Self-aligning ball bearings, with seals on both sides, have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.
