At least one rubber laminated bearing-seal, consisting of multiple flat or curved alternate laminations of metal and rubber bonded together and having an aperture, is seated in a complementally-configured apertured receptacle in the wall of a pressure vessel and supports and seals a shaft that penetrates said apertures and extends through the wall. Shear strains in the rubber laminations permit the shaft to carry limited movements through the wall while the laminations seal against any flow of the liquid or gaseous medium on one side toward the other and withstand the resulting thrust caused by large pressure differences. The torque reaction of this bearing-seal is essentially proportional to rotation angle. A potential use is in the intense undersea hydrostatic pressure environment at great depths, carrying limited motion through the hull of a submersible craft. Safety backup against seal failure is provided.
