The invention relates to a fluid dynamic bearing system that has a
stationary sleeve, a stationary shaft disposed in the sleeve and bearing
disks disposed on the sleeve and shaft which form an annular disk-shaped
space between each other in which an annular disk-shaped component is
disposed. A bearing gap filled with a bearing fluid is formed between the
stationary and the rotating bearing construction. The bearing system
further comprises at least one radial bearing formed between the outer
circumference of the shaft and the inner circumference of the annular
disk-shaped component, at least two axial bearings formed by the two end
faces of the annular disk-shaped component and the first end faces of the
bearing disks opposing these; and capillary seals to seal the two open
ends of the bearing gap, at least one capillary seal comprising a
reservoir that is at least partly filled with bearing fluid and is formed
between the surfaces opposing each other of the rotor hub, or a component
connected to the rotor hub, and an end face of one of the bearing disks.
