Through 50 years of construction and development of China's bearing industry has achieved a small to a great weak to strong development strategy formed the production layout is reasonable, medium Slewing Bearing and small enterprises co-exist, relatively complete product of relatively complete industrial system. And with a larger production capacity and strong technical strength.
At present, China 's bearing industry has had a larger economic scale enterprises in the country bearing more Tapered roller bearings than 1,400 employees in about 30 million people. 2011 China's bearing manufacturing industry to realize an annual industrial output value of 193.211 billion yuan , an increase 27.59% ; sales revenue of 191.097 billion yuan year on year increase of 30.30% ; total profit of 12.523 billion yuan year on year increase of 26.54% at present precision bearings and other basic mechanical casting industry has . a national focus on the development of " second five" industry and strive to reach or approach international advanced level. Under the support of the policy is expected to end in 2015 bearing the foundry industry sales reached 222 billion yuan or so . China's bearing production is expected to total sales of over 22 billion sets of more than 350 billion yuan is expected to become the world's largest bearing manufacturing and sales base. So late bearing steel market outlook optimistic .
