Abstract
A method is provided for supporting rotatable devices, particularly a medical scanner having an inner ring and an outer ring. According to the invention, the inner ring and outer ring are guided without contact in the axial and/or radial direction by the magnetic field of electromagnets, and the distance between them is monitored and controlled by means of distance sensors. For a bearing implementing said method according to the invention, the outer ring is made in multiple parts and has a U-shaped cross section that is open to the inside in the assembled state, into which the inner ring () extends, and electromagnets and distance sensors are disposed in the axially and radially opposite areas of the inner ring or outer ring.
