The utility model relates to the technical field of bearings, and particularly relates to an angular contact ball bearing with cage covers. The angular contact ball bearing with cage covers is provided with a bearing outer ring and a bearing inner ring, wherein a cage is arranged between the bearing outer ring and the bearing inner ring; multiple balls are inlaid on the cage; annular cage covers are arranged at the two ends of the cage; the angle alpha formed between the connection line of the contact points between the balls and the bearing outer ring and bearing inner ring and the radial direction is 10-30 degrees. With simple structure and reasonable design, the angular contact ball bearing provided by the utility model can bear radial load and axial load at the same time, and can work at a relatively high speed; the larger the contact angle is, the higher the axial bearing capacity goes; with the cage covers, the dustproof effect is good.
