1. Radial loadability is high
2. Self-aligning performance is good
3. High precis

Self-aligning roller bearing has two rows ofspherical rollers, the outer race is provided with a common concave sphericalraceway, while the inner race is provided with two concave spherical racewaysthat form an angle with the bearing axis. The curvature center of the outerraceway is consistent with the bearing center. The self-aligning roller bearingis self-adjusted, and it is not affected by non-centering or shaft deformationflexure of shaft and bearing block, so it can compensate the concentricity errorcaused by these reasons. Except being subject to radial load, this type ofbearing can also be subject to bidirectional axial load and their combinationload. The load capacity is large, and the bearing is provided with preferableshock resistant capacity. Self-aligning roller bearings are mainly applied onmechanical equipments of steel, mine, paper making, shipping, textile machinery,coal mill and electric power industries. It is one of the bearings most widelyused in mechanical industry.
