With the development of the host industry, users have put forward higher and higher requirements on the accuracy, performance, life and variety of bearing products. They are not satisfied with the requirements of general bearings, but turn to the requirements of products with high accuracy, low noise and long life, such as low noise and silent motor bearings with no abnormal sound less than 28dB(A).

At present, most bearings produced in China are middle and low grade products, and the proportion of middle and high grade products for the market must be gradually increased. According to relevant statistics, the total demand for small and medium-sized ball bearings in the domestic market will reach 820 million sets in 2005, among which the demand for low noise bearings is 150 million sets. According to the relevant information of the State Economic and Trade Commission, it is expected that by 2005, the total amount of the world bearing export will reach 48 billion DOLLARS, and the amount of domestic bearing export will reach about 850 million dollars. In 2001, China exported 1.54 billion sets of bearings, earning 681 million US dollars in foreign exchange. Bearings exported are still mainly ordinary miniature, small and medium sized ball bearings, with low grade. The average unit price is only 0.44 US dollars, which is 1/5-1/6 of the market price of similar bearings in the United States, Europe and other countries. Therefore, to improve the grade of domestic bearing products, today's focus:

The development of high value-added small and medium sealed low noise motor bearing export is the domestic bearing industry urgent matter.
