Bearing industry "internal injury" troubled development

China's bearing industry's sales revenue and profit growth in 2010 exceeded 30%, and the increase in profits was higher than the increase in sales revenue. While the bearing industry is developing rapidly, it has also made outstanding contributions to the autonomy of major technological equipment in key areas of China. However, Wang Quanqing, secretary-general of China Bearing Industry Association, told the author that the speed of China's high-end bearings is still not keeping up with the development speed of the mainframe.

The author understands that China still has a large gap in the fields of high-speed rail bearings and wind turbine main shaft bearings and speed increase bearings. Among them, the bearings used in EMUs with a speed of more than 160 km are currently imported exclusively from international giants such as Sweden's 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 a good production and operation, the economic benefits have increased substantially, and exports have rebounded sharply. Imports are still showing momentum.

It is worth mentioning that the China Bearing Industry Association organized a joint research on high-speed rail bearings and large aircraft bearings in 2010, and has achieved initial results. Bearing industry insiders are optimistic that, according to the current research and development speed, if all goes well, in the next two or three years, China-made high-speed rail bearings will be able to truly achieve matching.

Revenue exceeded 100 billion yuan mark
Although the final statistics have not yet been released, the previous data shows that the bearing industry's main business income in 2010 will exceed 100 billion yuan, 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 bearings increased significantly in 2010. It is estimated that the annual bearing output will reach 15 billion sets, an increase of 36.36%. It is estimated that the total profit can be 6.5 billion yuan, an increase of 38.3% over the previous year.

In 2010, the export of bearings will reach 4.15 billion sets, a year-on-year increase, which will reach 53.65%, an increase of 28.9% over 2008; the foreign exchange earned by exports will reach 3.32 billion US dollars, an increase of 63.6% year-on-year, an increase of 11.4% over 2008.

Wang Quanqing analyzed that the sharp increase in exports was mainly due to the development of China's bearing industry in recent years, the technical quality level of micro-small bearing products has been close to the international level, and has occupied a stable market in the global micro-small bearing market.

In 2010, the number of imported bearings will reach 1.8 billion sets, a year-on-year increase of 30%, an increase of 13.7% over 2008. Imports of foreign exchange will reach 3.8 billion US dollars, an increase of 34.38% over the same period of last year, an increase of 41.8% over 2008. The import and export deficit may reach $480 million.

"Internal injury" plagued industry development
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), high-end bearing imports have grown rapidly. At present, all high-speed rail bearings are imported, and some high-speed precision machine tool bearings still need to be imported. In the long run, it will have an adverse impact on the growth of China's strategic emerging industries.

The development speed of some high-end bearings can't keep up with the development speed of the mainframe. First, due to the unstable performance of raw materials, the life and reliability of bearings are unstable, and it is difficult to enter the mainframe market. Second, due to the rapid development of high-end equipment, modern experimental methods such as bearing bench tests for various high-end equipment have not been used. This has led to slower development of bearing development. As a high-speed train bearing component for high-speed rail basic components, international giants such as Sweden's SKF, Germany's FAG, and Japan's NTN are firmly occupying the Chinese market.

In addition, due to the weak scientific research foundation and weak funds, most SMEs have low levels of automation and slow pace of product structure adjustment, resulting in generally low value-added products, which has affected the development speed of SMEs.

Progress in new product development
In 2010, the dominant enterprises in the national bearing industry developed 528 kinds of supporting bearings of 106 major technical equipments in 13 key areas, with an annual sales income of 9.2 billion yuan, and the products reached the level of similar foreign products.

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

Among them, all supporting bearings for aerospace, aviation and defense equipment represented by "God Five", "Shenzhou VI", "Shen Qi", "嫦娥一号", "嫦娥2" and the large thrust rocket and "歼十" Based on domestic, it has completely independent intellectual property rights.

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

The author understands that among the 106 major technical equipment supporting bearings mentioned above, including the eddy and pitch bearings of wind turbines reaching the international advanced level, the secondary pump bearings of nuclear power plants, the quasi-high-speed railway passenger car bearings, and the speed-increasing heavy-duty railways. Truck bearings, high-power locomotive bearings, cement vertical mill bearings, new generation CT machine bearings, third-generation car wheel bearing units, long-life automotive water pump shaft bearings, ultra-precision Senjimir mill bearings, continuous casting production line segment bearings And so on, and they have all achieved industrialization.

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