Since the modern industrial revolution, bearings have become a significant component in mechanical components. China is one of the countries that invented rolling bearings earlier in the world. In China's ancient books, the structure of axle bearings has long been recorded. Bearings are important basic components of all kinds of mechanical equipment. Its accuracy, performance, longevity and reliability play a decisive role in the accuracy, performance, life and reliability of the main engine. In mechanical products, bearings are high-precision products, which not only require comprehensive support of many disciplines such as mathematics and physics, but also require materials science, heat treatment technology, precision machining and measurement technology, numerical control technology and effective numerical methods and powerful computers. Technology and many other disciplines serve it, so the bearing is a product that represents the country's scientific and technological strength.
After the founding of the People's Republic of China, under the strong impetus of reform and opening up, China's bearing industry has entered a new period of high quality and rapid development, and has achieved a development strategy from small to large, from weak to strong, forming a rational and large layout. A relatively complete industrial system in which SMEs coexist and products are relatively complete. At present, with the country's emphasis on equipment manufacturing and the trend of bearing localization, China's bearing market will usher in a broader development space.
China's bearing casting industry is developing rapidly, which has a better impact on the stability of the bearing steel market. At present, the demand for high-end bearings is now increasing significantly, such as precision angular contact ball bearings for ball screw bearings, aerospace bearings, precision bearings for machine tools for photovoltaic industry, high-speed electric spindle bearings, rotary table bearings, wind power bearings, rolling mill bearings, high-speed rail bearings. , automotive bearings, pulley bearings for cranes, turbocharger bearings, hydrodynamic bearings, etc.
After more than 50 years of construction and development, China's bearing industry has achieved a small to large, weak to strong development strategy, forming a relatively complete industrial system with a rational production layout, large and medium-sized enterprises coexisting, and complete product categories. Moreover, it has a large production capacity and strong technical strength. At present, China's bearing industry has already had a large economic scale. There are more than 1,400 bearing enterprises in the country, employing more than 300,000 people. In 2011, China's bearing manufacturing industry achieved a total industrial output value of 193.121 billion yuan, an increase of 27.59% year-on-year; sales revenue was 191.907 billion yuan, an increase of 30.30%; total profit was 12.523 billion yuan, an increase of 26.54%.
At present, the basic machinery casting industry such as precision bearings has become a key development industry during the “Twelfth Five-Year Plan†period, and strives to achieve or approach the international advanced level. It is expected that with the support of the policy, by 2015, the sales of the high-end bearing casting industry will reach 222 billion yuan. China's bearing output is expected to exceed 22 billion sets, and the total sales volume is expected to exceed 350 billion yuan, becoming the world's largest bearing production and sales base.
