1. A sealing ring of a sealing sleeve for a stator of an electrical machine, the sealing sleeve having a multiplicity of coils and stator teeth, the sealing ring comprising:
a first, hard component; and
a second, deformable component,
wherein the second component is applied to a first axial surface of the first component,
wherein the second component comprises first seal sections arranged on the first axial surface in a manner distributed along a tangential direction and with specific angular spacings relative to one another,
wherein the angular spacings between centers of two adjacent first seal sections when viewed in the tangential direction are 360°/n212′,
wherein n212′ indicates a number of first seal sections, and
wherein n212′=n121/N, where n121 indicates a number of coils of the stator and N≥2.
