Angular contact ball insert bearing with base

The utility model discloses an angular contact ball insert bearing with a base. The angular contact ball insert bearing comprises a bearing base and an angular contact ball bearing, and is characterized in that a bearing mounting hole is formed in the bearing base, and the inner surface of the bearing mounting hole is an inner spherical surface; the angular contact ball bearing comprises an outer ring and an inner ring provided with annular channels, and a ball between the annular channels of the inner ring and the outer ring, wherein the outer surface of the outer ring is an outer spherical surface, and the outer spherical surface of the outer ring is matched with the inner spherical surface of the bearing mounting hole in the bearing base. The angular contact ball insert bearing with the base disclosed by the utility model not only can bear radial load but also can bear axial load, or can simultaneously bear joint radial and axial load, and can bear a certain capsizing moment; and in the case of suffering from the capsizing moment, the bearing can automatically center and correct through the outer spherical surface of the outer ring and the inner spherical surface of the bearing mounting hole without increasing the internal burden of the bearing.
