Spherical bearing

The self-aligning roller bearing has two rows of rollers, one common spherical raceway in the outer ring and two raceways in the inner ring, which are inclined to an angle relative to the axis of the bearing. This ingenious structure makes it have automatic alignment performance, so it is not susceptible to the influence of the angle between the shaft and the bearing housing on the error or the bending of the shaft. It is suitable for the occasion where the angle error is caused by the installation error or the bending of the shaft. The bearing can bear not only radial load, but also biaxial load.
