In the current domestic market, high value-added precision bearing demand and large compound growth rate of around 20% , although the growth speed, great market potential, but at present the vast majority of our production is small-scale and small and medium tapered bearing bearings bearing the above in large-scale production accounted for less than 3%.
Bearing components are fixed and reduce the coefficient of friction in the mechanical load transmission process. In recent years, China's bearing market is expanding , however , China's stainless steel slewing bearing industry is still big but not strong , the data show that in 2012 China's bearing industry sales reached 142 billion yuan , mainly in the production of low-end bearings, and high-end bearings are mainly rely on imports . This also led our country there is a big gap from the major industrial countries .
Backing bearings are particularly thick outer ring of the rolling bearing, when used to form a group to be mounted on the shaft of a stationary support rollers. Pressure on the work roll through the intermediate roller and the support roller is passed to the system to the rack through the saddle. Generally used for multi-roll cold rolling mill equipment can also be used for other occasions, such as straightening machine.
