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.
Under the background of China's continuous efforts to develop its industrial base, China's bearing industry has entered a new period of high-quality and rapid development. It has realized the development strategy from small to large and from weak to strong, and has formed a relatively complete industrial system with reasonable layout, coexistence of large and small enterprises and complete product categories.
At present, with the country's emphasis on equipment manufacturing industry and the increasingly obvious trend of bearing localization, China's bearing market will usher in a broader space for development.
The bearing casting industry in China develops rapidly, which has a better effect on the stability of bearing steel market.
The current demand for high-end bearing is increased significantly, such as ball screw bearing with precision angular contact ball bearing photovoltaic industry, aerospace bearings, machine tool precision bearings, high speed motorized spindle bearings, turntable bearings, wind power bearing, rolling mill bearings, high-speed bearing, auto bearing, crane pulley bearing, turbocharger bearing, fluid dynamic pressure bearing, etc.
Robots no longer simply replace manual operations, but will change the way of human production, help various industries to improve production efficiency and product quality, to achieve energy saving and efficiency of modern production and management.
At present, China has successively introduced relevant policies to support the development of high-end equipment manufacturing industry.
In the 12th five-year plan, high-end manufacturing, namely "robot + intelligent manufacturing", is listed as a strategic emerging industry.
Some professional organizations have exaggerated forecast, the industrial robot industry scale is expected to exceed one trillion yuan, the industry prospect of intelligent manufacturing and intelligent equipment is optimistic.
Luo baihui, general secretary of the international association of mold and metal plastic industry suppliers, believes that the robot industry will be a large emerging high-tech industry after the automobile and computer industry.
During the 12th five-year plan period, the demand for industrial robots in China will increase by 15-20% annually.
After more than 50 years of construction and development, China's bearing industry has realized the development strategy from small to large, from weak to strong, and formed a relatively complete industrial system with basically reasonable production layout, coexistence of large and small enterprises, and relatively complete product categories.
And has the bigger production capacity and the stronger technical strength.
At present, China's robot special bearing industry has had a certain scale of production, of which there are dozens of domestic robot joint arm special thin-wall bearing enterprises, employing tens of thousands of people.
In 2011, China's bearing manufacturing industry achieved an annual industrial output of 193.21 billion yuan, up 27.59% year-on-year.
Sales revenue was 19.1097 billion yuan, up 30.30% year-on-year.
Profit totaled 12.523 billion yuan, up 26.54 percent year-on-year.
At present, precision bearing and other basic machinery casting industry has become the national "twelfth five-year" period of key development of the industry, and strive to make it reach or close to the international advanced level.
China's bearing production is expected to exceed 22 billion sets, the total sales volume is constantly improving, becoming the world's largest bearing production and sales base will no longer be out of reach.
