PROBLEM TO BE SOLVED: To provide an application system for a superconductive magnetic bearing as a superconductive magnetic bearing system for damping and stably supporting the vibration of a lateral/vertical-axis rotor in no contact by optimally combining a whole rotating machine system using the superconductive magnetic bearing as a structural element and designing the arrangement. SOLUTION: In the outer rotor radial type superconductive magnetic bearing 3, the magnetizing direction of a permanent magnet aggregate 6 constituting a cylindrical permanent magnet rotating shaft 2 is set to be the radial direction of the rotating shaft perpendicular to the axial direction of the rotating shaft so that ring permanent magnetic bodies whose magnetizing directions are unified to be outward positive, e.g., exit on the same circle in viewing the outer peripheral direction from a rotational center line. In a system of building up the ring permanent magnetic bodies in layers in the axial direction of the rotating shaft, the superconductive magnetic bearing has high loading force/high rigidity property in the radial direction of the rotating shaft than in the axial direction of the rotating shaft. In a system of building up the ring permanent magnet bodies while alternately changing their magnetizing directions to be positive or negative in layers, it has high loading force/high rigidity property in the axial direction of the rotating shaft.
