Self-aligning ball bearings have two types of structure: cylindrical hole and conical hole. The material of the cage includes steel plate and synthetic resin. Its characteristic is that the outer ring raceway is spherical, with self-alignment, which can compensate for errors caused by different heart degrees and shaft deflections, but the relative inclination of the inner and outer rings must not exceed 3 degrees.

It mainly bears radial load and can bear small axial load. The axial displacement of the shaft (housing) is limited to the clearance limit, and it has self-aligning performance, allowing normal work under the condition that the inner and outer sides are relatively inclined. It is suitable for parts where the support seat hole cannot strictly guarantee the coaxiality.
Self-aligning ball bearings are suitable for bearing heavy and shock loads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum, papermaking, cement, sugar pressing and other industries and general machinery.
