Method of Producing Rolling Bearing Device for Wheel

A method of producing a rolling bearing device for a wheel, wherein the rolling bearing device includes an outer ring, an inner ring, and a plurality of rolling elements, and the outer ring or the inner ring is provided with a brake disk mounting flange having a brake disk mounting surface to which a brake disk is directly or indirectly mounted,

• wherein the method comprises:
• a bearing device and grinding wheel preparing step of preparing the rolling bearing device for the wheel in a state where the outer ring, the inner ring and the plurality of rolling elements are assembled and an annular recess is formed on the brake disk mounting surface, and an annular grinding wheel having a smaller width than a width of the recess in a radial direction;
• and
• a brake disk mounting surface grinding step of grinding the brake disk mounting surface by bringing the brake disk mounting surface into contact with the annular grinding wheel, while the outer ring or the inner ring having the brake disk mounting surface is rotated around a center axis of the inner ring or the outer ring, in a state where the annular grinding wheel has a part overlapping with the recess over an entire region of the annular grinding wheel in the radial direction from an outer periphery to an inner periphery of the annular grinding wheel, in a state where the annular grinding wheel and a region inside the annular grinding wheel do not overlap with the region inside the annular recess, and in a state where a grinding surface of the annular grinding wheel is inclined with respect to the brake disk mounting surface so that a distance between the grinding surface and the brake disk mounting surface grows larger in a direction from the annular recess of the brake disk mounting surface toward an outer edge of the brake disk mounting surface.
