Self-aligning ball bearings are a type of rolling element bearing that can accommodate misalignment between the shaft and housing. This type of bearing has two rows of balls with a common spherical raceway in the outer ring. This design allows the inner ring to rotate freely in relation to the outer ring, which can compensate for misalignment between the shaft and housing.
Self-aligning ball bearings are commonly used in applications where shaft deflection or misalignment is likely to occur, such as in conveyor systems, agricultural machinery, and mining equipment. They can also handle radial loads, and in some cases, axial loads in both directions.
Overall, self-aligning ball bearings provide reliable and low-friction performance, making them a popular choice in many industrial applications.
