PROBLEM TO BE SOLVED: To further improve the bearing cooling effect of a rolling bearing through which an ambient fluid pass axially.SOLUTION: A rolling bearing comprises: an inner ring 2; an outer ring 4; a plurality of rolling elements 6; and a holder 8, a fluid axially passing through a space between the inner ring 2 and the outer ring 4, the rolling bearing being configured so that the holder 8 includes a plurality of holder segments 10 and support rings 22 annularly holding the holder segments 10, each holder segment 10 includes a pocket 12 and a guide surface 14, and a fluid passage 24 is formed between the adjacent holder segments 10, thereby accelerating an ambient fluid to pass through the fluid passage 24 to improve a bearing cooling effect.SELECTED DRAWING: Figure 1 |
