The invention relates to an angular ball bearing for a turbocharger, comprising an outer ring and a cage, along the circumference of which rolling element pockets are arranged and at the end face of which a cage guide surface runs, said cage guide surface together with a surface on the inner circumference of the outer ring forming a sliding surface pair. The sliding surface pair forms a transition region at the sliding surface pair end facing the rolling element pockets such that - when the cage and the outer ring are positioned in an axially parallel manner, the spacing between the surfaces which form the sliding surface pair increases in a monotonous manner, said increase growing continuously. The progression of the spacing achieves a reduction of the wear susceptibility. |
