Spherical rollers of the thrust self-aligning roller bearing are incline-arranged. Bearings of this kind have a self-aligning property and allow a certain inclination of the shaft because of their spherical raceway on seat rings. As a result, they have a very high capacity to bear axial loads. They also can bear smaller radial loads while bearing axial loads. They are widely used in heavy machinery, such as, steel-rolling mills, heavy-duty machine tools, petroleum rigs, large-sized vertical electric motors for ships and combined development machines.
