Abstract A rolling bearing provided with a sealing device according to the present invention includes a ring-shaped outer ring having an outer ring trajectory, a ring-shaped inner ring positioned radially inward of the outer ring and having an inner ring trajectory, a plurality of rolling bodies circumferentially spaced apart between the inner ring trajectory and the outer ring trajectory, a retainer provided between the inner ring and the outer ring, having a plurality of pockets circumferentially spaced apart in which the rolling body is positioned, and maintaining the circumferential gap of the rolling body, and a sealing device provided in an opening formed between the outer ring and the inner ring. An outer ring sealing device groove that is concave and extends along the circumferential direction is formed in the widthwise surface of the outer ring. The sealing device includes an annular sealing device main body and a radially inward sealing device coupling portion provided at the radially outer end of the sealing device main body. The sealing device is pushed inward in the axial direction, and then the sealing device coupling portion is inserted into the outer ring sealing device groove to be coupled to the outer ring. 본 발명에 따르는 씰링기구를 구비한 구름베어링은 외륜 궤도가 형성된 링 형태의 외륜과, 상기 외륜의 반경 방향 내측에 위치하며 내륜 궤도가 형성된 링 형태의 내륜과, 상기 외륜 궤도와 내륜 궤도 사이에서 원주 방향으로 이격되어 복수로 구비되는 전동체와, 상기 내륜과 외륜 사이에 구비되며 원주 방향을 따라 이격된 복수의 포켓이 형성되어 각 포켓에 전동체가 위치하여 전동체의 원주 방향 간격을 유지시키는 작용을 하는 리테이너와, 상기 외륜과 내륜 사이에 형성된 개구부에 구비되는 씰링기구로 이루어지며; 상기 외륜의 폭면에는 오목하며 원주 방향을 따라 연장된 외륜씰링기구홈이 형성되고, 상기 씰링기구는 환형의 씰링기구본체와 상기 씰링기구본체의 반경 방향 외측 단부에 구비되며 축 방향 내향하는 씰링기구결합부로 이루어지며; 상기 씰링기구가 축 방향 내향 가압되어 상기 씰링기구결합부가 외륜씰링기구홈에 삽입되어 외륜에 결합되는 것을 특징으로 하는 씰링기구를 구비한 구름베어링에 관한 것이다.
