Self aligning spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceway

Spherical Roller Bearing is a kind of bearing which can sustain heavy load or oscillatory load. And it can offset the factor for misalignment because of the deviation between the axis bending in shape and the bearing installment parties. This bearing can maintain more heavier load capacity and lower limit rotating speed. It can be widely applied to heavy machinery, such as mine, steel, and maritime transportation

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 be caused, for example, by shaft deflection. Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions

Bearing performance is not only determined by load or speed ratings. There are a number of other factors that contribute to bearing performance. To a large extent, performance is influenced by the geometry of the rollers, raceways and cages, the heat treatment, as well as the surface finish of all contact surfaces.
