ROLLING BEARING

摘要

A rolling bearing excellent in corrosion resistance and long in service life for use in air planes, wherein the component parts are formed of an alloy steel containing at least 7.0 wt.% and up to 16 wt.% of Cr, an element, which is required to enhance a rolling fatigue life at high temperatures by stabilizing retained austenite and is most effective in giving corrosion resistance to steel, and having at least 6%, preferably up to 35% of retained austenite on the surface of a finished product, thereby improving a corrosion resistance and service life.
