    摘要： A bearing seal is provided which can be easily fitted into a seal groove formed in an outer race, and be kept firmly mounted to the outer race. First detent ribs (44) and second detent ribs (45) are formed on both surfaces of one side of a seal base plate (42) made of rubber and having the shape of a stripe. When one side of the seal base plate (42) is fitted into the seal groove (3) formed in the inner diameter surface of the outer race (1), the first and second detent ribs (44), (45) come into elastic contact with the side surfaces (3a, 3b) of the seal groove (3), respectively, so as to prevent the bearing seal from being pulled out of the seal groove (3). Thus, it is possible to keep the bearing seal stably mounted to the outer race.

    摘要： Provided is a double-row rolling bearing (1), including: an outer member (2) having two raceway surfaces (6, 6) on an inner circumference thereof; an inner member (3) having two raceway surfaces (7, 7) on an outer circumference thereof, the inner member (3) being arranged on an inner side of the outer member (2); two rows of rolling elements (4, 4) assembled into a space between each of the two raceway surfaces (6, 6) of the outer member (2) and each of the two raceway surfaces (7, 7) of the inner member (3); and a retainer (5) for retaining the rolling elements (4), any one of the outer member (2) and the inner member (3) including a pair of raceway rings (3a, 3b), both the pair of raceway rings (3a, 3b) being fastened with a fixing bolt (16), the pair of raceway rings (3a, 3b) having positioning holes (13a, 13b) into which a positioning member (14, 14') is fit-inserted, to thereby suppress misalignment in a radial direction of the pair of raceway rings (3a, 3b).
