Abstract

A spindle assembly 10 has a flexibly mounted bearing 12 that is mounted with the inner race 14 clamped to the spindle shaft 16, and with the outer race 18 mounted concentrically within a thin metallic diaphragm 20. The outer circumference of the diaphragm 20 is fixed to the bearing housing 22. The bearing 12 is allowed to move in the axial direction of the spindle 16 to prevent thrust loads from being applied to the bearing, but is maintained rigid in the radial direction due to the noncompressibility of the diaphragm 20. As a result, the tendency of the spindle 16 to tilt from its central axis is minimized.
