Abstract
An improved rolling bearing is proposed which has a longer life under heavy load and under lubrication with oil containing foreign matters. Its bearing rings and rolling elements are made of carburized steel having an oxygen content of 15 PPM or less and have a deeper surface hardened layer and a higher core hardness. It has a longer life even under lubrication with oil containing foreign matters.
