The basic performance requirements of a rolling bearing for a material depend on the operating characteristics of the bearing. In general, steel for bearings should have the following properties:
1. High contact fatigue strength.
2. High wear resistance.
3. High elastic limit and yield strength.
4. High and uniform hardness.
5. A certain impact toughness.
6. Good dimensional stability.
7. Good corrosion inhibition performance.
8. Good process performance.
For bearing materials working under special conditions, according to their specific requirements, they should also have special properties suitable for their conditions, such as: high temperature resistance, low temperature resistance, corrosion resistance, radiation resistance, anti-magnetic properties.
