Claims

[Claims for Utility Model Registration] A rotating shaft having an inner race surface formed on its outer periphery, an outer race disposed to face the inner race surface, and a rotating shaft interposed between the inner race surface and the outer race. In a unit bearing in which a rolling member is formed into a unit and assembled into a predetermined housing in the unitized state, a core ring assembled to an outer race of the unit bearing is in contact with an outer circumferential surface of the rotating shaft. an inner periphery seal portion that maintains an oil-tight connection between the core ring and the rotating shaft; and an outer periphery that maintains an oil-tight connection between the outer race and the housing when the unit bearing is assembled to the housing. Oil seal for unit bearings with a seal part.
