Abstract
The invention relates to a rolling bearing arrangement for a rotational connection for a roller/ball combination raceway system, for the purpose of relative movement of a plurality of rotating elements, in particular two rolling bearing rings supported on one another. At least one rolling element raceway is hardened along its annular shape in the contact area between rolling element and rolling bearing ring. The invention is characterized in that provided at the beginning and the end of the at least one hardened rolling element raceway is at least one overlap region which extends along the rolling element raceway, the overlap region comprising a region of lower hardness than the surrounding hardened region, the lower hardness gap region, extending at an inclination through the overlap region.
