Self aligning roller bearings have two rows of rollers, which mainly bear radial loads and can also withstand axial loads in any direction. Has high radial load capacity, especially suitable for working under heavy loads or vibration loads, but cannot withstand pure axial loads. The outer raceway of this type of bearing is spherical, so its centering performance is good and can compensate for coaxiality errors. There are two rows of symmetrical spherical rollers, with the outer ring having a shared spherical raceway and the inner ring having two raceways tilted at an angle to the bearing axis, which have good centering performance. When the shaft is bent or installed unevenly, the bearing can still be used normally. The centering performance varies with the size series of the bearing, and the generally allowable centering angle is 1-2.5 degrees. This type of bearing has a large load capacity, In addition to bearing radial loads, bearings can also withstand axial loads acting in both directions and have good impact resistance. Generally speaking, self-aligning roller bearings allow for lower working speeds.
