The inner and outer rings are separably connected and located at the outer ring end, and the inner and outer rings are arranged such that the parallel sequence of flanges from the bearing inward to the outside begins with the outward facing flange and ends with the outward facing flange. , At least one of the inner ring body and the outer ring body is made of a lubricating nonmetallic material on the peripheral surface side having a flange, and the ring body closest to the inside of the bearing among the plurality of outer ring bodies is detachably attached to the outer ring end. The depth of the spigot joint between the outer ring body and the end of the outer ring is determined by the axial clearance formed by the inward flange of each outer ring body and the outward flange of each inner ring body. A bearing sealing device characterized by having a depth that prevents the body from coming off the outer ring. (2) The sealing device for a bearing according to claim (1), wherein the inner ring closest to the inner side of the bearing is shrink-fitted and fixed to the inner ring extension ring. (3) The gap formed between the inner ring body and the outer ring body is defined by the fact that the bearing inner opening and the bearing outer opening are inclined toward the outer diameter side .
The bearing sealing device described in paragraph (1) . (4) Sealing of the bearing according to claim (1), in which the outermost flange of each flange of the inner ring body and the outer ring body has a plate thickness larger than that of the other flanges.
