The outer spherical ball bearing is actually an improved version of the deep groove ball bearing. Its characteristic is that the outer diameter surface of its outer ring is spherical, which can fit into the corresponding concave spherical surface of the bearing seat, playing a role in automatic centering. Outer spherical bearings are mainly used to withstand combined radial and axial loads, mainly radial loads, and are generally not suitable for bearing axial loads alone.
Outer spherical ball bearing with seat
A spherical bearing with a seat is a bearing unit that combines a rolling bearing with a housing. Most outer spherical bearings make the outer diameter into a spherical surface and are installed together with a bearing seat with a spherical inner hole. There are various structural forms, with good universality and interchangeability.
At the same time, this type of bearing also has a certain degree of self-alignment in design, convenient installation, and a dual structure sealing device, which can work in harsh environments. The bearing seat is generally cast. Commonly used seats include vertical seat (P), square seat (F), convex square seat (FS), convex circular seat (FC), CZPT seat (FL), circular seat (C), slider seat, etc. (T).
Outer spherical bearings with seats are divided into bearing cores and bearing seats. From the name, it is called bearing center plus bearing seat. For example, an outer spherical bearing with a set screw UC205 and a vertical seat is called UCP205. Due to the strong interchangeability between the outer spherical bearing and the seat, the bearing core can be freely assembled in bearing seats of the same specification and different shapes.
