Generally, fluid dynamic bearing of the spindle motor for HDD is constituted combining two or more radial bearings and thrust bearings. It is filled with lubricating oil between these bearings, and it is thought that these influence each other through lubricating oil during operation. This paper describes the lubricating analysis with consideration to the interaction between radial bearings and thrust bearings which constitute fluid dynamic bearing of the spindle motor for HDD. Lubricating analysis is solving the incompressible Reynolds equation by the finite element method using the model which combined radial bearings and thrust bearings. The influence which the pump-up value of radial bearing has on the characteristics of thrust bearing is discussed.
