A device (1) including: a sealing assembly (4) including a first annular shield (10) constrainable to a rotating first member, a second annular shield (11) facing the first shield and constrainable to a stationary second member, and an annular seal (12) carried by the first shield and provided with annular lips cooperating with the second shield; and a signal generator device (7) including a third shield (16) constrainable in use to the first member and an annular signal generator element (17) arranged at least partly facing the first and the second shields; wherein the first shield has a flange portion (19) having on the side of the fitting portion (18) of the first shield a first and a second L-fold (24, 25) in opposite directions which delimit a first annular surface (26) facing the annular lips and the second shield; and wherein the annular signal generator element is delimited towards the second shield by a second annular surface (27) facing the annular lips which forms an obtuse angle with the first annular surface. |
