What types of spherical bearings are there?

The outer spherical ball bearing is actually a variant of the deep groove ball bearing. Its characteristic is that the outer diameter surface of its outer ring is a spherical surface, which can be fitted into the corresponding concave spherical surface of the bearing seat to achieve alignment. Outer spherical bearings are mainly used to bear the combined radial and axial loads, which are mainly radial loads. Generally, they are not suitable to bear the axial load alone.
The outer spherical bearing with seat is a bearing unit that combines a rolling bearing with a housing. Most outer spherical bearings have a spherical outer diameter and are installed together with a bearing seat with a spherical inner hole. They have various structural forms and have good versatility and interchangeability.

At the same time, this type of bearing also has a certain degree of alignment in design, is easy to install, has a dual-structure sealing device, and can work in harsh environments. Bearing seats are generally cast. Commonly used seats include vertical seat (P), square seat (F), boss square seat (FS), boss round seat (FC), diamond seat (FL), ring seat (C), slider seat, etc. ( T).

The outer spherical bearing with a seat is divided into a bearing core and a bearing seat. In terms of name, it is called the bearing center plus the bearing seat. For example, an outer spherical bearing with a set screw UC205 with a vertical seat is called UCP205. Because of the strong interchangeability of the outer spherical bearing with seat, the bearing core can be freely assembled in the bearing seat of the same specification and different shape.
