Abstract

The invention relates to a magnetic coupling element (100) with a magnetic bearing function. The magnetic coupling element (100) has a drive-side coupling magnet (109) arranged on a drive shaft (106), and also an output-side coupling magnet (115) arranged on an output shaft (112), the output-side coupling magnet (115) being magnetically coupled to the drive-side coupling magnet (109), and finally a bearing magnet ring (118) which is non-rotatably mounted with respect to the drive-side or output-side coupling magnet (109) or (115), a bearing magnet portion (133, 136) of the bearing magnet ring (118) having the same polarity as a coupling magnet portion (127, 130) opposite the bearing magnet portion (136).
