Abstract
Abstract A rolling bearing has at least two bearing rings which are separated from one another by a spacer, and the joints between the spacer and the bearing rings are sealed with sealing rings. The spacer is a disk with flat end faces which extend over the full height of the disk. The outer periphery of the spacer has at least one sealing ring which projects axially over the end faces of the spacer and rests against surfaces of the adjacent bearing ring.
