A rolling-element bearing cage includes a plurality of cage segments, each cage segment including at least two adjacent receiving pockets, each receiving pocket being delimited by a front cage bridge having a front running surface for contacting a rolling element and a rear cage bridge having a rear running surface for contacting the rolling element. The front running surface and the rear running surface of at least one of the at least two adjacent receiving pockets are asymmetric relative to a center plane that divides the receiving pocket.
