Abstract

A bearing assembly includes a hub element or housing element which has an accommodating bore for at least one rolling-element bearing, the rolling-element bearing being disposed with its outer ring in a press-fit arrangement in the accommodating bore, and the outer ring having at least one first axial region along at least one raceway of the outer ring and at least one second axial region extending outside the raceway. To ensure a proper fit of the bearing ring in the hub or housing element over a wide range of operating temperatures, the receiving bore and the outer circumference of the outer ring are configured such that at the ambient temperature the radial clamping force between accommodating bore and outer ring in the first region is smaller than in the second region.
