Abstract

A rotary bearing, in particular a large open-centered ring bearing, having two concentric bearing races, of which one bearing race has a groove which is open toward the other bearing race, and the other bearing race has a lug ring that engages in the aforementioned groove. The lug ring can be supported against the groove in the axial and radial directions of the rotary bearing with a plurality of bearing assemblies that include at least two axial bearings mounted on opposite lug ring end faces, and at least one radial bearing that is mounted on an outer surface of the lug ring. The plurality of bearing assemblies have at least one sliding bearing and at least one rolling bearing situated between the lug ring and the groove.
