The spherical rollers in the thrust self-aligning roller bearing are arranged obliquely. Because the raceway surface of the race ring is spherical, it has the self-aligning performance. It can allow the shaft to tilt, and the allowable inclination angle is 0.5 ° to 2 ° and the axial load capacity is very large. It can also bear the radial load while bearing the axial load. Oil lubrication is generally used.
