Spherical rollers are put between the spherical raceway on the outer ring and the two grooves on the inner ring for there bearings. Since the center of the arc raceway on the outer ring is the same as the center of the whole bearing arrangement, there bearings are self-aligned and automatically adjust the bending of the shaft and housing and the eccentricity. The bearings can carry radial load and axial load in double directions. The especial radial load carrying capability makes there bearings suitable for heavy load and shock load carrying.
