I. SMC for Pneumatic Components
For pneumatic components, SMC and Festo are the top choices. According to public information, SMC was founded in 1959 and is headquartered in Tokyo, Japan.
It is a leading global pneumatic company, with products covering pneumatic control from robots to medical and semiconductor manufacturing equipment. German company Festo, along with SMC, Bosch Rexroth, and Parker, ranks among the top five global pneumatic actuator manufacturers.
SMC and Festo are the preferred choices for international procurement of pneumatic components.
II.
THK and HIWIN for Linear Motion
For linear motion, THK, HIWIN, and Rexroth are the top choices.
According to industry analysis, THK pioneered linear motion systems globally in 1972, making it the preferred choice for ultra-precision high-end equipment; HIWIN, founded in Taiwan in 1989, has become a mainstream supplier in the market due to its cost-effectiveness;
Rexroth, specializing in gantry milling machines and large-scale stamping applications, offers online selection tools.
These three companies are indispensable for selecting ball screws and linear guides.
**III. Bearings: SKF and NSK**
**Bearings: SKF and NSK**.
According to public information, the SKF Group is a leading global supplier of rolling bearings, seals, mechatronics, and lubrication systems, and will launch new products such as medical CT steel wire raceway ball bearings and hybrid ceramic ball bearings in 2026; NSK has been producing bearings in Japan since 1916, with products covering wind turbines, machine tools, high-speed rail, and linear guides.
The high-end bearing market is still dominated by European, American, and Japanese brands.
**IV. Reducer Duopoly**
**Reducers:** The market is dominated by two major players.
According to industry research, Nabtesco RV reducers from Japan hold approximately 35%-60% of the global market share and are the industry standard for industrial robots; Harmonic Drive, as the inventor of harmonic reducers, holds over 70% of the global market share.
Precision reducers are the main battleground for domestic substitution of core robot components in China.
V. Servo Systems: Siemens and Yaskawa
For servo systems and controllers, Siemens and Yaskawa are the top choices.
Industry analysis shows that Japanese servo brands (Panasonic, Yaskawa, and Mitsubishi) collectively account for approximately 45% of the market share, while European and American brands (Siemens and Bosch) dominate the high-end market; the four major industrial robot manufacturers—FANUC, Yaskawa Electric, ABB, and KUKA—collectively hold over 50% of the global market share.
Siemens and Yaskawa are the preferred suppliers for international servo and control components.
Conclusion
Which international brands are there for automation equipment components? The answer is “one dominant player in each category”: for pneumatics, SMC and Festo; for linear motion, THK, HIWIN, and Rexroth; for bearings, SKF and NSK; for reducers, Nabtesco and Harmonic Drive Systems; for servo drives, Siemens, Yaskawa, and Panasonic;
and for standard parts platforms, MISUMI. International brands win through technological accumulation and global validation.
They are more expensive, but their quality is consistent—using international brands for critical workstations ensures precision, while using domestic alternatives for ordinary workstations controls costs—this is the optimal combination.
