摘要： A sealing unit having a first annular rotating shield and a second annular shield is provided. The second annular shield is fixed and arranged in front of the first shield for delimiting therebetween a first annular chamber and a sealing ring provided with at least a first and a second annular lips, which extend axially and radially projecting from a flange portion of the second shield and towards a flange portion of the first shield, inside the annular chamber. The first shield integrally supports a third annular lip that extends projecting from the first shield towards one of the first and second lips without touching it for defining a second dynamic labyrinth seal between the first and second shield and inside the annular chamber.

摘要： 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.
