Self-aligning ball bearings are composed of two inner ring raceways and the outer ring is made of a spherical roller which is between the drum and is equipped with roller bearings. The outer ring raceway surface curvature center is aligned with the bearing center line, and they therefore have self-aligning ball bearings with the same self-aligning feature. In the shaft, deflection occurs when the shell can be adjusted without increasing the burden bearing. Spherical roller bearings can bear radial loads and axial loads in two directions. The amount of radial load capacity that an aligning ball bearing can sustain is suitable for a heavy load and for impact load conditions. The inner diameter is composed of tapered bore bearings that can be installed directly or installed using the adapter kit in the cylindrical shaft tube. The Cage uses steel stamping in order to form the polyamide and copper alloy cage car system.

The self-aligning ball bearing can bear not only a far greater radial load, but also it is able to bear the axial load. This kind of bearing has an outer ring raceway which is spherically shaped, aligning it with the force when the shaft is bent or tilted. The inner and outer ring of the center line of the relative inclination which will still allow the bearing to work should not exceed more than 1 degree- 2.5 degrees.
