The invention relates to a rolling bearing cage or cage element (1), comprising at least one ridge region extending in an axial direction (a), the at least one ridge region having guiding surfaces (2, 3) for rolling elements (4) on two sides facing away from one another. According to the invention, in order to improve the lubrication of the bearing provided with the cage or the cage element, at least one accommodating space (5) for lubricant is arranged in the rolling bearing cage or cage element (1), wherein a single fluid channel (6, 7) extending in the interior of the rolling bearing cage or cage element (1) leads from the accommodating space (5) to each guiding surface (2, 3), wherein the accommodating space (5) is arranged in the radially outer ridge region and, when viewed in the axial direction (a), has a V-shaped cross-section, wherein the fluid channels (6, 7) open into a region (8) of the guiding surface (2, 3) that is set back from the guiding surfaces (2, 3), wherein the two fluid channels (6, 7) have a rectangular cross-section and extend across the width of the set-back region of the guiding surface (2, 3) and wherein the two fluid channels (6, 7) slope, at an acute angle to the radial direction, from the accommodating space (5) to its outlet at the guiding surface (2, 3). |
