PROBLEM TO BE SOLVED: To provide a matched mounting angular contact ball bearing capable of suppressing slip between an inner ring and rolling elements of an angular contact ball bearing which does not bear axial loads.SOLUTION: Each of a first angular contact ball bearing 11 and a second angular contact ball bearing 21 which constitute the matched mounting angular contact ball bearing 10, includes an outer ring having an outer ring raceway in an inner diameter surface, an inner ring having an inner ring raceway in an outer diameter surface, a plurality of rolling elements arranged rollably between the inner ring raceway and the outer ring raceway, and a retainer which retains the rolling elements at prescribed intervals along a circumferential direction. The matched mounting angular contact ball bearing is constitute by combining the first angular contact ball bearing 11 and the second angular contact ball bearing 21. The first angular contact ball bearing 11 bears axial loads and the second angular contact ball bearing 21 does not bear axial loads. At least the retainer 24 of the second angular contact ball bearing 21 is an inner ring guide type. |
