A wheel hub assembly (10) with two rows (C1, C2) of rolling bodies (13) with an axis (A) of rotation and comprising, for each row of rolling bodies (13), with an inner raceway (111, 112) and an outer raceway (121, 122) which are arranged in axially staggered positions in accordance with a respective angle of contact and along a respective load line (11, 12) in order to allow the assembly to support combined loads. The raceways of each row of rolling bodies (13) are provided with respective osculations which are defined by the ratio between the radiuses of curvature of the raceways and the outer diameters of the rolling bodies (13) of the associated row of rolling bodies (13). The osculations of a first row (C1) of rolling bodies (13) of the two rows (C1, C2) of rolling bodies (13) are different from the osculations of a second row (C2) of rolling bodies (13) of the two rows (C1, C2) of rolling bodies (13). |
