A rolling-element bearing includes inner and outer rings and a cage between the rings, the cage having a plurality of cage segments with lateral boundary walls defining a receiving pocket for a rolling element having a diameter Dw, the pockets being dimensioned such that in a load-free state the rolling elements are positionable in the receiving pockets with a circumferential clearance (c) on the pitch circle between adjacent boundary walls of the pocket such that the clearance satisfies the relationship: cmax≧c≧Cmin, where: cmin=0.01*Dw−0.5 mm and cmax=0.02*Dw−0.4 mm, and wherein the diameter (Dw) of the rolling-element bearing is at least 50 mm.
