A device for sealing a rotating shaft that penetrates a stationary housing wall has a sealing ring fastened to the housing wall and arranged between the housing wall and a shaft. The sealing ring has sealing oil supply bores supplying sealing oil into a sealing gap formed between an inner wall surface of the sealing ring and an outer wall surface of the shaft. The inner wall surface has pocket-shaped recesses where the sealing oil supply bores open. The pocket-shaped recesses extend in the circumferential direction of the sealing ring. The inner wall of the sealing ring has at least one circumferential boundary stay that delimits and seals the pocket-shaped recesses in an axial direction of the sealing ring toward the first or second housing side. The inner wall surface of the sealing ring has a circumferential groove that connects the pocket-shaped recesses to one another.
