A comprehensive engineers' reference source for radial ball bearings and thrust ball bearing




Bearings are susceptible to corrosion and should be kept in a dry environment. The lubricant in a bearing will provide some measure of corrosion resistance to the internal raceways, but the acid from skin can corrode the outer surfaces. 52100 chrome steel bearings will quickly corrode if the lubricant is cleaned out, so bearings made from this material should never be used "dry".
