Features of Self-aligning ball bearings NSK Self-aligning ball bearings series (contains model 2304)

The outer ring of a self-aligning ball bearing has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center. This type is recommended when the alignment of the shaft and housing is difficult and when the shaft may bend. Since the contact angle is small, axial load capacity is low.
Pressed-steel cages are usually used
Application: Pumps / Fans and blowers / Powertrain /Gear /Material handling
