What qualities do stainless steel bearing materials require?
1. First of all, the working environment and conditions of stainless steel bearings themselves should be taken into account. Therefore, it is necessary to adopt materials with certain corrosion resistance, that is, the selected materials should 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 extreme pressure additives, which are factors that will corrode bearing materials, therefore, bearing materials need to have corrosion resistance.
2. Stainless steel bearings need to keep running for a long time in the production process, so the material used must have certain wear resistance and excellent wear resistance.
3. In order to meet the requirements of long-term operation, the stainless steel bearings should also have excellent fatigue resistance. Therefore, the material also has such requirements, that is, the ability of material to resist fatigue damage under cyclic loading. At service temperature, the strength, hardness, impact strength and homogeneity of the bearing material are very important to the fatigue resistance.
4. In order to ensure the production accuracy and operation stability, the stainless steel bearing products must 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.
