A magnetic suspension bearing, comprising a rotating shaft (1) and a thrust disc (2) arranged on a first end of the rotating shaft (1). Axial bearings (3) are respectively provided on both ends of the thrust disc (2). The thrust disc (2) is sleeved outside the rotating shaft (1). A shaft shoulder (4) is disposed on the rotating shaft (1). A locking nut (5) is arranged on an axial outer side of the thrust disc (2). The locking nut (5) can axially compress the thrust disc (2) onto the shaft shoulder (4), and is provided with a locking hole (6). The locking hole (6) is internally provided with a locking structure capable of locking the locking nut (5) onto the rotating shaft (1), thereby ensuring that the thrust disc (2) is effectively locked, preventing the thrust disc (2) from loosening, and improving the stability of the thrust disc (2). The present invention also relates to a compressor and an air conditioner. Palier de suspension magnétique comprenant un arbre rotatif (1) et un disque de poussée (2) agencé
