Bearing industry trends
"Machine Components, basic manufacturing processes and basic materials industry," second five "development plan" clearly will drive strong radiation effect large high-speed, precision, heavy duty bearings and other machine parts as a "second five" development focus industry, in order to improve performance, reliability and longevity as the main direction, and strive to reach or approach international advanced level. "Planning" also pointed out that, in terms of policy support, 2015, bearing industry sales will reach 222 billion yuan, an average annual growth rate of the industry will be between 12% -15%, of which high-speed, precision, heavy-duty, high-end Bearing the growth rate will be faster. Crossed roller bearings
taper roller bearing is an important equipment manufacturing industry, the key infrastructure components, cross-tapered roller bearing directly determines the major equipment and host product performance, quality and reliability, as the equipment manufacturing "heart" of parts. After years of development, China's bearing industry has formed a considerable scale, national bearing industry in 2010 output value of about 130 billion yuan, ranking third in the world. Despite the scale of China's bearing industry has been very large, but most are concentrated in the low end, while at the high end bearing manufacturing, China and developed countries, there is still a considerable gap. Thin section crossed roller bearing China Bearing Industry Association Secretary-General Wang Quanqing has made it clear that China still can not keep up the pace of development of high-end bearings host of development. For example, China has mastered with independent intellectual property rights of high-speed EMU technology, but also ancillary bearing basic dependence on imports. Currently, the domestic production of high-speed bearings bearing mostly only meet 150 km -180 km of the train, while the United States and Europe to meet the high-speed rail bearing speed of 350 km -400 km train needs, so that the current domestic more than 200 kilometers per hour EMU supporting The basic dependence on expensive high-speed rail bearings imported.
Based on the facts behind our high-end bearings, "plan" clearly will give full play to the guiding role of industrial policy, improve industry access threshold to curb redundant construction; thrust cylindrical roller bearings, including bearings industry, including giving "three bases" Industry fiscal policy to support the implementation of key components and raw materials imported duty-free policy; study and formulate encourage users to adopt the "three bases" of new products and new technology policy. With policy support efforts to increase, I believe the development of China's bearing industry will usher in the spring, will accelerate the localization process of high-end bearings, as China's major equipment manufacturing complete localization to provide a solid foundation
