To provide a device for defying such a conventional idea that a bearing device is constructed to compensate for potentially-generated most strong axial force which derives from the operation of equipment.
A shaft bearing has an inside ring and an outside ring, and is arranged in a bearing housing. The inside ring is firmly joined to a shaft, and a rotating body extends between the inside ring and the outside ring. An axial support is provided in outside-ring shape with a spring unit. The spring unit operates in the axial direction of the shaft, and is supported with the first end of the outside ring of the shaft bearing. The second end of the spring unit is guided into an isolated bearing part. The spring unit which is embodied so that, when axial force greater than a design value occurs, the outside ring of the shaft bearing is moved in the axial direction, and when it exceeds predetermined maximum force, the rotating speed of the shaft is reduced or the drive of the shaft is completely stopped, actualizes partial compensation.
