A device has two components that delimit a space containing oil. A rotationally fixed component is moved axially to press against an axial sealing surface of a rotatable component by an actuating force to seal the space in a region of another axial sealing surface. An air flow between the two sealing surfaces results in a further actuating force, acting on the fixed component in the axial direction to counteract the actuating force and move the fixed component away from the rotatable component once a defined speed of rotation of the rotatable component is reached. The rotatable component and the fixed component are supplied with oil close to the sealing surfaces. In the installed position of the fixed component, oil is passed from an upper region of the fixed component in the circumferential direction of the fixed component in the direction of a lower region of the fixed component.
