Abstract

PURPOSE: To aim at improvement of heat resistance and corrosion resistance of a rolling bearing by making a rolling body with ceramics mainly consisting of nitriding silicon and applying corrosion resistance film made from chronium compound etc., to an inner ring and on outer ring.
CONSTITUTION: An inner ring 7 and an outer ring 8 are made of bearing steel etc., and a corrosion resistance film made of vanadium compound, chronium compound, etc., is applied to its whole surface. A cylindrical roller 9 as a rolling body is made from nitriding silicon by a pressure sintering method such as hot press, etc. Since the nitriding silicon is hard silicon member, yttria as sintering assistant and, as occasion demands, aluminum oxide are added the, etc., less than 10%. Further, it leads to the most good result on heat resistance and corrosion resistance to form the inner ring 7 and the outer ring 8 with ceramic.
