According to the present invention, a low-torque seal assembly for a bearing comprises an elastic body and a slinger. The elastic body includes a protrusion, and the slinger includes an outer diameter part. In addition, the protrusion and the outer diameter part are formed to have a shape in which the low-torque seal assembly is not separated after assembly. The elastic body has a mud-collecting longitudinal rib and a mud-collecting axial rib to reduce the introduction of foreign substances into a seal and minimize the contact pressure of a contact part against the slinger. Thus, a drag torque-reduced bearing can be designed and manufactured. As parts with a seal are not separated before being assembled in the bearing, the introduction of foreign substances into an assembly part can be prevented, and the parts can be easily assembled when mounted on the bearing. When the bearing is mounted on a vehicle wheel and the wheel rotates, the protrusion formed on an end of a reinforcing steel cylinder part limits the introduction of foreign substances, including water, into the bearing so that the lifespan of the bearing is extended. Performance can be improved by minimizing sealing drag torque.

    본 발명은 탄성체와 슬링거의 구성을 포함하며 탄성부는 돌기를, 슬링거는 슬링거외경부를 포함한다. 또한, 돌기 및 슬링거외경부를 형성하여 조립 후 분리가 되지 않는 형상으로 하고, 탄성체에 머드포집 경방형립과 머드포집 축방향립을 형성하여 이물질의 시일 내 유입을 저감하고, 슬링거에 대한 접촉부 접촉 압력을 최소화하는 것으로서 드래그 토크 저감 베어링 설계 제작이 가능하다. 시일을 구비한 부품이 베어링에 조립 전 분리되지 않으므로 조립부내 이물 유입을 방지할 수 있으며, 베어링 장착 시 조립이 용이하며, 베어링이 자동차 휠에 장착되어 휠이 회전할 때 보강철원통부 단부에 형성된 돌기로 인하여 물을 포함한 이물질들이 베어링 내부로 유입되는 것이 제한되어 베어링수명이 연장되며, 실링 드래그 토크를 최소화하여 성능이 향상되는 효과가 있다.
