What is bearing steel bearing? How about its performance?

Bearing steel is the raw material of traditional bearing. According to the material, the bearing can be divided into steel bearing, stainless steel bearing and aluminum alloy bearing. Bearing steel has very strict chemical composition requirements, so the chemical characteristics of bearing steel are very stable, and the batch production will not have much difference. Today, I'd like to introduce the steel bearing and its performance!

1、 What is bearing steel bearing

Generally speaking, bearing steel is called bearing steel. Bearing steel, also known as high carbon chromium steel, contains about 1% carbon and 0.5% - 1.65% chromium. The bearing steel can be divided into six types: high carbon chromium bearing steel, chromium free bearing steel, carburized bearing steel, stainless bearing steel, medium and high temperature bearing steel and diamagnetic bearing steel.

Bearing steel is used to make balls, rollers and bearing rings. Bearing steel has high uniform hardness and wear resistance and high elastic limit. Bearing steel is one of the strict steel grades in all steel production because of its strict requirements on chemical composition uniformity, content and distribution of non-metallic inclusions and carbide distribution.

2、 Performance requirements of bearing steel

In order to meet the above requirements for the bearing force of the moving shaft, the following basic performance requirements are put forward for the bearing steel materials:

1. High contact fatigue strength;

2. After heat treatment, it should have high hardness or meet the requirements of bearing performance;

3. High wear resistance and low friction coefficient;

4. High elastic limit;

5. Good impact toughness and fracture toughness;

6. Good dimensional stability;

7. Good antirust property;

8. Good cold and hot working performance.

The above is the introduction of bearing steel bearing and its performance description, we all understand it! If you want to know more about bearings, you can pay more attention to our website.
