Bearing is an important foundation for all types of machinery and equipment parts, its precision, performance, longevity and reliability of the host precision, performance, longevity and reliability play a decisive role. Mechanical products, angular contact thrust ball bearing are precision products, comprehensive support not only in 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 computer technology and many other disciplines to serve, therefore bearing is a representative national scientific and technological strength of the product.
After the international financial crisis in 2008, the state 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 rapidly expanding sales and profit levels would be enhanced significantly accelerate the development of the industry. According to the National Bureau of Statistics, China bearing manufacturing industry size in 2011 (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% over the previous year.
In recent years, world famous enterprises have entered the Chinese market and establish production bases bearing. The company is not only a global business, and is a global manufacturer, by virtue of their superior brand, equipment, technology, capital and production scale, and domestic enterprises bearing a fierce competition. Domestic enterprises are mainly engaged in manufacturing general Bearing life testing machine, less special and high-end bearing manufacturers, technology is not mature. Therefore, domestic enterprises are to compete with foreign advanced bearing brands, and even beyond, but also need to go through a long period of time in terms of technology development.
Slewing bearing product is very important!
