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.
