Self-aligning roller bearing
Spherical roller bearings are self-aligning roller bearings. have double row rollers, the outer ring has a shared spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis.
They are double row, self-retaining units comprising solid outer rings with a concave raceway, inner rings with a cylindrical or tapered bore and ball and cage assemblies. This ingenious structure enables it to have self-aligning performance, so it is not easily affected by the angle between the shaft and the bearing box seat on the error or the shaft bending, and is suitable for the occasions where the installation error or the shaft deflection causes the angle error. In addition to radial loads, the bearings can also withstand axial loads acting in both directions.
