Spherical roller bearings have two rows of rollers

The spherical roller bearing has two rows of rollers. There is a common spherical raceway on the outer ring, and there are two inner raceways, which form an angle with the bearing axis. The spherical center point of the outer race is located on the bearing axis. Therefore, the bearing is a self-aligning bearing, which is not sensitive to the centering error between the shaft and the bearing seat, which may be caused by shaft deviation and other reasons. The spherical roller bearing is well designed to withstand not only high radial load, but also heavy axial load in two directions
