The pump (1) has a rapidly rotating rotor (2, 3) supported by a roller bearing with an inner ring (20) and an outer ring (21), a cage (22) between them and a roller body (23) in an intermediate space between the inner and outer rings. The cage has a helical groove in a section of its surface facing the inner ring to ensure a continuous feed of a lubricant to the roller body. |
