Stainless Steel Bearing Material Should Have What Basic Performance Requirements

As we all know, the reason why stainless steel bearings have many excellent properties is not only because of the strict requirements for the production process, but also because the selected material itself has good performance. So when making stainless steel bearings, what are the basic requirements for the material?
1. Taking into account the working environment conditions of stainless steel bearings themselves, the materials used are required to have certain corrosion resistance, that is, the materials have good corrosion resistance. And when it is lubricated, the lubricating oil will be gradually oxidized when used in the atmosphere, producing acidic substances. Moreover, most lubricating oil also contains extreme pressure additives, which will corrode bearing materials. Therefore, bearing materials need to have corrosion resistance.
2. combined with the operation characteristics of stainless steel bearings to analyze, because it needs to keep running for a long time in the production process, so the material used should have a certain wear resistance, and has excellent resistance to wear.
3. In order to meet the requirements of long time operation, the stainless steel bearings made should also have excellent fatigue resistance. Therefore, the material also has such requirements, that is, the ability of the material to resist fatigue damage under cyclic load. In the use of temperature, bearing material strength, hardness, impact strength and uniformity of the organization against fatigue is very important.
4. in order to ensure production accuracy and operation stability, the production of stainless steel bearing products to maintain good dimensional stability. For example, rolling bearings are precise mechanical parts whose accuracy is calculated in microns. Therefore, in order to ensure the dimensional accuracy of bearings, the steel used in bearings should have good dimensional stability.
In addition to the above requirements, in fact, the production process requirements and material quality requirements of stainless steel bearing products are very strict. Usually used materials should also have good rust resistance, good process performance, etc. In this way, the durability and accuracy of stainless steel bearings can be guaranteed.
