Self-aligning ball bearing

Self-aligning bearing refers to the ring raceway is spherical and is adaptable to the bearing with angular deviation movement between the inner and outer raceways’ axis. It mainly undertakes radial load. It can also undertake a little two-way axial load. 

Self-aligning bearing is the bearing in the shape of spherical roller. It is between the two raceways’ inner-ring and the outer-ring of spherical raceway. It can undertake great radial load and some axial load. The outer-ring raceway of such bearing is sphere. Hence, it has aligning performance.
