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.

Low-friction sealing assembly for a wheel-hub unit and wheel-hub unit equipped with such a sealing assembly

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.

Sealing assembly for rolling bearings, in particular for a hub bearing unit of vehicles and associated hub bearing unit

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 (L/L) of an axial length (L) of the outer deflection to an axial length (L) of the inner deflection is less than 0.65.
