摘要： A support bearing assembly includes a plural rows of rolling elements (5) between opposed raceway surfaces (3, 4) of outer and inner members (1, 2), respectively. The inner member (2) is formed from a hub unit (9) and an inner ring (10) mounted on an outer periphery of an inboard end portion thereof. An annular stepped area (16) is provided in an inner periphery of the inboard side of the inner ring. A crimped portion (9b) engageable with the stepped area (16) is provided on an inboard end of the hub unit (9) and has a cylindrical shape prior to a crimping process. By setting the amount of change in an inner diameter of the inboard end of the crimped portion (9b) within a preset range when a crimping punch is driven in, the amount (D) of radially outward augmentation of the crimped portion is regulated.
