The invention relates to a rolling bearing cage (1) having a first side ring (2) and a second side ring (3), wherein the two side rings (2, 3) are arranged at a spacing from one another in an axial direction (a) and wherein a number of webs (4) extend between the two side rings (2, 3) in order to form a number of receiving pockets (5) for rolling elements (6) corresponding to the number of webs (4). In order to design the cage such that it is particularly suitable for use at high speeds and allows favourable lubrication, the invention provides that first and second slopes (7, 8) extending at an angle (α, β) to the axial direction (a) at the side rings (2, 3) and/or at the webs (4) are formed on the radially internal surface of the cage (1) in the axial region of the two side rings (2, 3), wherein the radius (r) of the surface of the slopes (7, 8) decreases towards the axial centre (M) of the cage (1), and that third slopes (9) extending at an angle (γ) to the axial direction (a) at the side rings (2, 3) and/or at the webs (4) are formed on the radially external surface of the cage (1) in the axial region of one of the two side rings (2, 3).
