Why stainless steel bearings can rust

Stainless steel bearings will rust under certain conditions. Stainless steel bearings have the ability to resist atmospheric oxidation - that is, stainless, but also have the ability to corrosion in media containing acid, alkali, and salt - that is, corrosion resistance.
However, the corrosion resistance of the steel varies with the chemical composition of the steel itself, the interaction state, the conditions of use, and the type of environmental media. Stainless steel bearings have absolutely excellent resistance to corrosion in a dry and clean atmosphere, but moving it to the seashore area will quickly rust in sea fog containing a large amount of salt. Therefore, stainless steel bearings are not any kind of stainless steel. Bearings are resistant to corrosion and rust in any environment.
