The invention relates to a rotor bearing system (). Said system comprises a housing () in which a first permanent magnet () is mounted such that it can rotate about a first axis (). A rotor () for conveying a liquid comprises a second hollow-cylindrical permanent magnet (), which is mounted such that it can rotate about a second axis. The first permanent magnet () and the second permanent magnet () overlap axially at least partially, wherein the first permanent magnet () is disposed offset relative to the second permanent magnet (). In the axial overlap region () of the first permanent magnet () and the second permanent magnet (), the housing () is positioned between the two permanent magnets (). A first bearing () is configured for the relative axial positioning of the rotor () and the housing () with respect to one another and for receiving an axial force resulting from the arrangement of the first permanent magnet () and the second permanent magnet (), and a second bearing () and a third bearing () are configured for receiving radial forces and for positioning the axis of rotation of the second permanent magnet ().

The invention relates to a magnetic coupling element () with a magnetic bearing function. The magnetic coupling element () has a drive-side coupling magnet () arranged on a drive shaft (), and also an output-side coupling magnet () arranged on an output shaft (), the output-side coupling magnet () being magnetically coupled to the drive-side coupling magnet (), and finally a bearing magnet ring () which is non-rotatably mounted with respect to the drive-side or output-side coupling magnet () or (), a bearing magnet portion () of the bearing magnet ring () having the same polarity as a coupling magnet portion () opposite the bearing magnet portion ().
