摘要: The invention relates to a rolling element bearing (1) that comprises a plurality of balls (4) as rolling elements guided in a cage (5). In snapping pockets (8) in a region between a lateral ring section (6) and the central ball (4) track, between the ball (4) and the adjoining web section (7) and/or the adjoining lateral ring section (6), a lubricant channel (19) is formed which fluidically connects the radial outer side and the radial inner side of said cage (5). In order for the rolling element bearing (1) lubricant supply to be improved the invention suggests that, on the web sections (7), an outer block section (10) is formed on the radial outer side and/or an inner block section (11) is formed on the radial inner side, these projecting relative to the lateral ring section (6), in the radial direction in relation to the bearing axis L, and reducing the available rolling element space between two adjoining balls (4).
