Abstract
A wheel bearing assembly can be assembled easily while maintaining a high reliability of connection between the outer ring and the hub. A hub is fitted into or onto a shaft portion of an outer ring of a homokinetic joint. Ball raceways are formed on the outer ring and the hub at their opposite ends. Balls are arranged in two rows so as to roll along the respective raceways. A bearing outer ring around the outer ring and the hub is supported by the balls. The shaft portion of the outer ring and the hub are press-fitted together with a predetermined interference. They are welded together at one end of their joint area.
