Bearing is a kind of modern machinery and equipment vital parts. Its main function is to support the
mechanical rotating body to reduce equipment in the transmission process, mechanical load coefficient
of
friction. Mechanical products, bearings are precision products, requires not only a comprehensive supp-
ort mathematics, theoretical physics and many other disciplines, but also materials science, heat trea-
tment technology, precision machining and measurement technology,digital technology and efficient nu-
merical methods and powerful computers technology and many other disciplines to serve,so the bearing
is a representative of the national scientific and technological strength of the product.
Prospects bearing industry according to industry research group Institute data show that in 2011 the
scale of China's bearing manufacturing industry (annual sales income of 20 million yuan or more)
companies a total of 1416 companies, total industrial output value of 193.211 billion yuan, up 27.59
percent; sales income of 191.097 billion yuan, an increase of 30.30%; total profit of 12.523 billion
yuan,an increase of 26.54 percent over the previous year bearing industry annual main business income
142 billion yuan, an increase of 20%.
During the second five, the national macro-economic policies will continue to show the effect of the
development of the national economy will boost investment in infrastructure, thus promoting the deve-
lopment of metallurgy,electric power, construction machinery, building materials, energy and other
while the state has adopted ten industrial revitalization planning, the development of the automotive,
aerospace, machine tools, wind power and other industries to provide policy support, industry demand
for these bearings will be gradually expanded. With the development of the host country while bear-
ing industry, bushings product mix will change, its igh-end products in the product increased the
proportion, the sales price will also increase,expected by 2015, China's bearing production is ex-
pected to more than 28 billion units , the main business income is expected to reach 210 billion yuan
becoming the world's largest bearing production and sales base
