The manufacturing process of the bearing has a close relationship with the use of the bearing, quality, performance and service life. If the bearing has any accidents in the manufacturing process, the final manufactured bearing cannot be used normally, and the latter is directly eliminated. Off, so we must pay attention to the bearing production process, this is very important, China Bearing Network tells you about the important aspects of the bearing production process according to experience.

Important aspects of the bearing production process must be taken care of, so as not to cause unnecessary damage to the bearing:

1. Forging link

The forging process is an important part to ensure the reliability and life of the bearing. After the raw materials are forged, the bearing ring blank is formed. At the same time, the organizational structure of raw materials has become even more

Dense and streamlined, which improves bearing reliability and service life. In addition, the quality of the forging process will directly affect the utilization rate of raw materials, thus the production cost.

Have an impact.

2, heat treatment

In the heat treatment process, the bearing ring after forging and machining is subjected to high temperature treatment, which directly affects the uniformity of carburization in the bearing ring, and can improve the wear resistance and hardness of the bearing.

It is also an important part of the reliability and life of the bearing.

3. Grinding process

The heat-treated bearing ring also needs to be ground, which is an important part to ensure the accuracy of the bearing. After the grinding process, the production process of the bearing ring is basically completed.

Bearing inner and outer ring process: bar - forging - car processing - heat treatment - grinding processing - super finishing - final inspection of parts - anti-rust storage.
