Sealing ring and use thereof

A sealing ring, comprising:

• a first axial leg;
• and
• a sealing leg with a sealing lip,
• wherein, when viewed in cross section such that a radially outward direction extends from bottom to top, the sealing ring is in a shape of a seven,
• wherein the sealing leg is connected to a first end face of the first axial leg by a first joint,
• wherein the sealing leg has, on a side facing axially toward the first end face, a dirt lip with at least one sealing edge and a radially internal first boundary surface and a radially external second boundary surface,
• wherein the sealing leg and the dirt lip in a production-related state of the sealing ring delimit a substantially right angle radially internally and radially externally,
• wherein, in a production-related state of the sealing ring in each case, the sealing lip has a first diameter and the sealing edge has a second diameter, the first diameter being smaller than the second diameter,
• wherein the radially internal first boundary surface delimiting a right angle radially inside the dirt lip has a first length,
• wherein a third boundary surface of the sealing leg has a third length deviating from the first length, and
• wherein the first length is greater than the third length.
