ABSTRACT:
A sealing ring (12) has an annular principal body (15) responsible for its dimensional stability, such body having an annular groove on at least one axial side, in which groove a sealing body (16), consisting of rubber-elastic material, is held. The sealing body (16) has a sealing bead (24) projecting axially past the principal body (15). The capacity of the annular groove (25) is at least equal to the volume of the sealing body (16) so that the annular groove (25) is in a position of receiving the material of the sealing body (16) defining its sealing bead (24) during action on and deformation of the sealing bead (24).
