Spherical Roller Bearing

Spherical roller bearings are bearings with spherical rollers assembled between an inner ring with two raceways and an outer ring with spherical raceway. The bearings possess two rows of rollers, mainly withstanding radial load, and at the same time withstanding any of an axial load direction. With high radial load capacity, it is especially suitable for working under heavy load or vibration load. The bearing can also withstand the axial load in both directions, but it cannot bear pure axial load. The outer ring raceway of the spherical roller bearing is spherical, so its self-aligning performance is good and it can compensate the coaxiality error. Generally speaking, the allowable working speed for spherical roller bearings is low.
