The outer spherical ball bearing is actually a variant of the deep groove ball bearing. It is characterized by the spherical outer diameter surface of the outer ring, which can be matched into the corresponding concave spherical bearing seat to play the role of aligning. The outer spherical bearing is mainly used to bear radial and axial combined loads, which are mainly radial loads. It is not suitable to bear axial loads alone.

The main features of stainless steel outer spherical bearings 1. The outer spherical bearing with seat can work under the condition that the two bearing seats are not coaxial, and the maximum automatic adjustment Angle can reach 2°. 2. Outer spherical bearing with seat has good rotation accuracy; It can be easily re-lubricated. The clearance is larger than that of the same size deep groove ball bearings, so the temperature difference has little influence on its accuracy. 3. The inner diameter of the outer spherical bearing with seat adopts "+" tolerance to form a clearance match with the shaft. The bearing is fixed on the shaft through the top wire, eccentric sleeve or tight sleeve on the upper side of the inner ring, which reduces the accuracy requirements of the shaft and makes it very convenient to install or replace the bearing. 4. Outer spherical bearing with seat is composed of outer spherical bearing and bearing seat. In use, there is no need to design the bearing box, small size, simple structure, can be directly bolted on the design part of the main engine, easy to use. 5. The outer spherical bearing with seat is generally pre-filled with grease and adopts the form of double or three lip seal. It is suitable for use in the occasions with more dust, mud and water and corrosive media, which is conducive to the work of the main engine. 6. Bearing seat as a whole structure, bearing capacity is large, good rigidity, bearing and bearing seat can be exchanged, that is, the same bearing seat can be installed with various types of bearings; Similarly, the same bearing can be matched with various types of bearing seats.
