A spherical roller bearing is a rolling-element bearing that allows rotation with low friction, and allows angular misalignment. Typically these bearings assist a rotating shaft in the bore of the internal ring that may additionally be misaligned in respect to the outer ring. The misalignment is possible due to the spherical inner structure of the outer ring and spherical rollers.

Spherical roller bearings are not actually spherical in shape. The rolling factors of spherical roller bearings are mostly cylindrical in shape, however have a profile that makes them appear like cylinders that have been barely over-inflated.
Construction
Spherical roller bearings consist of an internal ring with two raceways inclined at an angle to the bearing axis, an outer ring with a frequent spherical raceway, spherical rollers, cages and, in certain designs, additionally interior information rings or centre rings. The bearings can additionally be sealed.
