in the present case recess 5 is introduced into bearing ring 1 as a recess with the aid of a recess turning process to position a sealing element lateral surface 3 of recess 5 is provided with a corresponding contour 7 for this purpose contour 7 includes a contact section 9 for axially securing an inserted sealing element a control point 10 on contact section 9 as well as an axial contact surface 11 which prevents the sealing element from tilting in the relaxed state the retaining lip of a theoretically inserted sealing element extends radially beyond control point 10 of contact section 9 by a distance c contact section 9 of contour 7 is inclined in the radial direction against the direction of installation and merges directly with a radial clearance 13 due to the incline of contact section 9 it is ensured that an inserted sealing element may be positioned axially on contact section 9 or on lateral surface 3 of recess 5 in a form locked manner radial clearance 13 in turn prevents a massive contact between the sealing element and contour 7 of recess 5 in this way a gap is maintained between the sealing element or the elastomer section of the sealing element and contour 7 which compensates for tolerances for example roundness errors of both recess 5 and the sealing element axial contact surface 11 on the other hand enables a sealing element to planarly abut with its axial contact surface in the installed state thereof so that a tilting of the sealing.
