Self-aligning ball bearings are bearings equipped with spherical balls between the inner ring of two raceways and the outer ring of which the raceways are spherical.

The center of curvature of the outer ring raceway surface is consistent with the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and housing are deflected, they can be adjusted automatically without increasing the bearing burden. Spherical roller bearings can withstand radial loads and axial loads in two directions. Large radial load capacity, suitable for heavy loads and shock loads. The inner diameter of the inner ring is a bearing with a tapered bore, which can be directly mounted. Or install it on the cylindrical shaft using an adapter sleeve and a dismantling sleeve. The cages use steel stamping cages, polyamide forming cages and copper alloy turning cages.

Self-aligning ball bearings are suitable for industries such as heavy loads and shock loads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum, paper, cement, sugar, and general machinery.
