Rolling-element bearing cage

The invention relates to a rolling-element bearing cage (1) which includes a plurality of cage segments (2, 3, 4) complementary as a circular structure in circumferential direction (U), each cage segment (2, 3, 4) including at least two adjacent receiving pockets (5, 6, 7, 8), each receiving pocket (5, 6, 7, 8) being delimited by two adjacent cage bridges (9, 10, 11, 12), each cage bridge (9, 10, 11, 12) having running surfaces (13, 14) for a rolling element (15) at the surface towards the receiving pockets (5, 6, 7, 8). In order to improve the dynamic characteristics of the rolling bearing with such cage, the running surfaces (13, 14) of at least one receiving pocket (5, 6, 7, 8) are asymmetric relative to a center plane (E) of the receiving pockets (5, 6, 7, 8). 本发明涉及种滚动轴承保持架(1)，其包括多个保持架节段(2、3、4)，所述保持架节段在周向(U)上互补为环形的结构，其中每个保持架节段(2、3、4)具有至少两个相邻的兜孔(5、6、7、8)，其中每个兜孔(5、6、7、8)通过两个相邻的保持架接片(9、10、11、12)限定，其中所述保持架接片(9、10、11、12)在其朝向兜孔(5、6、7、8)的表面处具有用于滚动体(15)的运行面(13、14)。为了改善带有这样的保持架的滚动轴承的动态特性，本发明规定，至少个兜孔(5、6、7、8)的运行面(1
