Abstract
The invention discloses a slotting bearing outer ring. The slotting bearing outer ring comprises an outer ring body. An outer ring raceway is arranged on the inner ring face of the outer ring body. The slotting bearing outer ring is characterized in that a wedge opening groove is formed in the portion, close to the inner ring face of the outer ring body, of the end face of one side of the outer ring body; and an opening of the wedge opening groove is located in the inner ring face of the outer ring body, and a penetrating crack which penetrates the outer ring body in the axial direction and passes the center line of the wedge opening groove is formed in the outer ring body. The invention further discloses a manufacturing process of the slotting bearing outer ring and a bearing with the bearing outer ring. Due to the fact that the wedge opening groove is formed in the outer ring body and the penetrating crack is formed in outer ring body, the ball filling angle of steel balls can be increased to 330 degrees to 350 degrees in the assembling process of the steel balls, in other words, basically the steel balls are densely distributed on a steel ball raceway formed by the outer ring raceway of the bearing outer ring and an inner ring raceway of a bearing inner ring, and the loading capacity of the bearing is improved effectively. It is tested that the loading capacity of the bearing is improved by at least over 40%.
