Aligning ball bearing is equipped with spherical balls between the inner ring of two raceways and the outer ring of which the raceways are spherical.

Aligning ball bearings have two types of structure: cylindrical hole and conical hole. It is characterized by the spherical shape of the outer ring raceway, with self-alignment, which can compensate for the errors made by the self-aligning ball bearings with different centering degrees and shaft deflections.

The bearing can withstand large radial loads and also certain axial loads.

Applications: precision instruments, low-noise motors, automobiles, motorcycles, general machinery ect. It is the most widely used type of bearing in the machinery industry.
