Thrust self-aligning roller bearing is identical to self-aligning roller bearing. The seat ring raceway surface is sphere whose center is points consistent with the bearing central axis. The roller of this type of bearing is spherical. So it is provided with self-adjusting function. It is not sensitive to concentricity and shaft flexure.
Different from other thrust bearings in the sample, this type of bearing is provided with super axial load capacity, and it can be subject to definite radial load while being subject to axial load. But the radial load can not exceed 55% of the axial load.
The bearing allows aligning angle listed in the table bellow as long as P and P0 do not exceed 0.05C0 and the blowout patch rotates
