What are the basic properties of the materials used for stainless steel bearings

As you should know, the reason why stainless steel bearings have many excellent properties is not only because of the strict requirements for the manufacturing process, but also because the selected materials have good performance. What are the basic requirements for materials?
Considering the working environment conditions, the materials used are required to have corrosion resistance, that is, the materials have good corrosion resistance. In addition, when lubricating, the lubricating oil will gradually oxidize in the atmosphere to produce acidic substances, and most lubricating oils also contain additives, which will corrode the bearing materials. Therefore, the bearing materials need to have corrosion resistance.
Secondly, according to the operation characteristics of stainless steel bearings, the materials used need to be firm because they need to keep running for a long time in the production process.
Third, in order to meet the requirements of long-term operation, the products should also have excellent fatigue resistance. Therefore, materials also have such requirements, that is, the ability of materials to resist fatigue damage under cyclic load. At the service temperature, the strength, hardness, impact strength and organizational uniformity of bearing material are very important to the fatigue resistance.
Fourth, for the sake of production accuracy and operation stability, the products made must maintain good dimensional stability.
In addition to the above requirements, the manufacturing process requirements and material quality requirements for stainless steel bearing products are very strict. The commonly used materials shall also have good rust prevention performance, good process performance, etc.
