At the same time, with the continuous advancement of technology and the continuous expansion of applications, the application field of large-size deep groove ball bearings will continue to expand. It can be seen that the application field of large-size deep groove ball bearings is very important, so strictly controlling the production process of large-size deep groove ball bearings is of great significance to ensure the bearing capacity and service life, ensure the smooth operation and reliability of the bearing, improve the adaptability and reliability of the bearing, reduce production costs and improve economic benefits. The specific control process is as follows:

1. Ensure the bearing capacity and service life

Material selection and smelting

As the main material of large-size deep groove ball bearings, the chemical composition, purity, organization and uniformity of bearing steel have an important influence on the bearing capacity and service life of the bearing. Strictly controlling the smelting process can ensure that the chemical composition of the bearing steel meets the standard, reduce non-metallic inclusions, and improve the purity and uniformity of the steel.

Heat treatment process

Heat treatment is a key link that affects the performance of bearing materials. By precisely controlling the heating, insulation and cooling processes, the ideal organization and hardness can be obtained, thereby improving the bearing capacity and wear resistance.

Machining accuracy and surface quality

The dimensional accuracy and surface quality of the bearing have an important influence on the smooth operation, vibration and noise of the bearing. Strictly controlling the processing technology can ensure that the dimensional accuracy and surface quality of the bearing meet the design requirements, reduce friction and wear, and extend the service life of the bearing.

2. Ensure the smooth operation and reliability of the bearing

Reduce friction and wear

By optimizing the bearing geometry, surface roughness and lubrication method, the friction and wear of the bearing during operation can be reduced, and the smooth operation and reliability can be improved.

Control internal stress

Bearings will generate internal stress during processing and heat treatment. If these internal stresses are not controlled, they will affect the operating performance and life of the bearing. Through reasonable processing and heat treatment processes, internal stress can be controlled and eliminated, and the reliability and service life of the bearing can be improved.
