Self-aligning ball bearing outer ring raceway processed into spherical, with self-aligning performance. Is mainly used to bear radial load, the bear radial load at the same time, also can take a small amount of axial load, but usually can't bear to pure axial load, its limit rotational speed is low deep groove ball bearings. These bearings used in more easily bent double under the action of a load on the supporting shaft, and the two bearing seat hole cannot ensure strict alignment widget, but the relative slope of the center line of the center line of the inner ring and outer ring must not exceed 3? . This kind of bearings for steel ball and raceway contact area is small, and the load capacity is low, service life is short, and there will be the trend of the spherical roller bearing is replaced.
