Abstract
A rolling bearing comprises a rolling element, an outer ring having an outer circumferential surface portion subjected to surface hardening and an inner circumferential surface portion acting as an orbit of the rolling element, the outer circumferential surface portion being in contact with other members so as to be used as a roll, and an inner ring having an outer circumferential surface portion acting as an orbit of the rolling element. The hardness of a core portion of the outer ring is set to be in a range of from Hv 500 to Hv 650.
