Abstract: A sealing device including an annular reinforcing insert couplable with a wheel hub in use and an annular sealing element carried by the reinforcing insert and including at least one sealing lip cooperating with a spacer carried by a wheel support pin in use; the reinforcing insert delimits an annular chamber arranged directly adjacent to the annular sealing element in axial direction, and the device further includes a shield mounted in floating manner with radial and axial play in the annular chamber, including a first radial end, which extends to the lip and couples in forced manner with the spacer in use, and a second radial end, opposite to the first, which cooperates with the reinforcing insert and with the annular sealing element to create a labyrinth seal in the annular chamber interposed in use between the annular lip and an environment (E) external to the wheel hub.
