A bearing assembling and a washing machine having the same are provided to predict frequency changed by shock between a rolling bearing and a bearing housing by using a plurality of protrusions formed on the outer surface of the rolling bearing or/and the inner surface of the bearing housing. A bearing assembly(1) comprises a rolling bearing, a bearing housing(10), and a plurality of protrusions(14). A plurality of balls(2) are aligned between the inner wheel and the outer wheel of the rolling bearing. The rolling bearing is press-fitted to the bearing housing. The protrusions are protruded on the outer surface of the rolling bearing or/and the inner surface of the bearing housing, and form a contact part between the rolling bearing and the bearing housing. |
