What is the function of bearing forging heat treatment?

2024-08-22

The forging heat treatment of bearings plays a crucial role in the manufacturing process, mainly reflected in the following aspects:

1、 Improve the hardness and wear resistance of bearings

Hardness improvement: Heat treatment, through high-temperature treatment, causes changes in the internal structure of the bearing material, thereby significantly increasing the hardness of the bearing. The increase in hardness helps bearings maintain shape stability and reduce wear when subjected to heavy loads and high-speed rotation.

Enhanced wear resistance: As the hardness increases, the wear resistance of the bearing also increases. This means that bearings can more effectively resist wear and extend their service life during long-term use.

2、 Improve the internal organization of bearings

Organizational densification: During the forging process, the raw material undergoes plastic deformation, resulting in a denser organizational structure and improved flow lines. The subsequent heat treatment further promoted the homogenization of the internal structure, eliminated the internal stress that may be generated during the forging process, and improved the overall performance of the bearing.

Uniformity of carburizing: The carburizing treatment during the heat treatment process can ensure the uniformity of carburizing in the bearing ring, which is crucial for the performance and service life of the bearing.

3、 Improve the fatigue resistance of bearings

Extended anti fatigue life: Bearings need to repeatedly bear loads and rotate during use, which can easily lead to fatigue fracture problems. Heat treatment significantly enhances the fatigue resistance of bearings by improving their internal structure and increasing their hardness, reducing the possibility of fracture and thus extending their service life.

4、 Improve the surface quality of bearings

Eliminating surface defects: During the production process, there may be defects and oxides on the surface of bearings, which can have adverse effects on the performance and lifespan of the bearings. High temperature treatment during the heat treatment process can eliminate these surface defects and oxides, and improve the surface quality of bearings.

Enhanced corrosion resistance: Bearings are easily corroded by external environments during use, leading to surface oxidation and other issues. Heat treatment improves the surface quality of bearings, enhances their corrosion resistance, and enables bearings to function normally under external environmental influences.

5、 Improve the reliability and stability of bearings

Comprehensive performance improvement: Through heat treatment, bearings have significantly improved in hardness, wear resistance, fatigue resistance, surface quality, and other aspects. These performance improvements collectively affect the overall performance of the bearing, enhancing its reliability and stability.

In summary, bearing forging heat treatment plays an irreplaceable role in the manufacturing process of bearings. By using a reasonable heat treatment process, the performance and lifespan of bearings can be significantly improved, ensuring that they can work stably and reliably during use.
