Spherical roller bearing has two raceways in the inner ring and one spherical raceway in the outer ring, assembly of drum-shaped rollers. It mainly bear radial load, but also can withstand axial load in either direction. with high radial load capacity, especially suitable for heavy work loads or vibration, but can not afford pure axial load. This kind of bearing outer ring raceway is spherical shape, so it's good aligning performance, can compensate concentricity error.
