Self-aligning roller bearings can adapt to the severe environment and working condition, are mainly designed to bear very heavy radial loads and heavy axial loads, have extremely high impact load resistance, and can realize full-capacity load through self-aligning functions thereof in the case that an installation axes are misaligned. In outer rings of the bearings, two rows of rollers have a common spherical raceway. Thus, they can be automatically aligned in a wide range of swing angles and can accept axis alignment errors within a certain range. Spherical Roller Bearings The bearings are generally designed in two columns. The outer rings of the two columns of rollers have a common spherical raceway. In the case that the accurate concentricity between a shaft and two shafts of a bearing seat is difficult to obtain, the structural design has very important practical significance.
