Sealing assembly particularly for railway axle bearings

A sealing assembly which can be interposed between two relatively rotatable members substantially to seal an annular cavity defined between the said members in a fluid-tight manner, particularly for railway axle bearings, of the type comprising a rigid baffle which can be fitted securely to the radially outermost member and a sealing element rigidly carried by and projecting from the said rigid baffle and able to cooperate with the radially inner member or with an element to which the said radially inner member is connected, characterised by the fact that the said rigid baffle includes a fixing portion which can be fixed rigidly to the said radially outer member, and a sleeve portion coaxial with the said fixing portion and projecting with respect thereto, the said sleeve portion being firmly fixed at its free end to the said sealing element and to a cup-shape cover fixed in a removable manner to an edge of the said free end, the said cover substantially closing the free end of the said sleeve portion of the baffle in a fluid-tight manner and, with it, the said annular cavity, and the said sealing element being provided with a plurality of radial non-sliding ribs which can cooperate with the radially inner member and with the said element fixed to it to define a labyrinth seal.
