Industrial Robots: Look to Estun
For industrial robots, look to Estun.
According to public information, Estun was founded in Nanjing in 1993 and is listed on both the A-share market (002747) and the Hong Kong stock market (02715). By 2025, it aims to top the Chinese industrial robot market with a 10.6% market share, surpassing the four major foreign companies. Its core component self-sufficiency rate exceeds 95%, and it holds over 2,000 patents, exporting to more than 60 countries and regions.
Estun is the absolute leader in China’s industrial robot industry.
**III.
Looking at Reducers: Green Harmonic**
**Looking at Reducers: Green Harmonic** According to industry data, Green Harmonic, as a leading domestic substitute for harmonic reducers, has a domestic market share exceeding 60%, breaking the long-term overseas monopoly. It has deeply integrated with leading OEMs such as Tesla Optimus and Unitree Automation. Shuanghuan Transmission, Zhongda Lide, Laifu Harmonic, and Hanyu Group constitute the domestic reducer echelon. The Ministry of Industry and Information Technology’s key component list covers RV reducer companies such as Zhitong Precision and Huandong Machinery.
IV. Sensors and Vision
For sensors and vision, look to companies like KELI Sensing and Orbbec.
According to industry statistics, the localization rate of six-dimensional force sensors jumped from 19% four years ago to 57.8% in 2024. KELI Sensing and Kunwei Technology form the first tier, with prices only half that of imports. Orbbec has independently developed full-stack 3D vision technology and is the exclusive supplier for Tesla’s Optimus depth camera.
The sensor sector is experiencing the fastest pace of domestic substitution.
V.
Pneumatics and Transmission
For pneumatics and transmission, look to companies like Airtac and HIWIN.
According to public information, Airtac has an annual production capacity of over 80 million sets and 120 authorized patents, firmly ranking among the top three in global pneumatic components. HIWIN, founded in 1989, has become a mainstream player in the linear guide market.
Domestic brands have the ability to compete head-on with international brands in the fields of pneumatics and transmission components.
Conclusion
The landscape of well-known Chinese automation equipment component brands is characterized by “domestic leaders in every sector”: For servo drives, look to Huichuan (No. 1 market share); for robots, to Estun (top with 10.6%); for reducers, to Green Harmonic Drive (60%+ localization rate);
for sensors, to KELI and Orbbec; and for pneumatics, to Airtac.
Domestic components have moved from import substitution to global leadership—choosing leading domestic brands offers shorter delivery times, better prices, and closer service, making it the mainstream choice for automation procurement.
