Sealing system and sealing ring

A sealing system for sealing shafts against liquid media, comprising:

• at least one sealing ring and supporting rings surrounding the shaft, which supporting rings form a clamping space for clamping the sealing ring, which clamping space is open radially inside, by way of an annular gap, relative to a system center axis between the supporting rings, for feeding the sealing ring through,
• wherein the sealing ring comprises:
• a radially outer clamping section for accommodating, in the clamping space, a radially inner sealing lip for directly or indirectly resting against the shaft, and
• a connecting web for connecting the sealing lip to the clamping section,
• wherein opposing corner regions, located radially inside, of the clamping space are formed by inclined run-on surfaces that diverge when viewed from the annular gap radially towards the outside,
• wherein the radially outer clamping section comprises two opposite edge regions that are formed by inclined surfaces that correspond to the run-on surfaces,
• wherein the annular gap comprises two opposite inclined gap surfaces diverging radially towards the outside, and
• wherein each of the run-on surfaces is separated from a respective one of the gap surfaces by a respective bottom surface which are aligned parallel to a system center axis and spaced apart from each other by way of the annular gap.
