Method of making fluid dynamic bearing

摘要

A method of making a fluid dynamic bearing (10) includes the flowing steps. At least two bearing parts (10a, 10b) are firstly provided. Each of the bearing parts has its shape corresponding to a portion of the fluid dynamic bearing to be formed. Then, the bearing parts are combined to form a profile of the fluid dynamic bearing to be formed. Finally, the combined bearing parts are sintered to form an integral body. The fluid dynamic bearing is thus obtained.
