1. A part, comprising:
a rotationally symmetric region;
a machining surface finished in a planar manner, a normal direction of the machining surface being oriented parallel to an axis of rotational symmetry of the rotationally symmetric region; and
an annular recess that extends entirely around the part in a circumferential direction and arranged in an axial location of the part that coincides with an axial location of the machining surface;
wherein, in a circumferential angular region not covered by the machining surface, the annular recess is axially symmetric and arranged as a groove, and, in a circumferential angular region covered by the machining surface, the annular recess is axially asymmetric and arranged as one axial half of the groove.
