[Chinese excavator network] China's bearing industry in 2010 sales revenue and profit growth are over 30%, and the profit increase is higher than the increase in sales revenue. The rapid development of the bearing industry has also made outstanding contributions to the autonomy of major technology and equipment in key areas of China. However, the Secretary-General of the China Bearing Industry Association, Wang Quanqing, admitted to the author that the development speed of high-end bearings in China is still not keeping pace with the development speed of the host.

The author has learned that China still has a big gap in the fields of high-speed iron bearings and wind turbine spindle bearings and gearbox bearings. Among them, the bearings used by EMUs with speeds over 160 kilometers per hour are currently completely imported from Swedish giants such as SKF.

The author recently learned from the China Bearing Industry Association that China's bearing industry achieved rapid development in 2010. By the end of 2010, the bearing industry had achieved good production and economic efficiency, and exports had risen sharply. Imports were still rising.

It is worth mentioning that the China Bearing Industry Association organized a joint research project on high-speed rail bearings and large aircraft bearings in 2010, and has achieved initial results. Bearing industry experts are optimistic that according to the speed of current research and development, if all goes well, in the next two to three years, China's domestic high-speed rail bearings will be able to truly support them.

Revenues exceeded the one-hundred-tillion mark Although the final statistics have not yet been released, the preliminary data show that the income from the main business of the bearing industry in 2010 will exceed the one-hundred-twenty billion yuan mark, reaching 120 billion yuan, and the growth rate will reach 30%. Driven by the automobile, agricultural machinery, and home appliance industries, the demand for small-sized bearings increased significantly in 2010. It is estimated that the annual bearing output will reach 15 billion sets, an increase of 36.36% over the same period of last year. It is estimated that the total profit can reach 6.5 billion yuan, an increase of 38.3% over the previous year.

In 2010, bearing exports will reach 4.15 billion sets, which is an increase of 53.65% over the same period last year and an increase of 28.9% from 2008. Exports will reach 3.32 billion U.S. dollars, a year-on-year increase of approximately 63.6%, and an increase of 11.4% over 2008.

Wang Quanqing analyzed that the major growth in exports was mainly due to the development of the bearing industry in China in recent years. The technical level of micro-bearing products is close to the international level, and it has occupied a stable market in the global miniature bearing market.

In 2010, the number of imported bearings will reach 1.8 billion, an increase of 30% year-on-year, and an increase of 13.7% over 2008. The import exchange will reach 3.8 billion U.S. dollars, an increase of 34.38% year-on-year, about 41.8% more than in 2008. The import and export deficit may reach 480 million U.S. dollars.

"Internal injury" hampers the development of the industry However, the problems in the development of the bearing industry cannot be ignored.

With the development of China's strategic emerging industries (such as high-speed railways, large aircraft) and high-end equipment manufacturing (such as some high-speed precision machine tools), imports of high-end bearings have increased rapidly. At present, high-speed rail bearings are all imported, and some high-speed precision machine tool bearings need to be imported. In the long run, it will have an adverse effect on the growth of China’s strategic emerging industries.

Some high-end bearing development speed can not keep up with the development speed of the host. First, due to the unstable performance of raw materials, the bearing life and reliability are unstable, and it is difficult to enter the host market. Second, due to the rapid development of high-end equipment, various types of high-end equipment such as bearing pedestal test and other modern experimental methods have invested too much without As a result, bearing development progressed slowly. As the high-speed train bearing field of high-speed rail base components, the international giants such as Swedish SKF, German FAG, and Japanese NTN are still firmly occupying the Chinese market.

In addition, due to weak scientific research foundation, weak capital, low level of automation, and slow pace of product structure adjustment, SMEs generally have low added value, which affects the development speed of SMEs.

Advances in new product research and development Progress in the national bearing industry in 2010 The company has researched and developed 528 types of supporting bearings for 106 major technical equipments in 13 key areas. The annual new sales revenue is 9.2 billion yuan, and the products have reached the level of similar foreign products.

Wang Quanqing emphasized that the bearing industry contributed to the autonomy of major technological equipment in key areas in China in 2010.

Among them, all supporting bearings for aerospace, aerospace and defense equipment represented by "God 5", "Shenzhou VI", "Shenzhou 7", "Chang'e I" and "Chang'e II", and thrust rockets and "Ji Shi Shi" are represented. Based on the domestic, with full independent intellectual property rights.

In addition, the design and manufacturing technology and physical quality of micro-ball bearings have reached the international advanced level and have strong international competitiveness. Micro-bearing ball bearing grinding, super-finishing and assembly automatic production lines, the industry has increased to more than 3,000.

The author understands that among the above mentioned 106 types of major technical equipment supporting bearings, it includes the yaw and pitch bearing of wind turbines that have reached the international advanced level, the secondary pump bearings of nuclear power plants, the bearings of quasi-high speed railway passenger cars, and the heavy-load railway Truck Bearings, High Power Locomotive Bearings, Cement Vertical Mill Bearings, New Generation CT Bearings, Third Generation Car Wheel Hub Bearing Units, Long Life Automotive Water Pump Shaft Bearings, Super Precision Sendzimir Mill Bearings, Continuous Casting Production Line Segmental Bearings And so on, and all have achieved industrialization.

In addition, one thousand tons of hydraulic crawler crane bearings, high horsepower agricultural equipment bearings, high-speed steam spinning bearings, 10 million tons of coal shaft mining equipment bearings, major CNC machine tool spindles, rotary table bearings, 12,000 meters high reliability Ultra-deep well oil drilling rig bearings, high-speed, high-temperature, long-life chemical fiber equipment bearings, long-life mine shaker bearings and thin-walled robot bearings have also been successfully developed and industrialized.
