Zusammenfassung:	A hub bearing assembly includes a hub (30) made of light metallic material and forming a cylindrical portion (31) and a radially outward extending flange (32). A first tubular inner ring (24) providing a raceway (25) and an inner cylindrical cavity (42) is mounted on the cylindrical portion (31) of the hub (30). A second inner ring (27) is fixed on the first tubular inner ring (24) and provides a second raceway (26). A cylindrical interstice (46) is formed between the cylindrical portion (31) of the hub (30) and the cavity (42) of the first tubular inner ring (24) and contains a brazing material to integrally join the cylindrical portion (31) of the hub (30) to the first tubular inner ring (24).
