Rolling bearing cage or cage element

A rolling-element bearing cage or cage element, comprising:

• at least one axial bridge region having a first guide surface and a second guide surface facing away from the first guide surface, the first guide surface and the second guide surface being configured to guide rolling elements, the first guide surface and the second guide surface each including a recessed region located axially between first and second non-recessed regions,
• at least one receiving space in a radial outer surface of the rolling-element bearing cage or cage element configured to receive lubricant, the at least one receiving space having a substantially V-shaped cross section, and
• a single first fluid channel having a first longitudinal axis extending from the at least one receiving space to the recessed region of the first guide surface and a single second fluid channel having a second longitudinal axis extending from the at least one receiving space to the recessed region of the second guide surface,
• wherein the first fluid channel and the second fluid channel each have a rectangular cross section,
• wherein the first fluid channel has an axial width substantially equal to an axial width of the recessed region of the first guide surface and the second fluid channel has an axial width substantially equal to an axial width of the recessed region of the second guide surface,
• wherein the first longitudinal axis makes a first acute angle with a radial direction and the second longitudinal axis makes a second acute angle with the radial direction, and
• wherein an axial width of the receiving space is substantially equal to an axial width of the recessed region of the first guide surface.
