In recent years, the domestic bearing industry, the rapid expansion of production scale, ranked fourth in the world, bearing nearly 2,000 enterprises, of which sales of more than 500 million companies in more than 900, DU bushing the number of world-first.
China is the axis Cheng Daguo, but not bearing power. On the whole country has entered the ranks of the world axis Cheng Daguo, but the product mix away from the bearing power of China is still a long gap. Industry production concentration is low, high-end products to match the low R & D capabilities of bearings, bearing low level of manufacturing technology industry still exists, the import and export trade deficit expanded.
1, China's bearing industry, the production concentration is low.
Bearing in the world about 300 billion in sales, the world's largest multinational companies accounted for 8,Mould guide plate 75-80. Germany, the two companies accounted for 90 of the national total, the Japanese five of its 90 national total, the United States one of its 56 national total. In China ZWZ other seven bearings with annual sales of more than 10 billion enterprise, industry-wide sales accounted for only 28.3, the top 30 companies in the production concentration has only 43.6.
2, plasic bushing China's bearing industry R & D and innovation abilities.
Since most enterprises in the construction and operation of innovation systems, R & D and innovation, capital investment, human development is still at a low level, coupled with industry-oriented research institutes into enterprise services, the state has no common industrial technology research investment, thus weakening the industry-oriented research and development functions. Therefore, the whole industry, "two weak two less" outstanding, basic research that is weak, weak participation in international standard-setting, less original technology, less patented products. At present, our design and manufacturing technology is basically a simulation, consistent system for decades. Product development capacity, and features: While the matching rate of the host country 80, but the high speed passenger trains, high-end cars, computers, air conditioners, high rolling mill and other important support and maintenance of the host bearing, basically rely on imports.
3, China's bearing industry, the low level of manufacturing technology.
China's bearing industry manufacturing processes and process equipment and technology developed slowly, low rate car CNC, grinding low level of automation, there are only more than 200 automated production lines. Most enterprises, especially the old state-owned enterprises as the main force is still the traditional production equipment. Critical to bearing life and reliability of advanced heat treatment technology and equipment, such as the protection of controlled atmosphere heating, double refined, low coverage of bainite quenching, many technical problems research failed to reach a breakthrough. New steel bearing steel research and development, improving the quality of steel, lubrication, cooling, cleaning and abrasives, and other related technology research and development, still bearing products can not meet the requirements of the level and quality improvement. Resulting in low process capability index, consistency is poor, size dispersion processing, product instability inherent quality of the bearing accuracy, performance, life and reliability.
View of the above conditions, the bearing industry of China made "Eleventh Five-Year Plan", China's bearing industry will be market-oriented enterprises as the mainstay, promote independent innovation and design and manufacturing technology upgrading, promoting large groups, "little giant" enterprises to build, enhance core competitiveness, increase production concentration, growth from a scale change to the quality and efficiency. Some of the products of some enterprises in 2010 reached the level of international competitiveness for power among the ranks of the world bearing basis; 2020, producing countries from the bearing into the ranks of the world bearing the goal of power, in order to accelerate the revitalization of China's equipment manufacturing industry to make contribution. World power by 2020 target bearing, product accuracy, performance, life and reliability over the same period the level of similar products from foreign companies, major equipment, bearings supporting the realization of localization: the design and manufacturing technology to achieve the level of large companies outside of the circle over the same period, a number of core technologies independent intellectual property rights; a 3-5 home with independent intellectual property rights and world-renowned brands, the advantage of strong international competitiveness of enterprises; industry production and sales of the total size of largest in the world, holding a 2-3 domestic enterprises to enter the world bearing sales of the top 10; industry produced more than 80 concentration.
