Abstract
A shaft sealing ring for sealing off a media side from an outer side of a shaft arrangement is disclosed. A sealing portion, in the operating state, extends along a sealing axis, and has a running surface for dynamic sealing contact with a sealing surface of a machine part of the shaft arrangement. The sealing portion is provided with a plurality of profile grooves, which are each laterally delimited by a first lateral flank, which is arranged on the media side during operational use of the shaft sealing ring. A second lateral flank is arranged on the ambient side during operational use. The profile grooves have a flow cross section with maxima and minima for a lubricating medium. Each minimum of the flow cross section of a profile groove is arranged substantially in alignment with a maximum of the flow cross section of the respectively closest profile groove.
