The "12th Five-year Plan for Development of Mechanical Fundamental Parts, Basic Manufacturing Processes and Fundamental Materials Industry" will explicitly focus on the development of the "12th Five-year Plan" for high-speed, precision and heavy-duty bearings with strong driving force and large radiation effects Industry, in order to improve performance, reliability and longevity as the main direction, and strive to reach or approach the international advanced level. "Planning" also pointed out that with policy support, by 2015, the bearing industry sales will reach 222 billion yuan, the industry average annual growth rate will be between 12% -15%, of which high-speed, precision, heavy and other high-end Bearing growth will be faster.
Bearing is an important and crucial basic component in the equipment manufacturing industry, which directly determines the performance, quality and reliability of major equipment and mainframe products and is praised as the "heart" component of equipment manufacturing. After years of development, China's bearing industry has formed a considerable scale, the national bearing industry in 2010 the output value of about 130 billion yuan, ranking third in the world. Although China's bearing industry has a very large scale of development, but most are concentrated in the low-end, and in the field of high-end bearings, China still has a considerable gap compared with developed countries. Wang Quanqing, secretary-general of China Bearing Industry Association, also made it clear that the development speed of high-end bearings in China can not keep up with the development speed of the host computer. For example, our country has mastered the technology of high-speed EMU with independent intellectual property rights, but the bearings that come with it are basically dependent on imports. At present, most of the high-speed bearings produced by domestic bearing enterprises can only meet the demands of 150 km -180 km of trains. However, the high-speed railway bearings of European and American countries can meet the demand of trains of 350 km / h and 400 km / h. Therefore, at present, High-speed railway bearings basically rely on expensive imports.
Based on the fact that China's high-end bearings are outdated, "planning" is clear, giving full play to the guiding role of industrial policies, raising the industry's access threshold and curbing low-level redundant construction; giving financial and tax supportive policies to "three basic" industries including the bearing industry, The implementation of key components, raw materials import duty-free policy; study and formulate to encourage users to adopt "Sanji" new products and new technology policies. With the policy support increased, I believe that the spring of our country's bearing industry will usher in the development, will speed up the localization process of high-end bearings, and provide a solid foundation for the complete localization of major equipment manufacturing in China.
