Rolling bearing material performance requirements depending on the bearing operating characteristics. Generally, the bearing steel should have the following properties:
High contact fatigue strength.
2 high wear resistance.
3 high elastic limit and yield strength.
4 high and uniform hardness.
Certain impact toughness.
6 good dimensional stability.
7 good corrosion performance.
Good process performance.
Bearing materials for the work under special conditions, according to their specific requirements should also have a special performance of their conditions, such as: high temperature, low temperature resistance, corrosion resistance, anti-radiation, anti-magnetic and other characteristics.
