A sealing assembly for bearings, in particular for use in agriculture, comprising a primary sealing barrier and a secondary sealing barrier, which are arranged in series along a potential path (P) of ingress of contaminants into the bearing, and have, respectively, a first seal and a second seal with a plurality of contact lips. The contact lips of the first and second seal with a plurality of contact lips may be static lips that do not rotate about an axis (A) of rotation of the bearing.

Sealing assembly for bearings, in particular for use in agriculture

Sealing device including a first annular element coupled to a first fixed mechanical member, and a second annular element coupled to a second rotating mechanical member, for protecting an annular compartment delimited between the members, the first element being provided with at least one annular sealing lip configured to interact with the second element, which has a radial edge of a flange portion arranged at an edge of a sleeve portion of the first element, thus forming with the latter a radial gap configured as a labyrinth seal; wherein the radial gap of the flange portion of the second annular element carries a plurality of depressions arranged in a crown, spaced adjacently to one another at the radial gap and configured to generate, as a result of the rotation of the second element, a dynamic effect (F) for the purpose of repelling any contaminants impelled towards said radial gap.
