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.
