A radial shaft seal has an elastomeric sealing lip with an inner side facing a shaft to be sealed. The sealing lip has a first circumferential ring arranged at the inner side and resting against the shaft to seal a medium side from an air side. Return conveying elements are arranged circumferentially about the sealing lip at the inner side and at a side of the first circumferential ring facing the air side. They return leakage medium, independent of a rotational direction of the shaft, to the medium side. A second circumferential ring at the inner side is positioned at a side of the return conveying elements facing the air side. The first circumferential ring is an elevation with depressions, also formed as elevations, distributed circumferentially thereabout. The depressions extend toward the second circumferential ring and are positioned, respectively, between two of the return conveying elements neighboring each other.
