The core difference between stainless steel bearings and ordinary bearings lies in their materials, which determine their performance in different environments. Ordinary bearings (mainly referring to GCr15 bearing steel) are known for their strength and wear resistance, while stainless steel bearings are primarily valued for their corrosion resistance.

This is mainly due to their distinctly different material properties: Ordinary bearings are made of high-carbon steel, which, through heat treatment, achieves extremely high hardness and excellent wear resistance. Their strong load-bearing capacity and fatigue resistance make them the first choice for high-load, high-speed operation. However, they have almost no rust prevention capabilities and are easily damaged in humid or corrosive environments.

Stainless steel bearings: by adding elements such as chromium to the steel to form a dense oxide film, they possess excellent rust and corrosion resistance. They can also operate at more extreme temperatures.

Bearing steel generally has a higher carbon content to enhance wear resistance, while stainless steel generally has a higher chromium content, exceeding 12%, primarily to utilize its corrosion resistance. Compared to ordinary bearings, stainless steel bearings not only have a significant advantage in material composition but also require much stricter manufacturing processes and precision control.
The main difference between stainless steel bearings and ordinary bearings lies in their corrosion resistance; other aspects are similar.
If the operating environment is acidic or corrosive, it is recommended to choose stainless steel bearings, as their service life will definitely be superior to that of ordinary bearings.
