PROBLEM TO BE SOLVED: To downsize in an axial direction, a sealed rolling bearing of a double seal structure using an inner ring as a rotation side race.SOLUTION: A sealed rolling bearing is downsized in an axial direction by fitting both of an inner seal 5 and an outer seal 6 which constitute a double seal to an inner ring 1 of a rotation side race and to prevent two seals 5, 6 from rotating relatively to eliminate the possibility that both seals 5 and 6 come into contact with each other even when the inner ring 1 moves or inclines in an axial direction and further by allowing a clearance between both seals 5, 6 to be set small. By using the inner seal 5 and the outer seal 6 as a contact seal and a non-contact seal respectively, the bearing is structured to suppress an increase of a torque required for rotation of the inner ring 1. |
