Leaderdrive (Green Harmonic)
Leaderdrive, known as Green Harmonic (绿的谐波), is China's leading harmonic reducer manufacturer and a critical supplier to humanoid robot joints.
Company Overview
- Leaderdrive broke the Japanese duopoly in harmonic reducers and became China's first listed harmonic reducer manufacturer.
- Its reducers are used in industrial robots, cobots and increasingly humanoid robot joints.
- As humanoids scale, each unit requires 14-28+ harmonic reducers, making Leaderdrive a prime beneficiary.

Recent Milestones
- 2003 — Founded in Suzhou
- 2019 — Listed on STAR Market, China's first harmonic reducer IPO
- 2025 — 425,200 units shipped; 80–90% of Chinese humanoids using harmonic drives source from Leaderdrive
- Aug 2026 — HK listing (A+H) filed
Actuators & Sensors
- Y-series and lightweight YC-series harmonic reducers.
- Integrated reducer + motor + drive joint modules.
- High precision and repeatability for robot joints.
Supply-Chain Analysis
- Leaderdrive masters the flexspline heat-treatment and machining bottleneck in-house.

- Expanding capacity to meet humanoid demand.
Competitor Comparison
Versus Japanese Harmonic Drive Systems: Leaderdrive wins on price and localization in China. Versus domestic peers (Hengtong, Tongchuan), Leaderdrive leads in scale and qualification.
Global Benchmark
Leaderdrive is the closest Chinese counterpart to Japan's Harmonic Drive, the global benchmark for precision harmonic reducers. Where Harmonic Drive long dominated premium robot joints, Leaderdrive offers comparable accuracy at lower cost and faster domestic supply - a key reason Chinese robot and humanoid makers can cut joint costs. Its 2025 revenue of RMB 571M still leaves it far smaller than Harmonic Drive Systems (JPY 60bn+ scale), so the catch-up story plus the humanoid hand/wrist opportunity is the core narrative; an A+H Hong Kong listing was filed in August 2026 to fund expansion.
