A load variable-typed ball bearing is provided to offer excellent fuel efficiency and to prolong durability or a lifetime under heavy load efficiently. A load variable-typed ball bearing(100) includes a bearing inner ring(103) and an outer ring(105), a plurality of balls(110,130), an actuator ring(107). A plurality of balls are arranged between the inner ring and the outer ring. The actuator ring operates at least a pair of balls. The outer ring has a hydraulic route(106) of the outer ring. The hydraulic route is connected to an outer side of a bearing and formed on an inner side of the outer ring. |
