Abstract: A Sealing device for sealing off a bearing unit from oil contaminants is disclosed herein. The sealing device comprises an annular metallic screen integral to a stationary inner ring, an annular metallic support integral to a rotatable outer ring, and an elastomeric element mounted on the support and comprises a radial lip and an axial lip that cooperate in a sliding and contacting manner with the screen.

Abstract: A structural unit for assembly to a trunnion of a universal joint bearing providing a cup, a sealing ring, which is fixed to the cup, and a shield, which is connected to the cup in a state in which the structural unit is not assembled to the trunnion. The cup includes a bottom and the sealing ring provides at least one sealing lip that points in a direction with an axial component towards the bottom.

Abstract: Low-friction sealing assembly for a vehicle wheel-hub unit inserted inside an annular interspace defined between a flanged rotating element and a stationary element, coaxial with each other, of the wheel-hub unit to protect at least one ring of revolving bodies arranged between the stationary element and the rotating element, and having a first annular screen and a second annular screen during use integral with the rotating element and with the stationary element; and an annular seal having lips that extend axially and radially projecting from the first screen towards the second screen inside an annular chamber defined by the first and second screens; the sealing assembly being a multi-stage sealing assembly provided with a first inner collecting stage designed to collect and expel some of the contaminants.

Abstract: A sealing assembly insertable between a stationary outer ring and a rotating inner ring of a bearing or hub bearing unit, having a first C-shaped shield supported by the inner ring and a second L-shaped shield supported by the outer ring. The first shield has a first annular sealing element having a first annular lip that extends axially cantilevered from the flange portion of the second shield in a position facing a radially outer sleeve shaped portion of the first shield and a second annular lip, elastically deformable, arranged radially on the inside of the first lip and which cooperates in contact with a radially inner sleeve shaped portion of the first shield, which carries a second sealing element having a third annular lip, which extends axially cantilevered from the first shield and towards the second shield and which is radially interposed between the first and the second lip.

Abstract: A roller bearing seal includes an insert part and a polymer part connected to the insert part, and the insert part includes an annular-disc-shaped middle section having a radially inner deflection and a radially outer deflection, and a first ratio (L2/L1) of an axial length (L2) of the outer deflection to an axial length (L1) of the inner deflection is less than 0.65.
