PROBLEM TO BE SOLVED: To provide a manufacturing method for performing finish machining of a mounting face 26 of a mounting flange 17 by a dry system without causing chips in accordance with machining to improve rotation balance after machining. SOLUTION: While this bearing unit for supporting a wheel is assembled, an outer ring 6 is fixed, and a hub 8 is rotated. At the same time, an outer peripheral face of a back-up roller 30 is abutted on a part of an anti-mounting face 31 of the mounting flange 17 to support the part. In this condition, an outer peripheral face of a roller 32 for molding is pressed against a part where it is aligned with a contact part of the back-up roller 30 and the anti-mounting face 31 in a mounting face 26. Consequently, finish machining of the mounting face 26 is performed based on plastic deformation of the pressed part. By adopting a finish machining method like this, the above task is solved.
