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.
Aligning ball bearings are bearings equipped with spherical balls between the inner ring of two raceways and the outer ring with a spherical raceway. The center of curvature of the outer ring raceway surface is consistent with the center of the bearing, so it has the same alignment function as a self-aligning ball bearing. When the shaft or housing deflects, it can be automatically adjusted without increasing the burden on the bearings. Spherical roller bearings can bear radial loads and axial loads in two directions. It has large radial load capacity and is suitable for situations with heavy loads and impact loads. Bearings with a tapered bore in the inner ring can be installed directly. Or use an adapter sleeve or disassembly barrel to install it on the cylindrical shaft. The cage uses steel plate stamping cage, polyamide forming cage and copper alloy machined cage.

However, the relative inclination of the inner and outer rings shall not exceed 3 degrees.
It can bear large radial load and certain axial load. The outer ring raceway of this type of bearing is spherical, so it has self-aligning performance. When the shaft is bent or tilted due to force and the relative tilt between the center line of the inner ring and the center line of the outer ring does not exceed 1° to 2.5°, the bearing can still work.
