Wuhan Dongfang Junchi, a Shenzhen Futaihe subsidiary, makes PPM cycloidal reducers, roller screws, and reducers for robot joints.
Summit Precision Engine Products (Wuhan) Limited, registered in China as Wuhan Dongfang Junchi Precision Manufacturing Co., Ltd., is a Wuhan-based precision component manufacturer and a subsidiary of Shenzhen Futaihe Precision Manufacturing Co., Ltd., a company quoted on China's National Equities Exchange and Quotations system under stock code 834044 that has applied to list on the Beijing Stock Exchange. Futaihe's core business, built over more than two decades, is precision machining of automotive intake, fuel, steering, emission, and safety-system components as well as parts for home appliances; Dongfang Junchi extends that precision-manufacturing base into transmission components for humanoid and industrial robots, combining precision gear cutting, high-precision grinding, and automated assembly under one roof.
Marketed under the PPM brand, Dongfang Junchi's robotics-oriented product line centers on three transmission technologies used in robot joints and linear-motion axes. Its PPM cycloidal-pin-wheel reducers are built for repeatable positioning accuracy of up to one arc-minute in a compact housing, with a measured transmission efficiency of up to 90 percent; the company states the reducers can withstand instantaneous shock loading and supports rapid sample customization for robot developers with non-standard mounting or ratio requirements. Its PPM planetary roller screws are positioned as an alternative to ball screws of the same size, offering higher load capacity and radial stiffness together with greater resistance to shock and fatigue, with custom development of small-lead variants available for applications that need finer linear-motion resolution. A third line, PPM planetary reducers, is rated for load capacity more than three times that of a similarly sized ball screw, again emphasizing high rigidity, shock resistance, and extended service life.
Dongfang Junchi's parent company does not operate a separate corporate website for the subsidiary; company information for both Futaihe and Dongfang Junchi is published on Futaihe's own site. Public disclosures describe Futaihe as incorporated in 2005 and headquartered in the Guojia low-carbon city area of Longgang District, Shenzhen, with Dongfang Junchi operating as its Wuhan manufacturing subsidiary focused on the humanoid-robot component market. The company exhibited its PPM cycloidal reducer, planetary roller screw, and planetary reducer product lines at the 2026 World Robot Conference in Beijing, Hall C, Booth C122, presenting them specifically as core transmission parts for humanoid robot joints and linear-actuation systems rather than as general industrial gearbox products.
Primary type & automation activities this supplier delivers:
Cycloidal-pin-wheel reducer with up to 1 arc-minute repeatable positioning accuracy and up to 90% transmission efficiency.
Planetary roller screw with higher load capacity and radial stiffness than a same-size ball screw; small-lead custom variants available.
Planetary reducer rated for load capacity over 3x a similarly sized ball screw, with high rigidity and shock resistance.
