The invention relates to a rolling element bearing having at least one inner bearing inner and at least one outer bearing ring. Rolling elements are arranged between the inner ring and the outer ring, and the rolling elements are guided by a cage. To improve the lubrication of the bearing the invention proposes that the cage includes at least one opening, preferably a bore. The opening penetrates the cage from a radial inner surface to a radial outer surface.
