BEARING ASSEMBLY AND SPINDLE MOTOR INCLUDING THE SAME

摘要

PURPOSE: A bearing assembly and a spindle motor are provided to prevent the functional degradation of a circulation unit by blocking the inflow of adhesive for combination between a sleeve and a sleeve housing. CONSTITUTION: A sleeve (120) supports a shaft. The sleeve uses oil as a medium. A sleeve housing (130) prevents the leakage of the oil. One or more circulation units (125) are inserted from an outer surface of the sleeve. A curvature radius of the outer surface becomes maximum at a part adjacent to the circulation units.
