Features:

Thrust spherical roller bearings are the same as spherical roller bearings, the raceway surface of the seat ring is a spherical surface centered on the point consistent with the central shaft of the bearing, and this kind of bearing roller is spherical type, so it has an automatic self-aligning function and is not very sensitive to coaxiality and shaft deflection. 
Unlike other thrust bearings in the sample, these bearings have a very large axial load capacity and can bear some radial loads along with axial loads, but the radial loads must not exceed 55% of the axial loads.
As long as the loads P and P0 do not exceed 0.05C0 and the shaft washer rotates, the bearing is allowed to have the alignment angles listed in the table below. 
Bearing diameter series self-aligning angle 
Bearing diameter series self-aligning angle 
200 series 1°~1.5° 
300 series 1.5°~2° 
400 series 2°~3°
Smaller values apply to larger bearings, and the permissible spherical angle will decrease as the load increases.
Oil lubrication is generally used when using. This type of bearing is mainly used in hydroelectric generators, vertical motors, propeller shafts for ships, tower cranes, extruders, etc.
