Production process of bearings

1. Forge link

The forging link is an important link 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 organization structure of raw materials becomes more dense and more linear, which can improve the reliability and service life of bearings. In addition, the quality of the forging process will also directly affect the utilization rate of raw materials, thus having an impact on the production cost.

2. Heat treatment link

The heat treatment link is the high temperature treatment of the forged and car-processed bearing ring, which directly affects the uniformity of carburization 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 and processing link

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

Bearing inner and outer ring process: bar —— forging —— car processing —— heat treatment —— grinding —— super finishing —— final inspection of parts —— antirust in storage
