<P>PROBLEM TO BE SOLVED: To achieve a manufacturing method capable of finish-grinding each of first and second outer-ring raceways 5, 6 with better geometric accuracy. Ž<P>SOLUTION: When subjecting each of the first and second outer-ring raceways 5, 6 to a grinding process, the manufacturing method starts the grinding process, with an integral grinding wheel 14a, first on an inner circumferential surface of a shoulder portion 17, thereby stabilizing a feed rate of the grinding wheel 14a. After that, while maintaining the feed rate stable, the manufacturing method starts grinding each of the first and second outer-ring raceways 5, 6. Employing the manufacturing method like this solves the problem. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
