Abstract

A rolling bearing with an inner ring and an outer ring which is rotatable about a rotation axis relative to the inner ring, or with an outer ring and an inner ring which is rotatable about a rotation axis relative to the outer ring, and with at least one sealing element arranged between the inner ring and the outer ring for sealing an interior of the rolling bearing which can be filled with a lubricant. The rolling bearing includes a conveying element for conveying the lubricant which is arranged on the one of the inner ring and outer ring so as to be rotatable about the rotation axis of the rolling bearing and in such a way that a play exists between the conveying element and the other of the inner ring and outer ring.
