Abstract
A sealing device for a wheel hub assembly having an outer ring and an inner ring. The sealing device includes a first (stationary) annular shield and a second (rotating) annular shield, each having a journalling portion and a flange portion radially extending in cantilever fashion from the journalling portion and towards the other shield; and an annular sealing element carried by the first shield and provided with a plurality of annular sealing lips. The first shield is coupled radially on the outside of the outer ring. The second shield flange portion includes a radially outer annular stretch opposite the journalling portion, extending axially towards the first shield and is incurved radially from the exterior towards the interior, on the side opposite the first shield, forming a U-arranged parallel to a common symmetry axis of the first and second shields, having a concavity thereof facing the side opposite the first shield.
