Slewing bearings are rotating components used in various industrial and mechanical equipment for a wide range of applications, such as in bridges, large machinery, railway vehicles, and tunneling machines among others. The production of slewing bearings must observe strict controls on the manufacturing process and technical aspects because they play a vital role in equipment performance and safety. Surface heat treatment of the bearing raceway, also known as raceway induction quenching, is an essential process in slewing bearing manufacturing.

Heat treatment is a process whereby metal materials are subjected to certain temperature ranges to change their structure and properties through heating and cooling. For raceway surface heat treatment of slewing bearings, quenching and tempering are the most common methods used. In quenching process the raceway is heated to a high temperature, and then rapidly cooled to achieve a certain hardness, which leads to increased bearing capacity. The tempering process is the post-quenching treatment that adjusts the hardness, toughness, and fatigue resistance of the raceway, ultimately improving the overall performance of the slewing bearing.

The advantages of using heat treatment methods for slewing bearing raceway surface treatment include:

1. A high level of hardness is achieved, increasing bearing capacity and wear resistance.

2. A protective layer for the raceway is created, reducing the risk of surface fatigue and friction damage.

3. Improved surface quality of the raceway reduces uneven surfaces and defects.

4. Increased life of the raceway, reducing the frequency of slewing bearing replacements and effective control production and operational costs.

In conclusion, surface heat treatment of the raceway by using quenching and tempering methods can increase the hardness, toughness, wear resistance, and life of slewing bearing. This ensures effective operation of equipment. With the development of technology and advanced manufacturing approaches, we believe that slewing bearings will have even broader applications that ensure safety while providing excellent performance in various fields.
