Leaderdrive

China's leading harmonic-reducer maker, listed on the STAR Market and now planning a Hong Kong listing.

Suzhou Leaderdrive Transmission Technology Co., Ltd. was founded in 2011; its chairman, Yuyu Zuo, began developing harmonic reducers independently in 2003, and he controls the company together with his younger brother, Jing Zuo. It broke Japan's Harmonic Drive Systems' long-standing monopoly on harmonic reducers, and listed on the STAR Market in August 2020 (688017), often called China's “first harmonic-reducer stock.” A harmonic reducer is compact and has very little backlash, making it a standard component in the arm joints of collaborative robots and humanoid robots, which has made Leaderdrive a sought-after supplier in the humanoid supply chain. In 2025 it reported RMB 571 million in revenue and RMB 124 million in net profit attributable to shareholders, with a domestic market share of about 27.5%. On August 26, 2026, its board approved a plan to issue H-shares and list on the Hong Kong Stock Exchange main board.

ExampleThe forearm and wrist joints of an industrial robot commonly use a harmonic reducer to convert a motor's high rotation speed into high torque.
