Abstract: An open-centered large rolling bearing having two concentric bearing rings, which are supported against one another in the axial direction of the rolling bearing by means of at least two axial bearings, which are arranged on opposite end faces of a bearing ring. In the radial direction, the bearing rings are supported against one another by at least three radial bearings, which are arranged on inner and outer circumferential sides of a bearing ring.
