description A hub-bearing assembly provided with a bearing unit and a rotatable rotor-hub. The bearing unit includes a stationary radially outer ring, a couple of rotatable radially inner rings, and a double row of rolling elements, wherein the rolling elements are interposed between the outer ring and the inner rings, whose centers are located along a first circle having a radius, with respect to a symmetry axis of the assembly. The rotor-hub is made of a light alloy. A tubular portion is assembled on top of the radially inner rings. The tubular portion is steadily fixed a flange portion, axially external and includes a plurality of fixing holes. Axes of the fixing holes are located along a second circle defined by a radius respective to the symmetry axis of the assembly. The radius of the first circle (rolling elements) is greater than the radius of the second circle (fixing holes).
