The growth of high-end bearings has entered the fast lane, with emerging demand becoming the core engine.

The high-end machine tool bearing market in China is expanding at an astonishing speed. Data shows that the market size is expected to reach 18.7-21.8 billion yuan by 2025, and will climb to 32.6-38 billion yuan by 2030, with a compound annual growth rate of 11.8%. Behind this growth trend are the continuous efforts of two core driving forces: on the one hand, the process of domestic substitution is accelerating. In the past, over 80% of the domestic high-end bearing market relied on imports, but now with the improvement of local enterprises' technological capabilities, the market share of foreign brands has decreased from 79% in 2018 to below 30% in 2025, and domestic bearings are gradually gaining a foothold in the mid to high end market. On the other hand, the upgrading of intelligent manufacturing has given rise to a strong emerging demand.

In the field of new energy vehicles, the 800V high-voltage platform promotes the penetration rate of ceramic insulated bearings to exceed 30%, with a single unit value of 5000-10000 yuan; The annual growth rate of demand for bearings used in semiconductor equipment is as high as 30%, becoming a new engine driving industry growth.

CNC machine tool spindle bearings account for 40% of the high-end bearing market, with high-speed electric spindle bearings and large heavy-duty bearings growing at an annual rate of 15.2% and 13.6% respectively, reflecting the urgent demand for precision machining equipment in high-end manufacturing industries such as aerospace and precision molds.

Taking industrial mother machines as an example, the spindle bearings and spindle components, as well as the rotary worktable components, are the core functional components of CNC machine tools. Their performance directly determines the machining accuracy, efficiency, load-bearing capacity, and reliability of the machine tool, and is a key indicator to distinguish high-end machine tools from low-end machine tools.

The bearing has a significant impact on machining accuracy, directly affecting machining efficiency, greatly affecting the dynamic response of the machine tool, and also directly affecting the rigidity and stability of the machine tool.

Bearings have an impact on the thermal stability of machine tools, as well as on their lifespan and reliability.

The spindle component is the integrated carrier of the "power core" of the machine tool. The essential difference between high-end machine tools (such as five axis machining centers) and mid to low end machine tools lies in the performance of spindle bearings, spindle components, and rotary workbenches. For example, the gap between domestically produced high-end machine tools and German DMG lies in the difference in spindle bearing life (12000 hours domestically vs. 20000 hours imported) and worktable positioning accuracy (5 arc seconds domestically vs. 2 arc seconds imported).

The market demand for high-end manufacturing is huge, and in fields such as aerospace, semiconductors, and precision molds, the precision of parts is required to reach the micrometer level (such as the cavity accuracy of chip packaging molds ± 0.002mm). For example, the positioning accuracy of the worktable of domestic lithography machines directly affects the chip manufacturing process.

The spindle bearings, spindle components, and rotary worktable components are the "heart" and "joints" of machine tools, and their performance directly defines the machining accuracy, efficiency, reliability, and application boundaries of the machine tool. They are the "cornerstone" of high-end equipment manufacturing.
