PURPOSE: A bearing assembly and a spindle motor including the same are provided to prevent damage to components even though the components are in contact with each other by external impact, thereby maximizing the performance and the lifetime. CONSTITUTION: A bearing assembly (100) includes a sleeve (120), a thrust plate (130), a cap member (140), and a rotation center providing unit. The sleeve supports a shaft (100) to be rotated by a medium of oil. The thrust plate is fixed to the shaft to be arranged on the upper side of the sleeve. The cap member, which is arranged on the upper side of the thrust plate, makes an interface of the oil between the trust plate and the cap member and is fixed to the sleeve. The rotation center providing unit is formed to be recessed on the top surface of the cap member in order to provide the rotation center of deformation in case of the deformation of the cap member caused by external impact. |
