An annular sealing assembly for a bearing means (2,3) between a stationary member (1) and a member (4) rotatably supported thereon comprises at least two first and at least two second annular sealing means (11, 12), each with an annular projecting seal means (13,14), which are dimensioned and arranged on the rotary and stationary members (1,4) with their projecting seal means (13,14) interleaved, to define a narrow zig-zag passage, to prevent the ingress of foreign material to the bearing means (2). |
