Important links of bearing production process must be paid attention to, so as not to cause unnecessary damage to bearings:

 

1, forging link

 

Forging link is an important link to ensure the reliability and life of bearings. Raw materials are forged to form blank bearing rings. At the same time, the organizational structure of raw materials becomes more dense and the flow linearity becomes better, so as to improve the reliability and service life of bearings. In addition, the quality of forging process will directly affect the utilization rate of raw materials, and thus affect the production cost.

 

2. Heat treatment

 

Heat treatment is the high temperature treatment of the bearing ring after forging and turning, which directly affects the uniformity of carburizing in the bearing ring, can improve the wear resistance and hardness of the bearing, and is also an important link affecting the reliability and life of the bearing.

 

3, grinding process

 

The bearing ring after heat treatment also needs to be grinded, which is an important link to ensure the bearing accuracy. After grinding, the production process of bearing ring is basically completed.

 

Process flow of bearing inner and outer ring: bar -- forging -- turning -- heat treatment -- grinding -- super finishing -- final inspection of parts -- rust prevention and storage.
