Insert ball bearing unit is the rolling bearing and the bearing seat together a bearing unit, its structure forms, good versatility and interchangeability, and such bearing on the design has a certain adjustable mind, easy to install, has the dual structure of sealing device, even under the bad environment can work normally, can see the figure of it in many occasions.
External spherical ball bearing with seat
The outer spherical bearing with seat is a bearing unit that combines the rolling bearing with the bearing seat. Most of the outer spherical bearings are made of the outer diameter of the sphere, and the bearing seat with a spherical inner hole is installed together, the structure of various forms, versatility and good interchangeability.
At the same time, this kind of bearing also has certain centralization in the design, easy to install, has the double structure of the sealing device, can work in the harsh environment. The bearing housing is generally cast. Common seat has vertical seat (P), square seat (F), square seat (FS), convex platform round seat (FC), diamond seat (FL), ring seat (C), slider seat, etc. (T).
Outer spherical bearing with seat is divided into bearing heart and bearing seat, in the name of bearing heart and bearing seat, such as with fixed screw outer spherical bearing UC205 with vertical seat called UCP205. Because of the strong interchangeability of the outer spherical bearing with seat, the bearing core can be randomly assembled in the bearing seat of the same specification and different shapes.

Now let’s talk about the advantages of seat bearing and its selection principles.
Features of bearing with seat:
- Self-centering function
- Large load capacity
3, long service life
- Good sealing performance
5, the structure is stronger
6, easy to install
- Unique design
Selection principle of bearing with seat:
The correct selection of bearing with seat is very important for the performance of bearing and the normal operation of main engine. The following factors should be considered to select the suitable bearing to meet the requirements of the main engine from a variety of bearings and bearing housings.
1) the support/bearing requirements of the structure of the machine itself;
2) The space of the installation part and the size of the shaft;
3) Bearing load (size, direction, nature);
4) Service life and reliability requirements of bearings;
5) Working speed (high and low, positive and negative);
6) the matching nature and fixing method of the bearing and the shaft;
7) Support position, configuration and axial expansion and contraction size;
8) the matching nature of the bearing and the bearing seat;
9) Ambient temperature requirements (high temperature and low temperature resistance);
10) Surrounding medium, dust, moisture, waterproof and other requirements;
11) the importance of re-lubrication;
12) Noise and vibration requirements;
13) the strength requirements of the bearing seat.
