1. A method for increasing a load capacity of a surface-hardened rolling bearing raceway of a rolling bearing ring element, the method comprising:
providing a rolling bearing ring element that has an unhardened core region and, at least in certain portions, an outer layer hardened to a surface hardening depth, with a rolling bearing raceway being formed in a region of the hardened outer layer;
hard rolling the rolling bearing raceway with a roll, wherein a diameter of the roll is 8 to 25 times the surface hardening depth, wherein a surface pressure prevailing in a rolling contact between the roll and the rolling bearing raceway during the hard rolling is between 2000 MPa and 3300 MPa; and
machining the rolling bearing raceway after the hard rolling.
