Abstract

An arrangement includes a radial shaft seal (2) that surrounds a shaft (1), wherein an elastomer body (4) forms a sealing lip (5) for bearing against the shaft (1), wherein the sealing lip (5) has a sinusoidally curved sealing edge (6) on its side which faces the shaft (1), which sealing edge runs around along the inner circumference of the sealing lip (5), and wherein the sealing edge (6) bears against the circumferential face (7) of the shaft (1). The radial shaft seal as a single component is able to produce high dynamic seal tightness in a plurality of different applications.
