Bearing hardness is also one of the testing standards for measuring bearings. In the bearing production line, each process is very important, and each step in the production process of the bearing is very important.
Hardness is one of the important indicators of rolling bearings. It is closely related to the material's contact fatigue strength, abrasion resistance, and elastic limit. Self-connection affects the hardness of rolling bearings. Generally, it depends on the bearing load and size, bearing size and wall thickness. To determine the overall situation. The hardness of rolling bearings should be appropriate. Too large or too small will affect the bearing life.
As we all know, the main failure form of rolling bearings is contact fatigue. If the bearing parts lack a certain degree of toughness, the bearing will be damaged due to brittle fracture when the load is cut: Therefore, according to the specific conditions of the bearing and the damage method To determine the hardness of the bearing. Due to fatigue braking or poor abrasion resistance, bearing accuracy is lost. Bearing parts should use higher hardness; for bearings that bear large impact loads (such as rolling mill bearings, railway shafts, Qihua automobile bearings, etc.), the hardness should be appropriately reduced. It is necessary to improve the toughness of the bearing.
