I. Two Giants Rival the Standard FA Sector
The standard FA sector is dominated by two giants.
According to industry data, in 2023, MISUMI and Yihda’s domestic sales revenue was approximately RMB 2.98 billion and RMB 2.88 billion respectively, with market shares of approximately 19% and 18%. In 2025, Yihda’s revenue is expected to reach approximately RMB 2.9 billion, ranking first in the slider segment with a 28.4% share.
JLCPCB’s FA sector, leveraging synergy within the electronic supply chain, is projected to increase its market share from 3.8% to 8%-10% in 2025. Beyond the top three, the revenue of other players is less than RMB 100 million.
II. Inovance Dominates the Servo System Market
Inovance dominates the servo system market.
According to MIR Industrial Data, in 2025, Inovance Technology ranked first in my country’s general-purpose servo market with a 30.5% share, followed by Siemens with 8.9% and Panasonic with 7.0%, accounting for a combined 46.4%; Hechuan Technology’s overall market share was approximately 3.2%.
Domestic servo replacement is accelerating, driven by Inovance.
III.
Foreign Dominates the Linear Guide Market
Foreign companies dominate the linear guide market, while Taiwanese companies are rising.
According to industry analysis, Japan’s THK is the preferred choice for ultra-precision high-end equipment, Switzerland’s Schneider is suitable for five-axis and semiconductor ultra-high precision applications, Germany’s Rexroth focuses on gantry milling machines and large stamping, Japan’s NSK is widely used in optical inspection and automotive production lines, and Taiwan’s HIWIN has become a mainstream supplier due to its cost-effectiveness.
Domestic brands (Nanjing Craft, Lishui Dinghan, etc.) are rapidly catching up in the mid-range market.
IV. Airtac Leads the Pneumatics Market
Airtac leads the domestic pneumatic components market.
According to public information, Airtac International Group’s largest production base was established in 2001, with over 5,000 employees, an annual production capacity of over 80 million sets, and 120 authorized patents. It is a national high-tech enterprise and a member of the National Hydraulic and Pneumatic Standardization Technical Committee. In the global pneumatic actuator market, SMC leads with a 14.1% share, and the top five manufacturers account for 50% of the market.
V.
Clear Tiered Market for Reducers
The reducer and motion control markets are clearly tiered. According to industry research, HDSI accounts for approximately 28.6% of the global demand for harmonic reducers;
Guomao Co., Ltd., a leading domestic planetary reducer manufacturer, has orders on hand worth 13.2 billion yuan, while Qinchuan Machine Tool, a long-established state-owned enterprise in RV reducers, has orders on hand worth 17.5 billion yuan; in the frequency converter market, Yaskawa Electric, Rockwell Automation, Fuji Electric, and Inovance Technology rank among the top eight globally.
Reducers and frequency converters are the main battleground for domestic substitution of core robot components.
Conclusion
The ranking of automation equipment component manufacturers is essentially a breakdown by sector: For standard FA parts, look to Yiheda and MISUMI; for servo drives, Huichuan dominates; for linear guides, look to THK and HIWIN; for pneumatics, look to Airtac and SMC;
for reducers, look to Guomao and Qinchuan—the list provides a framework, but the choice still comes down to operating conditions, delivery time, and cost.
There is no absolute “number one,” only the “number one” best suited to your production line.
