IN THE MAJORITY OF DESIGNS IN COMMON USE, THIS IS ACHIEVED THROUGH THE FACT THAT AT LEAST ONE OF THE TWO CARBON SEALING RINGS IN A FEEDER HEAD SEAL HAS A CONVEX OR CONCAVE SEALING FACE. THE FEEDER HEAD SEALS ARE OFTEN ALSO EQUIPPED WITH CARBON BEARINGS, WHICH ARE OFTEN RUN DRY. IN STEAM HEADER SEALS, ONE OF THE TWO SEALING RINGS CAN SERVE AS A BEARING AT THE SAME TIME.
