In recent years, the rapid development of China's manufacturing industry and the scale effect of the bearing industry chain cluster have laid a solid foundation for the micro bearing industry. With this advantage, China has become the world's largest demand country for micro bearings. With the continuous support of national industrial policies and the strong demand in downstream markets, the scale of China's micro bearing market has rapidly increased. In 2024, the market size of China's micro bearing industry is 12.78 billion yuan, a year-on-year increase of 2.24%.

1、 Industry Overview

Miniature bearings refer to various types of bearings with an outer diameter less than 9mm in the metric series and less than 9.525mm in the imperial series. They are precision mechanical components whose primary function is to support rotating mechanical parts, reduce friction during movement, and ensure rotational accuracy. They are widely used in micro-electromechanical systems (MEMS), small electronic devices, and precision instruments. Based on the friction properties of the moving element, miniature bearings are mainly divided into two categories: sliding miniature bearings and sliding miniature bearings.

2、 Industry Chain

The upstream segment of the miniature bearing industry chain primarily includes raw materials such as bearing steel, nonferrous metals, stainless steel, specialty alloys, modified plastics, and industrial ceramics, as well as production equipment such as multi-axis CNC machine tools, controlled atmosphere hardening equipment, ultra-precision grinding equipment, profilometers, and roundness gauges. The midstream segment encompasses miniature bearing production and manufacturing. The downstream segment primarily utilizes applications in the automotive, home appliance, consumer electronics, medical device, and industrial robotics sectors.

3、 Market size

With the rapid growth of emerging consumer electronics markets, such as smartphones and tablets, and the booming development of industries such as industrial equipment, home appliances, consumer electronics, instrumentation, medical devices, and automobile manufacturing, the overall scale of the micro-bearing industry is showing a rapid growth trend. In terms of technological development, the micro-bearing industry is iterating towards miniaturization, high speed, and long life. This trend is closely related to technological upgrades in downstream industries and the expansion of emerging application scenarios. For example, high-end application areas such as motors for new energy vehicles and artificial hearts for medical devices place higher demands on the precision and performance of micro-bearings. This not only drives the continuous advancement of micro-bearing technology, but also prompts companies to increase their R&D investment to meet market demand for high-performance, high-precision micro-bearings.

In recent years, the rapid development of China's manufacturing industry and the economies of scale of the bearing industry chain have laid a solid foundation for the micro-bearing industry. Leveraging this advantage, China has become the world's largest consumer of micro-bearings. With continued support from national industrial policies and robust demand from downstream markets, the scale of China's micro-bearing market is rapidly expanding. By 2024, the market size of China's micro-bearing industry is expected to reach 12.78 billion yuan, a year-on-year increase of 2.24%.
