Aligning ball bearings are bearings equipped with spherical balls between the inner ring of two raceways and the outer ring with a spherical raceway. Aligning ball bearings have two structures: cylindrical hole and tapered hole. The cage is made of steel plate, synthetic resin, etc. Its characteristic is that the outer ring raceway is spherical and has self-aligning properties, which can compensate for errors caused by non-concentricity and shaft deflection, but the relative inclination of the inner and outer rings must not exceed 3 degrees.

Purpose of self-aligning ball bearings: Self-aligning ball bearings are suitable for bearing heavy loads and impact loads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum, papermaking, cement, sugar pressing and other industries and general Machinery etc.
