The development of composite bearing is the important foundation of all kinds of machinery and equipment parts and components, its accuracy, performance, life and reliability of the accuracy, performance, life and reliability of the host plays a decisive role.In mechanical products, the bearings are high precision products, not only need comprehensive support the theory of mathematics, physics, and many other disciplines, but also need to material science, heat treatment technology, precision machining and measuring technology, numerical control technology and effective numerical method and the powerful computer technology in many disciplines, such as services, thus bearing is a product on behalf of the state science and technology strength.In 2008 after the outbreak of the international financial crisis, countries in response to the financial crisis, take the increasing spending on infrastructure and economy development of the active fiscal policy.Benefit from the development of related industries, bearing rapidly expanding production and sales, profits were promoted, speeding up industrial development.According to the national bureau of statistics, in 2011 China bearing manufacturing industry scale (annual sales revenue of 20 million yuan of above) a total of 1416 enterprises, the annual gross value of industrial output achieved 193.211 billion yuan, up 27.59%;Sales income is 191.097 billion yuan, up 30.30%;Profit total 12.523 billion yuan, year-on-year growth of 26.54%.
In recent years, the world famous enterprises have entered China bearing market, and establish production bases, such as Sweden SKF, Germany schaeffler group, the United States timken, Japan NSK, NTN, etc.These companies is not only a global business, and is a global manufacturing, they rely on brand, equipment, technology, capital and the advantage of the scale of production, with the domestic bearing enterprises launched fierce competition.Nowadays, the domestic enterprise engages in the production of general bearing, and high-end bearing manufacturing enterprise is less, technology is not yet mature.Therefore, the domestic enterprises to compete with foreign advanced bearing brands, and even beyond, still need in such aspects as technology experience for a long time to develop.Effect of "twelfth five-year" period, the national macroeconomic policy will continue to appear, the domestic economic growth remains robust, the international market will also be a slow recovery, the economy stabilises picks up momentum gradually increases.The development of the national economy will pull the infrastructure investment, and the metallurgical, power, construction machinery, building materials, energy, industry development, the national top ten industrial revitalization planning, at the same time for the automotive, aerospace, machine tools, wind power and other industries to provide policy support, the development of the industry demand for bearing will also gradually expanding.In addition, the country's emphasis on the equipment manufacturing industry and the localization of bearing, bearing market in China will have a broader space for development.At the same time, along with the development of Chinese bearing industry mainframe, axle housing product structure will change, the rise in the proportion of high-end products in product, sales unit price will be increased, by 2015, our country bearing production is expected to more than 28 billion sets, advocate business wu income is expected to reach 210 billion yuan, to become the world's largest bearing production and sales base.
The increasing competition in bearing manufacturing industry, large bearing manufacturing enterprise mergers and acquisitions between integration and capital operation, excellent domestic bearing manufacturing enterprises more and more emphasis on industry market research, especially for industrial development environment and product the in-depth study of the buyer.Because of this, a large number of excellent domestic brand of bearing manufacturing rapid rise, gradually become the best bearing manufacturing industry.
