Self-Aligning Ball Bearings

Self-aligning ball bearings is of the double row type. With a spherical outer ring raceway their self-aligning capability allows them to compensate for misalignments, shaft deflections and housing deformations. It can support both the radial and axial load. As the same dimension as the aligning roller bearing, the rotate speed is quicker. The self-aligning ball bearing is mainly used in the shaft which is easy to be bended under the load effect. And Self-aligning ball bearings is also used in the parts of double housing bore which can't guarantee the same axial degree. in the meantime, the incline angle between outer ring and inner ring is within 3 °.
