Composite bearings are an important foundation for all types of machinery and equipment parts, its precision, performance, longevity and reliability of the mainframe precision, performance, longevity and reliability plays a decisive role. Mechanical products, bearings are precision products, requires not only a comprehensive support mathematics, theoretical physics and many other disciplines, but also materials science, heat treatment technology, precision machining and measurement technology, digital technology and efficient numerical methods and powerful computers technology and many other disciplines to serve, so the bearing is a representative of the national scientific and technological strength of the product. After the international financial crisis in 2008, the national response to the financial crisis, has taken to increase infrastructure investment and stimulate economic development in the proactive fiscal policy. Benefit from the development of related industries, bearing production and marketing of rapid expansion, the profit level is improved, significantly accelerate the development of the industry. According to the National Bureau of Statistics, China's bearing manufacturing industry scale in 2011 (with annual sales income of 20 million yuan or more) companies a total of 1416 companies, total industrial output value of 193.211 billion yuan, an increase of 27.59%; sales revenue of 191.097 billion yuan, an increase of 30.30%; total profit of 12.523 billion yuan, an increase of 26.54 percent over the previous year.
In recent years, world-renowned enterprises have entered the Chinese bearing market, and the establishment of production bases, such as the Swedish SKF Group, the German Schaeffler Group, Timken Co., Japan's NSK company, NTN Corporation. These companies not only global business, and global manufacturing, by virtue of their superior brand, equipment, technology, capital and production scale, and domestic bearing companies engaged in a fierce competition. Today, domestic enterprises are mainly engaged in the production of universal bearing, less special and high-end bearings manufacturer, technology is not mature. Therefore, the domestic enterprises in order to compete with foreign advanced products bearing the brand, and even beyond, but also need to go through a long period of time in terms of technology development. "Twelve Five" period, the state will continue to show the effect of macroeconomic policy, domestic economic growth remains strong, international markets will slow recovery, and gradually increase the momentum of economic recovery. Development of the national economy will boost investment in infrastructure construction, thus promoting the development of metallurgy, electric power, construction machinery, building materials, energy and other sectors, while the state has adopted ten industrial revitalization plan, to automotive, aerospace, machine tools, wind power and other industries provide policy support for the development of these industries demand for bearings will be gradually expanded. In addition, national attention and localization trends bearing equipment manufacturing industry has become increasingly evident that China bearing market will usher in a broader space for development. Meanwhile, with the development of the host country bearing industry, bushings product mix will change, its high-end products in the product increased the proportion, the sales price will also increase, expected by 2015, China's bearing production is expected to more than 28 billion sets, the main business income is expected to reach 210 billion yuan, becoming the world's largest bearing production and sales base.
