Bearings have a wide range of application. In accordance with the type of host, they can be divided into automotive bearings, electrical bearings, machine tool bearings, home appliances bearings, railway bearings, metallurgical and mining machinery bearings, engineering machinery bearings, petrochemical machinery bearings, wind turbine bearings, agricultural machinery bearings, etc. Among them, the automotive industry is currently a very large market for domestic bearing products, and other such as home appliances bearings, electrical bearings and machine tool bearings are also growing steadily.
More than 70% of the world's bearing market was shared by the top international bearing group companies, such as NSK, SKF, FAG&INA, Timken, TNT, IKO, etc. At the same time, the high-end market of the world's bearing industry is monopolized by the above-mentioned enterprises, while the middle and low-end markets are mainly concentrated in China. At present, the concentration of bearing industry in China is not high, although the degree of automation, product stability and precision have been greatly improved, there are still gaps in some core technology research when compared with the well-known overseas companies.
In the Chinese bearing industry, automobiles and motorcycles are the largest users in the industry. The imported bearing market is targeting hybrid vehicles and electric vehicles, which will create new types of automotive-related products. In this development, the areas involved in micro-bearings will continue to expand, and the precision will also continue to increase. With the continuous development of the Chinese auto industry, there is ample room for development of domestic companies.
Since most domestic bearing companies are lagging behind leading international companies in terms of R&D capital investment, innovation system construction and operation, and personnel training, the bearing accuracy, life, noise and other key factors have not fully met the requirements of high-end machinery. Therefore, in aviation Space, high-speed railway passenger cars, high-grade cars, computers, air conditioners, high-pressure carrying machinery, high-speed machine tools and other fields, many types of bearings need to be imported. With the improvement of technical investment and equipment of Chinese bearing enterprises, bearing indigenous innovation capability will be greatly enhanced, and innovative products are expected to replace imported products and traditional products.
