Abstract
An angular ball bearing for a turbocharger, including 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, the 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.
