What are the characteristics of corrosion resistant bearings?

Bearings operating in corrosive media. Stainless steel manufacturing, generally in the oxidizing medium, such as seawater, fresh water, water vapor and humid environment working bearings, or in a certain concentration of acid or alkaline medium working bearings, can be made of stainless steel (9Cr18, 9Cr18Mo) bearing ring and rolling body.

Use 0Cr19Ni9 or 1Cr18Ni9 stainless steel as retainer; If working in corrosive media with higher ambient temperature, bearing rings and rolling materials are mostly high temperature stainless steel bearings (Cr14Mo4).For larger corrosion resistant bearings, semi-martensite and martensite stainless steel, such as 1Cr13, 2Cr13 or 3Cr13, is usually adopted. The stainless steel or beryllium bronze retainers are made after surface nitriding treatment.
