China Bearing Industry Status – china 12PSB Test Bench – CRI Tester manufacturer
Bearings are an important foundation for all types of machinery and equipment spare parts, its accuracy, performance, service life and reliability of mainframe accuracy, performance, service life and reliability play a decisive role. In mechanical products, bearings are high precision products requires not only mathematics, physics and many other disciplines the theory of integrated support, but also materials science, heat treatment technology, precision machining and measuring techniques, numerical control technology and efficient numerical methods and powerful computer technology, and many other disciplines to serve, it is also a bearing behalf of the state scientific and technological strength products. Bearing in today’s world powers to Europe, America and Japan led, after 100 years of development, in the global bearings market, high-end products occupy an absolute advantage.
The development of modern bearing industry mainly in the founding of New China, after nearly six decades of construction and development, especially in reform and opening up 30 years continuous, rapid and sound development of China’s bearing industry has formed a complete range, with considerable size and a certain the level of independent industrial system. In 2008 the scale more than 1440 industry-wide bearings and auto parts manufacturers to complete main business income of 88 billion yuan, growing 15.79% over 2007; bearing production to complete 10 billion units, compared with 11.11% growth in 2007; a total profit of 4.5 billion to complete compared with 7.14 percent growth in 2007; bearing exports earned 2.97 billion U.S. dollars, increased 38.07% over 2007; export bearings 3.39 billion units, compared with 2.75% growth in 2007; imports of 2.693 billion U.S. dollars with the exchange than the 2007 increase of 24.99%; imported bearings 1.579 billion units, compared with 0.73% decrease in 2007, import and export trade surplus of 276 million U.S. dollars, over two years in advance the completion of the national bearing industry, “Eleventh Five-Year” plan targets.
At present, China’s bearing industry from the industrial economy of scale has been the world’s total third bearings, but the accuracy of product and technical level with the world’s advanced level there is a considerable gap. Following main features:
1, China’s bearing industry, the production concentration is low. Bearings in the world about 400 billion in sales, the world’s eight largest multinational companies accounted for 75% ~ 80%. Germany, the two companies accounted for 90% of the national total, Japan, five of its 90% of the national total, the United States one of its 56% of the national total. In China, ZWZ, etc. 7 bearings with annual sales of more than 1 billion yuan business, industry-wide sales accounted for only 28.3%.
2, China’s bearing industry with low R & D and innovation capability. Since most enterprises in the innovation system construction and operation, R & D and innovation, capital investment, manpower development, etc. are still at a low level, coupled with service-oriented industry, research institutes towards enterprise, the state has no common industrial technology research inputs, thus weakening the industry-oriented research and development functions. Therefore, the whole industry, “two weak two less” prominent, that is weak in basic theoretical research and participate in international standard-setting is weak, less original technology, less patented products.
At present, our design and manufacturing technology is basically analog, has always been the system for decades. Product development capability is low, reflected in: Although the rate of domestic hosts supporting up to 80%, but high-speed railway passenger cars, medium and high grade cars, computers, air conditioners, and other important high rolling mill and maintenance of bearings supporting the host, 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 in the low rate of car CNC machining, 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 of production is still the traditional equipment. Bearing life and reliability essential to the advanced heat treatment technology and equipment, such as controlled atmosphere to protect heating, double refined, low coverage of bainite hardening, etc., and many technical problems research could not breakthrough.
The new steel bearing steel research and development, improving the quality of steel products, lubricating, cooling, cleaning and abrasives and other related technology research and development, still can not meet the level of bearing products and quality improvement requirements. Thus, resulting in low process capability index, consistency is poor, product processing size dispersion degree, the product bearing the inherent quality of instability affecting the accuracy, performance, service life and reliability.
View of the above situation, China has proposed the bearing industry, “Eleventh Five-Year Plan”, China’s bearing industry is going to be market-oriented enterprises and to promote independent innovation capability and design and manufacturing technology upgrading, promoting large group, “little giant” enterprises to build, enhance core competitiveness, increase production concentration, increased from a size-based to quality and efficiency changes.
Some of the products of some enterprises in 2010 reached an internationally competitive level in order to rank among the world’s powers lay the foundation bearing; in 2020 to achieve by the bearing-producing countries into the ranks of the world bearing the goal of power, in order to speed up the revitalization of China’s equipment industry to make contribution. 2020 goal of achieving world bearing power, product-year precision, performance, service life and reliability over the same period the level of similar products from foreign companies, major equipment, auxiliary bearings to achieve domestic production: design and manufacturing technology lines in the same period the level of foreign companies, there is a core group of Technology independence is only property rights; a 3-5 at home with independent intellectual property rights and world-renowned brands, strong international competitiveness, the advantages of the enterprise; industry, production and sales of the total size of largest in the world, there are 2-3 of the home-owned holding enterprises to enter the world Bearing in sales before 10; industry produced more than 80% concentration.
Recently, the Association launched the “Eleventh Five-Year” plan implementation and progress of technology projects, and industry concentration of production surveys, analysis of the views put forward to guide the development of industries and enterprises to adjust thinking; in 2008, the machine in conjunction grant Wafangdian City ” China Bearing Capital “title, Zhejiang” Cixi Bearing Industry Development Strategy Plan “approved by the specialists to promote the region bearing the healthy development of industrial clusters and enterprises become stronger and bigger, catalytic factors of production to the advantage of enterprises are concentrated.
