Abstract

1. A radial shaft sealing ring comprising a reinforcing ring (1), a sealing ring (2) of resilient material which is fixed on the reinforcing ring and projects in the axial direction, an inward-pointing circumferential sealing edge (3) in the projecting region of the sealing ring and an outwardly open groove radially outside the sealing edge in the sealing ring, an annular helical spring being arranged in the groove for the purpose of pressing the sealing edge (3) resiliently against the surface of the shaft sealed off, the groove being bounded on both sides in the axial direction by annular beads projecting radially outwards and the annular beads being pierced by a plurality of auxiliary grooves distributed uniformly in the circumferential direction and extending in the axial direction, characterized in that, at the points of mutual intersection, the auxiliary grooves (5) and the groove have an essentially corresponding depth and in that the auxiliary grooves (5) have a groove base (6) which, in the direction of the reinforcing ring (1), extends parallel to the inner side (7) of the lip ring (2).
