Abstract: A rolling bearing, in particular a center-free large rolling bearing, having two concentric ball races with one ball race comprising a groove open toward the other ball race and the other ball race comprising a scraper ring engaging into the groove, wherein the scraper ring is supported at the groove in the axial direction of the rolling bearing by at least two axial bearings arranged at oppositely disposed scraper ring front sides and wherein the scraper ring is supported in the radial direction by at least one radial bearing which is arranged on a scraper ring jacket surface. The scraper ring is supported in the axial direction at the groove by a third axial bearing, wherein two axial bearings are arranged at the same side of the scraper ring at separate raceways offset from one another in the axial direction of the rolling bearing.

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.
