Abstract: The invention relates to a radial shaft seal for sealing a shaft (2), which is guided through a housing wall opening (3). The seal comprises at least one first membrane-like, annular sealing element (15) with a sealing lip (22) which can be positioned against the shaft (2) in a sealing manner; a metallic, annular supporting element (16), onto which the sealing element (15) is pulled; and a centring surface (19) formed at the outer circumference of the edge area (18). In order to increase the lifespan of the seal, said seal can be surrounded by an adapter part (6) made from undulating curved sheet metal, which can be inserted flush into the housing wall opening (3). The adapter part (6) has a central, cylindrical opening (8) which is provided with a shoulder (11) at the rear end thereof in the compression direction. The centring surface (19) of the supporting body (16) has an allowance for the cylindrical opening (8) of the adapter part (6), and is pushed into said opening in a press-fitting manner. A second membrane-like sealing element (17), which can be firmly pressed between the shoulder (11) and the supporting body (16), is arranged between the supporting body (16) and the shoulder (11) provided in the opening (8) of the adapter part (6).
