. Technology-based and innovation-driven, the company has built an R&D and manufacturing system centered on planetary roller screws, planetary thread roller bearings and system integration, and electric servo transmission devices. It has created a proprietary high-precision, high-stability, high-efficiency advanced manufacturing system for planetary roller screws, pioneering the world's first "nanometer-precision" planetary roller screws, achieving full-process independent control with performance benchmarking international top levels and filling the global gap in planetary roller screw mass production.
