Abstract

See full text

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.
