Heat treatment


Heat treatment is a key process to improve the internal quality of bearings
The main purposes of heat treatment are:
1 Through heat treatment to make the material structure change, improve the mechanical properties of the material.
2 Improve the internal quality of the bearing (wear resistance, strength and toughness), thereby improving the service life of the bearing.
