Compared with ordinary bearings, stainless steel bearings not only have obvious advantages in materials, but also have stricter control on precision in process and precision than ordinary bearings. In the working process, stainless steel bearings work stably, with low noise and corrosion resistance, achieving high strength and high precision production. It can be used in a wide range of products for general corrosion.
Product Features
The bearing ring and rolling element material are vacuum-quenched and tempered by AISI SUS440C stainless steel (domestic grade: 9Cr18Mo, 9Cr18). The frame material of the cage and seal ring is AISI304 stainless steel (domestic grade: 0Cr18Ni9). Compared with ordinary bearing steel, stainless steel bearings have stronger rust and corrosion resistance. Choose suitable lubricants, dustproof covers, etc., and can be used in the environment of -60 ° C ~ +300 ° C. Stainless steel deep groove ball bearings resist corrosion caused by moisture and several other media. These single row deep groove ball bearings have the same deep bearing groove as the standard deep groove ball bearings made of carbon chromium (rolling bearing) steel, and the degree of fit between the bearing race and the ball is extremely high. Stainless steel bearings are widely used in food processing, medical equipment, and pharmaceutical machinery due to their high mechanical strength and load capacity.

advantage
1. Excellent corrosion resistance: stainless steel bearings are not easy to rust and have strong corrosion resistance.
2, washable: stainless steel bearings can be washed down without having to re-lubricate to prevent rusting punishment.
3, can run on the liquid: due to the materials used, we can run the bearings and housings in the liquid.
4, the depletion speed is slow: AISI 316 stainless steel, no oil or grease anti-corrosion protection. Therefore, if the speed and load are low, there is no need to lubricate.
5. Hygiene: Stainless steel is naturally clean and non-corrosive.
6. High heat resistance: Stainless steel bearings are equipped with high temperature polymer cages or cages that are not in a complete complementary structure and can operate at higher temperatures ranging from 180°F to 1000°F. (Need to be equipped with high temperature grease)
Cause of failure
The main cause of fracture failure of stainless steel bearings is the two major factors of defects and overload. When the applied load exceeds the material strength limit and the part is broken, it is called overload fracture. The main reason for the overload is the sudden failure of the host or improper installation. Defects such as microcracks, shrinkage cavities, air bubbles, large foreign objects, overheated tissue and localized burns of the bearing parts also cause breakage at the defects during impact overload or severe vibration, called defect fracture. It should be pointed out that in the manufacturing process, in the process of re-inspection of raw materials, quality control of forging and heat treatment, and process control, the above defects can be correctly analyzed by instruments, and control must be strengthened in the future. However, in general, the failure of stainless steel bearings that usually occur is mostly overload failure.
