ABSTRACT:
In this seal-carrying bearing, seals are fitted removably in outer races. Owing to a resilient force occurring due to the elastic deformation of the seals fitted in annular grooves formed in the outer races, the seals are held in the annular grooves. Each of the seals comprises a core member fitted in the relative annular groove and formed by an elastic metal plate, and an elastic seal member fixed unitarily to the core member. The elastic seal member comprises a support portion fitted in the annular groove and held therein by a resilient force owing to elastic deformation occurring to the insertion thereof into the annular groove, a seal base portion closely contacting a circumferential surface of the relative outer race along the annular groove, and a seal lip portion extending from the seal base portion to a position in which the seal lip portion contacts the counter surface of the inner race.
