A bearing seat provided in or on a cylindrical surface of a component to which the bearing is to be mounted is constructed so that the component at which the bearing seat is provided is softer at least in the surface region than the ring(s) of the bearing that is to be interconnected to the component via the bearing seat. In addition, either one of the bearing seat and the bearing ring in their surfaces facing each other has a number of surface irregularities arranged ring to cause deformation to the softer surface region under a mutual axial mounting motion between the bearing seat and the bearing ring to thereby form a mutual grip between the seat and the bearing ring.
