Hangzhou Liangzhi Joint Technology Co. Ltd. 杭州良质关节科技有限公司
"Professional drive-integration solution provider"
Chinese maker of integrated harmonic and planetary joint modules and harmonic reducers for humanoid, quadruped and collaborative robots.
Hangzhou Liangzhi Joint Technology Co., Ltd. is a Chinese manufacturer specializing in the R&D, production and sale of robotic joint modules and harmonic reducers. Founded in 2024 by a team with more than 20 years of reducer factory operation and management experience, the company operates R&D centers in Hangzhou and Shenzhen and production bases in Pinghu (Jiaxing, Zhejiang) and Dalingshan (Dongguan, Guangdong).
Its core product lines are integrated harmonic joint modules, integrated planetary (quasi-direct-drive) joint modules, and harmonic reducers. The integrated joint modules combine motor, driver, encoder and brake in a flat, lightweight package with an inner-rotor structure that supports hollow through-bore wiring; planetary quasi-direct-drive modules are offered from 9 N·m up to 300 N·m of rated torque. Harmonic modules use a dual steel-wheel design with cross-roller bearings to reduce flexspline stress, achieving positioning accuracy up to roughly 20 arcseconds and a pin-type brake that locks mechanically in under 10 ms on power loss. As a pioneer in high-precision planetary reducers (cited accuracy down to 1 arcmin), Liangzhi holds more than 30 national patents and benchmarks its products against European, Japanese and Taiwanese suppliers. The company targets humanoid robots, robotic dogs, wheel-legged robots, collaborative robots, robotic arms, exoskeletons and high-end CNC equipment, offering customized solutions with a quoted 5-7 day delivery cycle and exporting to North America, Southeast Asia and Europe.
