According to relevant projections, calculated at an annual growth rate of 10% - 15%, by 2010, the annual production of automobiles in China will reach over 7.5 to 8 million vehicles. Among them, cars will account for 50%, that is, more than 4 million vehicles, 1.7 million buses, 1.8 million trucks, and about 12 million motorcycles. By 2010, the number of automobiles in use will be approximately 50 million, and the number of motorcycles in use will be about 100 million. By then, China's annual automobile production and ownership will rank among the top in the world. Therefore, the market demand for bearings used for supporting and maintenance of automobile and motorcycle main engines will increase significantly.

The automotive industry is a relatively large comprehensive industry, and its connotations include industries such as metallurgy, casting, material forming, metal processing, automatic control, electronics, spraying, etc. Both the industrial scale and the industries involved are difficult to compare with other industries, and there will be a wide variety of equipment applied in the industry.

There are also many types of bearings installed on automobiles. For example, automotive wheel hub bearings, electromagnetic clutch bearings of automotive air conditioning compressors, center support bearings of automotive drive shafts, tensioner bearings of automotive engines, clutch release bearings of automobiles, and integrated bearings of automotive water pump shafts, etc.
