Abstract: A bearing unit for a wheel has a rotary ring whose raceway surface is hardened by a thermal process. In this bearing unit, the side surface of a fitting flange for fixedly joining a rotary body for braking and a wheel, is formed by working in a predetermined configuration after the raceway surface of the rotary ring has been subjected to the thermal process. The raceway surface of the rotary ring is worked in a predetermined configuration and dimensions on the basis of the side surface of said fitting flange. This bearing unit can restrain disagreeable noises and vibration from being caused upon braking.

Abstract: At a surface opposite to a mounting surface 28 at a part of the mounting flange 13, a projecting part 27 is provided so as to surround the opening part of the mounting holes 23 for press-fitting each stud thereinto. A finishing process of the mounting surface 28 is carried out after the stud 24 is press-fitted into the mounting hole 23.
