Sealed rolling elements bearing comprising: - an inner bearing ring comprising at least one inner raceway (3a, 3b), said inner bearing ring having axial end portions (2a; 2b); - an outer bearing ring comprising at least one outer raceway (6a, 6b), said outer bearing ring having axial end portions (5a; 5b); - a plurality of rolling elements interposed between a pair of inner and outer raceways; - an axial sealing assembly stationary fixed to an axial end portion of the inner bearing ring and extending toward the axial end portion of the outer bearing ring, said axial sealing assembly comprising: ∘ an inside facing the rolling elements and an opposite outside; ∘ an annular rigid carrier disc having an inner diameter face at an inner perimeter thereof; ∘ a resilient sealing member having a main body, mounted on said disc, and an integral conical sealing lip which extends from said main body towards said outer bearing ring as well as towards the outside of the sealing assembly, said sealing lip delimiting a grease chamber for retention of grease therein; wherein said sealing lip slidingly and sealingly engages a corresponding sealing surface of the end portion of said outer bearing ring, characterised in that, the outer bearing ring has an inwardly protruding rib axially outward of the corresponding sealing surface of the end portion of said outer bearing ring; wherein at its outer perimeter said annular rigid carrier disc is provided with a groove in which said resilient sealing member is mounted; wherein the sealing lip has a free end portion remote from the main body of the sealing member, and such that-when seen from the outside - said inwardly protruding rib of the outer bearing ring obscures the free end portion of the sealing lip from view; wherein the outer perimeter of the carrier disc has a stepped design, with a largest diameter section at the outside of the axial sealing assembly, opposite said inwardly protruding rib of the outer bearing ring, an intermediate diameter section which defines with said sealing member the grease chamber, and with a smallest diameter section at the inside of the axial sealing assembly, defining said groove in which the main body of the sealing member is mounted. - an inner bearing ring comprising at least one inner raceway (3a, 3b), said inner bearing ring having axial end portions (2a; 2b); - an outer bearing ring comprising at least one outer raceway (6a, 6b), said outer bearing ring having axial end portions (5a; 5b); - a plurality of rolling elements interposed between a pair of inner and outer raceways; - an axial sealing assembly stationary fixed to an axial end portion of the inner bearing ring and extending toward the axial end portion of the outer bearing ring, said axial sealing assembly comprising: ∘ an inside facing the rolling elements and an opposite outside; ∘ an annular rigid carrier disc having an inner diameter face at an inner perimeter thereof; ∘ a resilient sealing member having a main body, mounted on said disc, and an integral conical sealing lip which extends from said main body towards said outer bearing ring as well as towards the outside of the sealing assembly, said sealing lip delimiting a grease chamber for retention of grease therein; wherein said sealing lip slidingly and sealingly engages a corresponding sealing surface of the end portion of said outer bearing ring, characterised in that, ∘ an inside facing the rolling elements and an opposite outside; ∘ an annular rigid carrier disc having an inner diameter face at an inner perimeter thereof; ∘ a resilient sealing member having a main body, mounted on said disc, and an integral conical sealing lip which extends from said main body towards said outer bearing ring as well as towards the outside of the sealing assembly, said sealing lip delimiting a grease chamber for retention of grease therein;
