Spherical roller bearings are mainly used to bear radial load, also can withstand a certain amount of axial load, but generally not subject to pure axial load. Kind of bearing outer ring raceway spherical shape, the former residence of aligning performance bearings can still bend or tilt axis by legislation leaving the inner ring centerline and the outer ring of the centerline of the relative inclination of not more than 0.5 ° ~ 2 ° work properly. Principle of its structure with the same characteristics and self-aligning ball bearings, the only difference is that the rolling element spherical roller different rolling elements, and thus its carrying capacity, are widely used in mining and heavy machinery. Kind of bearing can limit the axial displacement of shaft or housing in the axial bearing clearance range. Spherical roller bearings and self-aligning ball bearings, in line with the capacity and speed limit permitted each other alternative.
