The outer spherical ball bearing is actually a variant of the deep groove ball bearing. Its characteristic is that its outer ring outer diameter surface is spherical, which can be fitted into the corresponding concave spherical surface of the bearing seat to play the role of centering. The outer spherical bearing is mainly used to bear the radial and axial combined load mainly based on radial load, and generally it is not suitable to bear the axial load alone. Its basic performance is similar to that of deep groove ball bearings, but since such bearings are mostly used in relatively rough machines, the installation positioning is not accurate enough, the axial alignment of the shaft and the seat hole is poor, and the accuracy of the bearing itself is not high enough. Some structures are also rough, so the actual performance of the performance is lower than the deep groove ball bearings of the same specifications. Such bearings can be fitted with inner and outer rings, respectively. The outer spherical bearing is a bearing unit that combines a rolling bearing with a bearing housing. Most of the outer spherical bearings are made of a spherical surface and are mounted together with a bearing housing with a spherical inner hole. The structure is various, and the versatility and interchangeability are good. At the same time, these bearings are also designed with a certain degree of self-alignment, easy to install, and have a double-structured sealing device that can work in harsh environments. The bearing housing is typically cast. Commonly used seats are vertical seat (P), square seat (F), boss square seat (FS), boss circular seat (FC), diamond seat (FL), ring seat (C), slider seat（T)etc.
