1. A wheel hub bearing for motor vehicles, comprising:
a hub and a bearing unit in turn comprising:
a radially outer ring comprising an outer raceway,
at least one radially inner ring comprising an inner raceway forming a rolling body contacting portion and a curved section extending from the rolling body contacting portion,
at least one row of rolling bodies between the radially outer ring and the radially inner ring, the hub having a radial stiffening, wherein
the radial stiffening of the hub presents a misalignment with respect to a seat, the misalignment being a distance between a center line axis of the seat of the radially inner ring on the hub and a center line axis of the radial stiffening being less than or equal to 25% of a length of the seat, wherein
the radial stiffening further defines a central portion straddling the center line axis, the central portion axially overlapping, but not extending axially past, the at least one row of rolling bodies, and wherein
the curved section of the inner raceway extends radially away from the at least one row of rolling bodies such that that the rolling body contacting portion of the inner raceway does not extend axially past the at least one row of rolling bodies.
