After the outbreak of the international financial crisis in 2008, China adopted a proactive fiscal policy, increased infrastructure investment, promoted economic development, and responded to the financial crisis. Benefiting from the development of related industries, bearing production and sales have rapidly expanded, profit levels have been improved, and industry development has accelerated significantly. In 2010, China's bearing industry realized sales revenue of 151.969 billion yuan, a year-on-year increase of 39.45%; realized industrial output value of 151.434 billion yuan, a year-on-year increase of 38.04%; profit was 9.812 billion yuan, a year-on-year increase of 69.37%. According to the "China Bearing Manufacturing Demand Forecast and Transformation and Upgrading Report" issued by the Foresight Industrial Research Institute, German Schaeffler Group, American Timken Company, Japanese Sk Company, and ntn Company, in recent years, world-renowned companies have entered Chinese bearings. In the market, production bases such as the Swedish skf group have been established. These companies not only operate globally, but also manufacture globally. Relying on the advantages of brand, equipment, technology, capital and production scale, they have launched fierce competition with domestic bearing companies. At present, domestic enterprises are mainly engaged in the production of general-purpose bearings, while there are few manufacturers of special bearings and high-end bearings, and the technology is not yet mature. Therefore, if domestic enterprises want to compete with or even surpass foreign advanced bearing brands, they also need to experience a long-term development process in terms of technology.

Bearings are an important basic component of the equipment manufacturing industry, which directly determines the performance, quality and reliability of main equipment and host products, and is the "heart" component of the equipment manufacturing industry. After years of development, my country's bearing industry has formed a considerable scale. In 2010, the output value of the national bearing industry was about 130 billion yuan, ranking third in the world. Although the scale of development of my country's bearing industry is large, most of it is concentrated at the low end, but in the field of high-end bearing manufacturing, there is still a big gap compared with developed countries. Rolling bearing is a precision mechanical component that converts the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling elements and cage. The inner ring matches the shaft and rotates with the shaft. The cage makes the rolling elements evenly distributed between the inner ring and the outer ring to prevent the rolling elements from falling off. The rolling elements are guided to rotate and lubricate. The shape, size and number of the rolling elements directly affect the performance and life of the rolling bearing. According to the "2012-2016 China Bearing Industry Survey and Market Prospect Consulting Report" released by China Business Intelligence Network, in the first half of 2012, the national rolling bearing output reached 8.375 billion sets, an increase of 7.21% year-on-year. In June, China produced 1.738 billion sets of rolling bearings, a year-on-year increase of 9.35%
