The self-aligning bearing has two balls, and the outer ring has a common spherical raceway. This gives the bearings self aligning characteristics, allowing for misalignment of the angle of the shaft relative to the bearing seat. Therefore, they are particularly suitable for applications where misalignment may occur due to installation errors or shaft deflection. In addition, the friction force of unsealed self-aligning ball bearings is the lowest among all bearing types.
