ル軸受装置。The spindle that drives the rotating body and the housing that holds the multiple bearings that rotatably support the spindle are made of materials that have the same coefficient of linear expansion, and flanges are formed on the outer end surfaces of the outer rings of the multiple ball bearings. A boss having flanges that abut against the upper and lower surfaces of the housing, a step provided on the outer periphery of the spindle abuts an inner ring of one of the ball bearings, and a step that abuts the inner ring of another ball bearing. from the free end of the spindle, and the free end of the spindle and the boss,
After applying an appropriate preload between the inner rings of the plurality of ball bearings by applying a force in the axial direction of the spindle between them, the outer rings of the plurality of ball bearings are attached to the housing, and the inner rings are attached to the spindle, respectively. A spindle bearing device characterized in that it is configured in a fixed manner.
