In recent years, domestic wind power, high iron,brass bushing automobile, shipbuilding, engineering machinery, etc open huge equipment requirements market, but as the key foundation of accessories bearing but become the soft rib. "Independent production ability touch, high-end dependence on imported, technology KongXinHua questions and be at present our country bearing industry issues that need to be resolved. If these problems are resolved in our country for a long time, many important equipment product research and developmentDU bushing and the production will increase the difficulty, greatly influence the development of relative industries.
Academician of Chinese academy of engineering LuBingHeng think, should be in the industrial development policy, technology development planning etc make key layout, solve the equipment manufacturing industry in high-end bearing development lags behind. China bearing industry association secretary-general WangQuanQing said, "1025"Mould guide plate period, domestic bearing industry will around the key words of independent innovation, research core technology to realize industry upgrading, and strive to replace the imported.
Luoyang precision bearing according to the yue company controller introduces, the equipment manufacturing industry in China in recent years the rapid development, but as a major equipment machinery supporting plasic bushing bearing such core components have become major equipment developing countries the soft spot. "The high iron, for example, although our country already has the independent intellectual propertyplain bearing rights high-speed train technology, but the application of supporting bearing localization is still blank. At present, China's high-speed bearing most only to satisfy a speed of 150-180-km emu,brass bushing and the European and American countries can meet high iron bearing speed of 350-400-km demand. So, the current domestic speed of 160 km above the emu supporting high iron bearing almost all imports. In addition, large wind generator bearing, high-end auto-hub bearing, deep well drilling turntable bearing, offshore drilling platform series bearing energy equipment high-end bearing is the soft rib of the development of the industry.
At present our country import of high-end bearing is mainly from the United States, Japan, Sweden, Germany, Romania and other western countries, the world nearly 80% of bearing is made from these countries of the multinational company production. Their bearings on the reliable steel raw material, exquisite technology and high quality is almost a monopoly of our domestic high-end bearing market. And although China has about 6000 home bearing enterprise, top ten enterprise sales combined bearing accounts for only the industry nearly 40% of the share.
According to not complete count, 2009, our country bearing industry output reached 10 billion sets, the output value has reached 90 billion yuan RMB, the world's third largest. The above 1750 enterprises of scale among them, with annual sales of 3 billion yuan of above only 5 home, but import and export trade deficit of more than 800 million dollars. WangQuanQing said the situation in 2010 is improving, but annual deficit still high reached 5 ~ $600 million between, import bearings in high-end market still monopoly bearing.
Bearing industry in our country there are enterprise, in small scale, the product of a single, industry concentration of poor serious problem; The product structure is unreasonable, the large proportion of low end products, most key of the independent innovation ability is insufficient, insufficient investment in science and technology, research and development, the industry average of r&d investment in the low sales proportion. Precision bearings, high-speed train bearing, civil aviation bearing for foreign companies are bearing monopoly. Luoyang bearing the pleasant company has been committed to the independent innovation, research and development of high precision of precision bearings, has made a major breakthrough, not only complete types, and excellent quality, the price is low, the technology is in the lead, 70% of its products have has the ability to replace imported products, greatly promote the progress of the domestic bearing.
