What qualities are required for the materials used in the manufacture of stainless steel bearings?
1. The first thing to consider is the working environment and conditions of the stainless steel bearing itself, so 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 and produce acidic substances when it is used in the atmosphere, and most lubricating oils also contain extreme pressure additives, which are all factors that will corrode the bearing materials. Therefore, the bearing The material needs to be corrosion resistant.
2. During the production process, the stainless steel bearings need to keep running 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 such requirements, that is, the ability of the material to resist fatigue damage under cyclic loading. At the service temperature, the strength, hardness, impact strength and organizational uniformity of the bearing material are very important for fatigue resistance.
4. In order to ensure the production accuracy and operation stability, the stainless steel bearing products produced must maintain good dimensional stability. For example, rolling bearings are precision mechanical parts, and their accuracy is calculated in microns. Therefore, in order to ensure the dimensional accuracy of the bearing, the steel used for the bearing should have good dimensional stability.
