There are three main reasons for the cracking of the bearing steel ball:
1. The steel ball is cracked during use after being installed inside the bearing, and the cracking direction is the material rolling direction.
2. There are obvious loose bands in the core of the steel ball. The banded carbides exceed the standard and the surface contains abnormal elements such as oxygen, calcium and magnesium. In addition, the strip depth is about 0.25 mm, thereby determining the existence of shrinkage pores in the core of the steel ball, which is a metallurgical defect, which is also the main cause of cracking of the steel ball during use.
3. The quenching and tempering of the steel ball is overheated to increase the brittleness, reduce the compressive strength, and make the steel ball more susceptible to cracking.
