Self-aligning ball bearing is ideal for applications in which the shaft and housing are misaligned. Designed to accommodate a three-degree misalignment, self-aligning ball bearings minimize friction and frictional heat. Due to the relatively small contact angle, axial load capacities of these bearings are lower than, for example, that of angular contact bearings. 

Self aligning ball bearings are suitable for bearing heavy and impact loads, precision instruments, low noise motors, automobiles, motorcycles, metallurgy, rolling mills, mines, petroleum, papermaking, cement, sugar squeezing and other industries, as well as general machinery.
