ABSTRACT:
A bearing sealing device comprises a middle ring having peripheral channel adapted to partially accommodate an annular sealing means that exerts a sealing action against a rotating member to be protected, and against the inner surface of the encircling casing within which the rotating member is located, and an lower ring which, by being urged against the middle ring, insures a sound tightness by virtue of the contact of one annular surface thereof with an opposing surface of the first annular element; a spacer means insertable into the first annular element, which spacer is retained in place by the lower ring. It is provided with a lower cylindrical recess partially accommodating a second annular seal which is adapted to exert a sealing action on the central shaft on which the rotating member being protected is mounted.
