Abstract: A sealing assembly including at least one first annular shield having a sleeve portion integral in use with a rotating member and a flange portion, which radially and overhangingly extends from the sleeve portion. Preferably, a second annular shield is arranged in front of the first shield with the interposition of an annular seal; wherein the sleeve portion of the first shield is delimited by a conic-truncated lateral mounting surface having a tapering facing so as to have a greater diameter arranged on the side of the flange portion and intended to couple in use with a mounting seat of the rotating member formed by a shallow recess delimited by a conic-truncated bottom wall having the same tapering as the lateral mounting surface and by an axial shoulder which is arranged on the side opposite to the flange portion.

Abstract: Arrangement including a portion of a radially outer lateral surface of an inner ring of wheel hub having an annular step formed on a constant velocity joint. The step is adapted to receive a first shield, a flange portion that radially extends to protrude towards an outer ring of a wheel hub, in front of a flange portion of a second shield, from a first end of a sleeve portion of the first shield facing on the side opposite of the constant velocity joint and axially protrudes from the inner ring and towards the joint, defining a tubular element arranged straddling wheel hub and an outer ring of the constant velocity joint, having an opposite second end, supporting an annular seal; an annular signal generating insert covers a face of the flange portion, wherein a radially inner annular part of face defines a thrust shoulder for mounting the first shield.

Abstract: A device including a sealing assembly having a first annular shield constrainable to a rotating first member, a second annular shield facing the first shield and constrainable to a stationary second member, and an annular seal supported by the first shield and provided with annular lips cooperating with the second shield. The device has a signal generator device having a third shield constrainable to the first member and an annular signal generator element arranged facing the first and the second shields; wherein the first shield has a flange portion, having on a side of the first shield, a first and a second L-fold in opposite directions which delimit a first annular surface facing the annular lips and the second shield; wherein the annular signal generator element is delimited towards the second shield by a second annular surface facing the annular lips forming an obtuse angle with the first annular surface.
