Abstract

A seal includes: a seal ring, having at least one dynamically stressed seal lip; a supporting ring made of a toughened material; and a connecting device made of an elastomeric material. The seal ring and the supporting ring are connected to one another. The supporting ring includes a radial leg, to which, in a radial direction, the seal lip is fixed. The radial leg is formed of two parts and, in the radial direction, has arranged a first partial leg and, in an other radial direction has arranged a second partial leg. The partial legs are associated adjacent with a first radial distance and delineate a first gap. The first partial leg is connected with the seal lip. The first and the second partial legs are fixed to one another by the connecting device. The connecting device, when viewed in cross section, has an axial length and a radial height.
