Self-aligning ball bearings are a type of rolling-element bearing designed to accommodate misalignment between the shaft and housing. They feature two rows of balls with a common spherical raceway in the outer ring, enabling them to self-align under load. This capability makes them suitable for applications where shaft deflection or misalignment is common, such as in conveyor systems, agricultural machinery, and industrial gearboxes. Self-aligning ball bearings offer improved performance and longevity by reducing friction and wear, thereby enhancing the overall reliability and efficiency of rotating machinery.
