  • Publication number: 20190285182
    Abstract: A seal ring in the form of a grooved ring for sealing a movable machine element toward a stationary housing includes: a radially inner axial leg with a dynamic sealing edge; a radially outer axial leg with a static sealing edge; and a radial leg connecting the two axial legs. The seal ring is produced from a thermoplastic material. A recess is formed between the two axial legs and the radial leg. The radially inner axial leg has, on a surface of the radially inner axial leg on a machine element side, a rounded transition to a surface of the radial leg that faces away from a pressure.
