Why China's high-precision bearings specifically import surge?

In recent years, China's industry, especially the rapid development of the machinery industry. In 2002 the national industry average growth rate of 18.90 percent, 23.39 percent growth machinery industry. Eight categories of major machinery products to create the best pace of development since the founding, where vehicle production 3.477 million, an increase of 38.45% over 2001; the internal combustion engine 284 million kW, an increase 38.33%; metal cutting machine tools 232,000 units, up 19.15 percent. While precision spindle bearings industry is also developing rapidly, but still lagging behind the national industry and machinery industry. Especially focusing host supporting bearings relative lack of supply capacity, resulting in bearing imports soared.

Terms of production volume, China has a spindle bearing producing countries, but also far from bearing an industrial power. At present, varieties and specifications of products bearing a total of about 150,000 in the world, but China can only produce more than 20,000. In China's annual production of various types of bearings in common in the low end bearing account for more than 80%, all kinds of special, precision, high reliability, high-tech, high value-added products bearing account for only about 20%. And China's annual import large quantities of precisely this kind of bearing.

Industry experts point out that the existence of manufacturing standards with the international advanced level of products bearing a considerable gap, mainly in the performance, life and reliability. Such as the level of precision deep groove ball bearings Although quite close to the international advanced level, but there are still "two low and one poor", that is, low level of technology products (less variety, inconsistent quality, poor reliability, technology open to weak ), the low level of product manufacturing (process and equipment behind) and poor international market competitiveness. Such as railway bearings, a foreign country is 800,000 km of life, and we have only 500,000 km. At present, China can provide part of the quasi-high speed railway bearings, but all rely on imports of high-speed railway bearings. In addition there is a second generation, third generation wheel bearings, precision bearings drive computer hardware and software, mute motor bearings, etc., technology development capabilities are quite weak, low product quality and level of development can not meet the needs of the host.

At present, China's annual imports of ball and roller combined bearing as reached about 10 million units, but will also increase year by year, that share a considerable part of the host country support and maintenance markets fell into the others mouth. A piece of "cheese" Although tempting, but we lack the strength to share. To change this situation, industry experts believe that companies must change the current situation alone, together, focus on the integration of industry resources, technical resources, and enhance the overall strength. While continuing to strengthen the joint venture with the world's leading companies, the introduction of technology to improve the level of technology.
