Abstract: A bearing sealing device includes two seals (inner and outer seals) sealing the space between the inner and outer races of a bearing to ensure higher seal performance, and also to reduce the area of the inner periphery of the outer race that needs to be ground. The bearing sealing device includes a ring constituted by a metal annulus, and a rubber part. The metal annulus is formed by cold pressing, and has a seal contact surface kept in contact with seal lips of the outer seal. The rubber part includes a press-fitted portion fixed to the inner periphery of the outer race. The inner race has, on its outer periphery, a cylindrical fitting surface to which the outer seal is press-fitted.

Abstract: A fixing arrangement for a rubber seal for sealing a rolling bearing is proposed which can be easily mounted in position by press-fitting and which prevents rotation of the rubber seal together with the rotary member of the bearing. A thick-walled fitting portion 3 and a protrusion 4 are formed on the radially outer portion of a rubber seal 1 reinforced by a metal core 2. The fitting portion 3 is press-fitted in a seal groove 22 formed in the radially inner surface of an outer race 21 at each end. The protrusion 4 is brought into elastic contact with a large-diameter cylindrical surface 23 formed on the outer race 21. Thus, the rubber seal 1 is fixed in position and prevented from rotating together with the inner race of the bearing.

Abstract: A bearing seal includes a metal core having a radially outer portion engaged in an inner seal groove of a bearing outer race. The core includes a bent portion engaged in the seal groove, a radially outer flange extending inwardly from an end of the bent portion located inside the bearing, a tapered tubular portion having a large-diameter end thereof connected to a small-diameter end of the outer flange and a small-diameter end thereof located axially outwardly of its large-diameter end, and a radially inner flange extending inwardly from the small-diameter end of the tubular portion. A rubber seal is fixed to an inner surface of the metal core that faces the interior of the bearing. The rubber seal includes a thick-walled portion having an inner radial step, and formed with three lips that elastically contact the inner race outer surface. The thick-walled portion includes a small-diameter thick-walled portion.

Abstract: The bearing seal includes a metal core 1 having a radially outer portion engaged in a seal groove 41 formed in a radially inner surface of an outer race 40 of a bearing at its end portion. The metal core 7 includes a bent portion 2 engaged in the seal groove 41, a radially outer flange 3 extending radially inwardly from an end of the bent portion 2 located inside of the bearing, a tapered tubular portion 4 having a large-diameter end thereof connected to a small-diameter end of the radially outer flange 3 and a small-diameter end thereof located axially outwardly of its large-diameter end, and a radially inner flange 5 extending radially inwardly from the small-diameter end of the tapered tubular portion 4. A rubber seal 11 is fixed to an inner surface of the metal core 1 that faces the interior of the bearing.
