ABSTRACT:
A system and method for improving lubrication in a fluid dynamic bearing are disclosed. A fluid dynamic bearing comprising a rotor portion and a stator portion is formed. In addition, a lubricating fluid comprising a high pressure lubricant is provided between the rotor portion and the stator portion of the fluid dynamic bearing, wherein the high pressure lubricant provides extreme pressure protection of the rotor portion and the stator portion of the fluid dynamic bearing.
