Self Aligning Ball Bearings

Self-aligning ball bearings have a spherical outer ring raceway, the center of whose curvature meats that of the bearing itself, so that the inner ring, ball and cage continue to rotate, aligning themselves if they have become misaligned within design limits. This type of bearing is suitable when the displacement of the centers around which the shaft and housing rotate and shaft deflection are likely to occur. Sometimes, they feature a tapered bore to fit the shaft with an adapter assembly. Also, it’s possible to get these bearings with integral rubber lip seals.
