FIELD: rolling production. SUBSTANCE: sealing device has cover 5 and radial sealing member positioned between bushing-journal 1 and cover 5. Sealing member consists of two parts 7 and 8. They are of identical geometrical sizes and are made of similar material. In this case, internal surface of cover 5 which contacts parts 7 and 8 of radial sealing member is made in the form of two steps "a" and "b" of different diameter. Diameters of steps are selected to provide for maximum pressing force for each of parts 7 and 8 of radial sealing member intended for sealing of working facilities of different kinematic viscosity. EFFECT: higher reliability and durability. 1 cl, 1 dwg
