Thrust self-aligning roller bearing the roller of this kind of bearing is spherical, because the raceway surface of the race is spherical, it has the function of adjusting the center. The axial load capacity is very large, it can bear some radial loads as well as axial loads.

Thrust self-aligning roller bearing can bear both axial and radial loads, but the radial load shall not exceed 55% of the axial load. This kind of bearing has automatic self-aligning performance, so it is not very sensitive to coaxiality and shaft deflection.
