Abstract
A hydrodynamic bearing assembly for a disk storage unit includes a hub having a longitudinal axis disposed in a cavity formed between a base and a cover. A pair of balls is disposed within a pair of corresponding sockets with each being aligned opposite one another along a longitudinal axis of the hub. The pair of sockets are affixed to the base and cover plates, respectively, while the pair of balls are affixed to the hub. The clearance space between each ball and socket is filled with a liquid lubricant held in place by a surface tension seal. At least one of the sockets or balls is threadably attached so as to allow adjustment of the clearance space.
