There is a contact angle between the ring and the ball of the angular contact ball bearing. The larger the contact angle, the greater the axial load capacity. The smaller the contact angle, the more favorable it is for high-speed rotation, suitable for high-speed and high-precision rotation situations;

In addition, the position of the outer ring groove of the deep groove ball bearing is different from that of the angular contact ball bearing, which is not the center position. The specific value is considered in the design of the angular contact ball bearing and is related to the degree of contact angle;
