    摘要： A sealing assembly for bearings, in particular for use in agriculture, the sealing assembly having a first shield, which extends from an outer surface of the inner ring to an inner surface of the outer ring, and is mounted on the outer surface of the inner ring, and a seal with a plurality of contact lips supported by the first shield, and provided with a predetermined number (N) of contact lips arranged in series axially next to one another. The contact lips may lie, when in a respective pre-assembly configuration, in respective planes (P) inclined with respect to a central axis (A) of the bearing, and may have radial lengths decreasing axially towards the bearing.

    摘要： A sealing device for a bearing unit is provided. The sealing device includes a dynamic component, a static component having a shaped metallic support, and a plurality of sealing lips not making contact with the dynamic component and two lips making contact with the dynamic component. A second sealing lip of the non-contacting sealing lips and the dynamic component define a labyrinth seal, and a fixed spoiler arranged along the labyrinth seal for the creation of turbulent motion inside the labyrinth seal to provide a complete sealing action preventing any entry of components inside the bearing unit.
