Self-Aligning Ball Bearing

Self-aligning ball bearings are designed to accommodate misalignment and shaft deflection, ensuring smooth operation even in challenging conditions. Featuring two rows of balls and a common spherical raceway in the outer ring, these bearings automatically adjust to misalignments without excessive friction or heat buildup. They are ideal for applications where shaft bending or mounting inaccuracies are common, such as in agricultural machinery, conveyors, and textile equipment. Available in both open and sealed designs, our self-aligning ball bearings provide excellent durability, low maintenance, and enhanced operational efficiency.
