Bearing companies improve bearing reliability and accuracy
Bearings are a very important component of contemporary machinery. Their main function is to support rotating shafts or other moving bodies, to guide the movement of movement or movement and to withstand the loads transmitted by the shaft or parts on the shaft. Its performance, accuracy and reliability play a decisive role in the normal operation of the user.
Bearing products are used in a wide range of applications. According to the type of host matching, it can be divided into automotive bearings, electrical bearings, machine tool bearings, home appliance bearings, railway bearings, metallurgical mining machinery bearings, engineering machinery bearings, petrochemical machinery bearings, wind power bearings, agricultural machinery bearings and so on. Among them, the automotive industry is currently a large application market for domestic bearing products, accounting for about 30% of the required volume; other demand for home appliance bearings, electrical bearings and machine tool bearings is also growing steadily.
Since most of China's bearing enterprises lag behind international leading companies in R&D capital investment, innovation system construction and personnel training, the bearing precision, life, noise and other factors have not fully met the requirements of high-end machinery. Therefore, in aviation On aerospace, high-speed railway passenger cars, high-end cars, computers, air conditioners, high-voltage load-bearing machinery, high-speed machine tools and other equipment, many bearings need to rely heavily on imports.
With the support of national policies, with the rapid development of China's equipment manufacturing industry, it is expected that the future sliding bearing industry enterprises will focus on improving the precision, performance, life and reliability of bearing products. With the technical investment and equipment improvement of bearing enterprises, the independent innovation capability of bearings will be greatly enhanced, and innovative products are expected to replace imported products and replace traditional products.
