Abstract: A sealing device for sealing a bearing unit between a stationary radially outer ring and a rotary inner flanged ring against external contaminants. The sealing device includes a rotary metal first shield which has a shaped annular form and is mounted on the flanged ring, a stationary metal second shield which has a shaped annular form and is mounted on the radially outer ring and an elastomer annular sealing element, which is wholly supported by the second shield, the sealing element having an annular contacting lip and a non-contacting lip arranged radially outside the contacting lip. The non-contacting lip has a curved cross-section defined by different radii of curvature and a radially outward-facing concavity.

Abstract: A transmission assembly for vehicles, including a rolling bearing having a sealing device composed of a first annular screen coupled with a stationary outer ring of the bearing and a second annular screen coupled with a rotating inner ring of the bearing. Radially outer first and second L-shaped portions of the first and second screens project axially from the bearing and towards a constant velocity joint, the first L-shaped portion having a first and a second annular lip which form with the second L-shaped portion a radial sequence of labyrinth seals. A third annular sealing lip may be arranged radially downstream of the sequence of labyrinth seals and cooperates in sliding contact with the second screen. An encoder may be mounted on the second L-shaped portion and may have an annular overhang which forms with the first lip a first labyrinth seal.

Abstract: A sealing unit for a stem of a mono-tube shock absorber includes a first seal having a sealing ring providing an annular sealing lip that projects in a radially and axially inner direction to slidingly cooperate with the stem and ensure a sealing action with respect to pressurized working fluid inside the mono-tube shock absorber; a second seal with a sealing ring having an annular sealing lip, which projects protruding in a radially and axially external direction to slidingly cooperate, with the stem and ensure a sealing action with respect to the outside of the mono-tube shock absorber; a reinforcing ring snapped into an annular seat of the sealing ring. The reinforcing ring is arranged axially locked between the lip and a bottom wall of the second sealing lip; the first and second seals are two physically distinct and separate elements assembled separately inside a body of the shock absorber.

Abstract: In a wheel hub unit a sealing assembly inserted between a stationary outer ring and a rotating inner ring of a rolling bearing includes a first screen coupled with the outer ring, an elastomeric annular element attached to the first screen, and a second screen faces the first screen and coupled with the inner ring, the second screen having a flange portion with a radially outer edge facing a sleeve portion of the first screen, the first screen having a non-contacting annular lip with a free end substantially flush in a radial direction with the radially outer annular edge, the free end cooperating with the radially outer edge to form a labyrinth seal.
