Spherical roller bearings have two rows of rollers, the outer ring shares a spherical raceway, and the inner ring has two raceways. Spherical roller bearings can self-aligning, so they can withstand large alignment errors. In addition to having a high radial load carrying capacity, it can also withstand heavy axial loads acting in two directions. There is no other bearing that can completely replace spherical roller bearings.
