<p>PROBLEM TO BE SOLVED: To provide an angular contact ball bearing with a retainer having a plurality of pocket radially passing through a peripheral surface of an annular body arranged at predetermined intervals in a circumferential direction of the annular body, which makes it easier for grease attached to an inner peripheral surface of the annular body constituting the retainer to be supplied to balls.SOLUTION: An angular contact ball bearing of the present invention includes an outer ring 1, an inner ring 2, balls 3, a retainer 4, and a non-contact seal 5 and is used by disposing grease in a space formed by these components. The retainer 4 has, on an inner peripheral surface of an annular body, a tapered surface (lubricant supply surface) 42 that allows lubricant to flow from axially opposite ends to a pocket 41.</p> |
