Abstract: A method for increasing load capacity of a surface-hardened rolling bearing raceway of a rolling bearing ring element may involve providing a rolling bearing ring element with an unhardened core region and, at least in certain portions, an outer layer hardened to a surface hardening depth. A rolling bearing raceway may be formed in a region of the hardened outer layer. The method may further involve hard rolling the rolling bearing raceway with a roll. The diameter of the roll is 8 to 25 times the surface hardening depth. 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. The method further involves machining the rolling bearing raceway after the hard rolling.
