Compared with ordinary bearings, stainless steel needle roller bearings not only have higher requirements for the selection of raw materials but also are more stringent than ordinary bearings in terms of the production process and precision control.
For stainless steel needle roller bearings, the selection of different materials has a great impact on the quality and strength of the produced bearings, because there are many types of stainless steel materials, today we will talk about the importance of raw materials for stainless steel needle roller bearings.
1. Since stainless steel needle roller bearings need to keep running for a long time during use, this requires the material to have high wear resistance and wear resistance performance, otherwise the bearing may break and be damaged in a short period.
2. To ensure that stainless steel needle roller bearings can be used for a long time, the selected stainless steel material should have stability, so that it has high dimensional accuracy when producing bearings so that the bearings have good stability during operation. Stability, especially rolling bearings, which are precision mechanical parts, have high requirements for precision, which cannot be met by general materials.
3. Due to the particularity of the environment in which stainless steel needle roller bearings are used, their materials are required to have good corrosion resistance, especially when we add lubricating oil to the bearings, the lubricating oil will be acidic due to contact with air In addition, the additives in the lubricating oil also have a certain corrosive effect, and the raw materials in bearings do not have corrosion resistance, so they are easy to rust and oxidize during use.
In addition, the materials used for stainless steel needle roller bearings should meet the requirements of strength and hardness and have temperature resistance, fatigue resistance, and impact resistance.
It can be seen that the manufacturers of stainless steel needle roller bearings should not be careless when selecting raw materials. They should carefully select raw materials so that the quality of the produced bearings will not be poor.
