According to relevant estimates, with an annual growth rate of 10%-15%, the annual production of automobiles in China will reach 7.5 million to 8 million by 2010, of which cars will account for 50%, that is, more than 4 million, and 1.7 million passenger cars. There are 1.8 million trucks and 12 million motorcycles. By 2010, the number of automobiles will be about 50 million, and the number of motorcycles will be about 100 million. By then, the annual output and ownership of automobiles in China will be among the highest in the world. Therefore, there will be a significant increase in the market demand for automotive and motorcycle host equipment and maintenance bearings.

The automobile industry belongs to a relatively large integrated industry. Its connotations include: metallurgy, casting, material forming, metal processing, automation control, electronics, spraying, etc. The scale of the industry and the industries involved are all very difficult for other industries. The equipment applied to it will also be very diverse.

There are many types of bearings installed on automobiles, such as automotive wheel bearings, electromagnetic clutch bearings for automotive air-conditioning compressors, center support bearings for automotive transmission shafts, automotive engine tensioner bearings, automotive clutch release bearings, and automotive water pump shaft bearings.
