1. The first thing to consider is the working environment and conditions of the stainless steel bearing itself. Therefore, it is required to use a material with certain corrosion resistance, that is, the selected material needs to have good corrosion resistance. Moreover, when lubricating it, the lubricating oil will gradually oxidize when used in the atmosphere to produce acidic substances, and in most lubricating oils, it also contains extreme pressure additives, which are factors that will corrode the bearing material, therefore, the bearing Materials need to be corrosion resistant.
2. In the production process, its stainless steel bearings need to be kept in operation for a long time, so the materials used must have certain wear resistance and excellent resistance to wear.
3. In order to meet the requirements of long-term operation, the stainless steel bearing produced should also have excellent fatigue resistance. Therefore, the material also has the requirement that the material resists fatigue damage under cyclic loading. At the temperature of use, the strength, hardness, impact strength and tissue uniformity of the bearing material are important to combat fatigue.
4. In order to ensure production accuracy and stability of operation, the stainless steel bearing products produced must maintain good dimensional stability. For example, rolling bearings are precision mechanical parts whose accuracy is in micrometers. Therefore, in order to ensure the dimensional accuracy of the bearing, the steel material used for the bearing should have good dimensional stability.
