Abstract
A bearing assembly includes a rolling bearing having a bearing ring fitted to a mating member, i.e., a shaft or a housing, with a clearance fit. Of the bearing ring and the mating member, the bearing ring has a flank face that separates a fitting surface of the bearing ring across the entire width thereof. The flank face defines a radial gap between the bearing ring and the housing. In a load receiving region where the radial gap remains, a portion of the bearing ring which is deformed in a wave-shaped pattern is kept out of contact with the fitting surface of the housing. The wave-shaped deformation of the bearing ring does not act as traveling waves that cause creep of the bearing ring.
