NTN Self-Aligning Ball Bearings 1220S

NTN Self-Aligning Ball Bearings, the outer ring raceway of self-aligning ball bearings forms a spherical surface whose center is common to the bearing center. The inner ring of the bearing has two raceways. The balls, cage, and inner ring of these bearings are capable of shifting in order to compensate for a certain degree of misalignment with the outer rings. As a
result, the bearing is able to align itself and compensate for shaft / housing finishing unevenness, bearing fitting error, and other sources of misalignment as shown in Fig. 1.
Since axial load capacity is limited, self-aligning ball bearing are not suitable for applications with heavy axial loads.
