Bearing is a pivotal component in contemporary mechanical equipment, its main function is to support the rotating shaft or other moving bodies, guide the rotating or moving motion and bear the load transmitted by the shaft or the parts on the shaft. Its performance, precision and reliability play a decisive role in the normal operation of the main body of use.

Bearing products are used in a wide range of applications. According to the type of host matching, it can be divided into automobile bearings, electrical bearings, machine tool bearings, home appliance bearings, railway bearings, metallurgical and mining machinery bearings, engineering machinery bearings, petrochemical machinery bearings, wind power bearings, agricultural machinery bearings and so on. Among them, the automobile industry is currently a large application market for domestic bearing products, accounting for about 30% of the demand quantity; Demand for other products such as home appliance bearings, electrical bearings and machine tool bearings is also growing steadily.

Because most of China's bearing enterprises lag behind the international leading enterprises in terms of R&D investment, innovation system construction and operation, personnel training, etc., the accuracy, life, noise and other related factors of bearings have not fully met the requirements of high-end machinery, therefore, in aerospace, high-speed railway passenger cars, high-end cars, computers, air conditioners, high-voltage bearing machinery, high-speed machine tools and other equipment, many bearings need to rely on imports.

With the support of national policies, with the rapid development of China's equipment manufacturing industry, it is expected that enterprises in the sliding bearing industry will focus on improving the accuracy, performance, life and reliability of bearing products in the future. With the improvement of technology investment and equipment of bearing enterprises, the ability of independent innovation of bearings will be greatly strengthened, and innovative products are expected to replace imported products and replace traditional products.
