Abstract: A cover for a wheel-hub bearing made of plastic is provided. The cover includes an end wall that is arranged transversely with respect to a central axis (X) and a cylindrical mounting wall, which extends axially from one side of the end wall around the axis (X). The cover also includes a snap-action step that projects in a radially outwards direction from the cylindrical wall for locking the cover on a tubular appendage of the bearing a resilient ring that is arranged between an annular shoulder portion of the cover and the tubular appendage to exert a resilient recall action on the snap-action step.

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 sealing device for a hub-wheel assembly that includes a rolling bearing is provided. The sealing device being has a screen assembled on an outer ring of the bearing and has an annular cylindrical wall, having an internal lateral surface press fit along an external lateral surface of a collar of the outer ring. The internal surface has a respective inner diameter (Di) and the external lateral surface has a respective outer diameter (De). A static sealing element is constrained to the screen; the ratio of the interference between inner diameter (Di) and outer diameter (De) over a screen thickness ranging between 0.22 and 0.5; a coupling length (L, L?) between the internal lateral surface and the external lateral surface is equal or greater than 5 mm; and a ratio between outer diameter (De) of the external lateral surface and coupling length (L, L?) ranging between 1 and 1.19.

Abstract: An assembly providing a first annular shield including a sleeve portion integral with a rotating member and with a flange portion, which radially extends to protrude from the first sleeve portion; a second annular shield having a sleeve portion integral with a stationary member and with a flange portion that radially extends to protrude on the opposite side of the sleeve portion of the first shield and facing the flange portion; and an annular seal, which the flange portion of the first shield ends with an L-shaped annular portion that protrudingly radially and axially extends out of an annular gap delimited between the rotating and stationary members to define an L-shaped channel in radial section having constant width and forming a first labyrinth seal; the channel leads into an annular recess, delimited between the second shield and a first lip of the annular seal without contacting the first shield.

Abstract: An arrangement including a first and second sealing assembly disposed between an inner ring and an outer ring of the wheel hub and straddling the wheel hub and an outer ring of a constant velocity joint, and an annular step formed on the side of the constant velocity joint on a radially outer lateral surface of the inner ring, in a position adjacent to a sleeve portion of a first shield of the first sealing assembly from a flange portion radially extends so as to protrude towards the outer ring, the flange portion being provided towards the constant velocity joint with a signal generating element (19) consisting of an annular insert; an end of a tubular core of the second sealing assembly is fitted angularly onto the step and is radially externally provided with an L-shaped edge arranged within the step and radially under the annular insert.

Abstract: An arrangement including a portion of a radially outer lateral surface of an inner ring of wheel hub on which an annular step is formed on the side of a constant velocity joint. The step is an L-shaped fold of a sleeve portion of a first shield that is protrudingly mounted, a flange portion of which shield radially extends so as to protrude towards an outer ring of a wheel hub, in front of a flange portion of a second shield; the L-shaped fold defines, with a wing thereof, a tubular element arranged straddling wheel hub and an outer ring of the constant velocity joint, which has a free end supporting an annular seal; an annular signal generating insert completely covers a face of the flange portion where it is provided with a shallow recess defining, together with the L-shaped fold, a thrust shoulder for mounting the first shield.

Abstract: A hub bearing assembly (10) is provided with a stationary outer ring (20), an inner ring (30) with a flange (32) for mounting of a wheel, the flange (32) forming an annular relief (36) that protrudes in an axially inner direction and has an inner cylindrical surface (37); a sealing device (50), mounted on the outer ring (20), has a non-contacting axial lip (61) which extends towards the flange (32) and has a free end portion (62) which provides a labyrinth seal with the cylindrical surface (37) of the annular relief (36).
