Abstract
A wheel hub configured as a bearing inner ring for an anti-friction bearing includes a central axis of rotation and a body portion having a circular cross section perpendicular to the central axis of rotation. The body portion has a radial outer side and at least one functional surface on the radially outer side, the at least one functional surface including at least one raceway. At least a first functional surface of the at least one functional surface is laser-hardened. Also a related method.
