Spherical roller bearing has two columns of roller, mainly bear radial load, but also can carry axial load in either direction. Have high radial load capacity, especially suitable for overloading or under vibration loading work, but can't afford to pure axial load. This kind of bearing outer ring raceway is spherical shape, so the self-aligning performance is good, can compensate the alignment error.

Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. 

The centre point of the sphere in the outer ring raceway is at the bearing axis. 

Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can becaused, for example, by shaft deflection. 

Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions.
