Spherical roller bearings have two rows of symmetrical spherical rollers, the outer ring has a common spherical raceway, and the inner ring has two raceways inclined at an angle to the bearing axis. It has good alignment performance. When the shaft is stressed The bearing can still be used normally when bent or installed out of center. Alignment varies with bearing size series. Generally, the allowable alignment angle is 1~2.5 degrees.
This type of bearing has a large load capacity, except for the radial load. The outer bearing can also withstand the axial load acting in both directions and has good impact resistance. Generally speaking, the allowable working speed of the spherical roller bearing is lower.
