Spherical Roller Bearing

Spherical roller bearing has two rows of rollers, which mainly bear radial load and axial load in either direction. It has high radial load capacity, especially suitable for working under heavy load or vibration load, but can not bear pure axial load. This kind of bearing outer race is spherical, so it has good centering performance and can compensate coaxiality error. There are 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, which has good centering performance. When the shaft is bent or installed eccentrically, the bearing can still be used normally. The centering performance varies with the bearing size series. Generally, the allowable centering angle is 1 ~ 2.5 degrees, This type of bearing has large load capacity. In addition to bearing radial load, the bearing can also bear two-way axial load and has good impact resistance. Generally speaking, the allowable working speed of self-aligning roller bearing is low.
