Under a certain load, the number of revolutions or hours that the bearing experiences before pitting corrosion is called the bearing life.
At present, our design and manufacturing technology is basically imitated, and our product development capabilities are low.
According to data from the National Bureau of Statistics, in 2011, there were 1,416 enterprises in China's bearing manufacturing industry (annual sales revenue of more than 20 mill
This design was subsequently replaced by rolling bearings, which replaced the original bushings with many cylindrical rollers. Each rolling element was like a separate wheel.
Bearing is an important part of contemporary machinery and equipment.
The radial clearance of the rolling bearing is small, and it can be eliminated by the method of axial preloading, so the operation accuracy is high.
