A divided type antifriction bearing assembly with a seal having two semicircular divided inner annular members each having a track on the outer peripheral surface thereof and having at the axially outer end of the track a flange portion which is in contact with the end surface of a roller, the inner annular members each forming a cylindrical shape having a cylindrical portion axially extending continuously to the flange portion, the inner annular members being divided along the axis thereof and coupled together, an outer annular member having a track on the inner peripheral surface thereof opposed to the inner annular members, and rollers provided between the tracks of the inner and outer annular members is characterized in that the bearing assembly includes a seal member mounted radially inwardly outside the track of the outer annular member, the inner peripheral portion of the seal member is in sliding contact with a portion of the cylindrical portion of each of the inner annular members, and the inner annular members have, at the opposite ends thereof leaving the cylindrical portions, slits opposed to each other at symmetrical positions passing through the axis and are naturally divided with the slits as the boundary.
