As an important part of our contemporary mechanical equipment, the main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.
The early form of linear motion bearings was to place a row of wooden poles under a row of skid plates. Modern linear motion bearings use the same working principle, but sometimes use balls instead of rollers. The simplest rotary bearing is a bushing bearing, which is just a bush sandwiched between the wheel and the axle. This design was subsequently replaced by rolling bearings, which replaced the original bushings with many cylindrical rollers, each of which was like a separate wheel.
According to data from the National Bureau of Statistics, my country’s bearing output is expected to exceed 28 billion sets by 2015, and its main business income is expected to reach 210 billion yuan, making it the world’s largest bearing production and sales base.
Therefore, in my experience, bearing manufacturers are still a very promising industry. Of course, because the production requirements of bearings will be relatively high, it is necessary to become a bearing supplier with certain skills and capabilities, and certification is necessary.xsjbearing.com
