PROBLEM TO BE SOLVED: To provide a rolling bearing which is excellent in resistance against white peeling while having a fatigue life under a lubrication environment with foreign matters mixed therein just as blister steel, and is suitable for a mine construction machine and a construction machine in particular, at a low cost.SOLUTION: The rolling bearing includes an inner ring having an orbital plane, an outer ring having an orbital plane facing the orbital plane of the inner ring, and a plurality of rolling bodies disposed so as to freely roll between both orbital planes with an outer diameter of the outer ring being 180 mm or more, in which at least one of the inner ring and the outer ring is composed of steel whose carbon content is 0.7 mass% or more, and a specific hardened layer is formed on the orbital plane by induction hardening. |
