Spherical Roller Bearings

Spherical Roller Bearings bearing has two rows of rollers, mainly bearing radial load, and also bearing axial load in any direction. It has high radial load capacity, especially suitable for working under heavy load or vibration load, but can not bear pure axial load. The outer race of this type of bearing is spherical, so it has good centering performance and can compensate for 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. It 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 a large load capacity, In addition to bearing radial load, the bearing can also bear axial load of two-way action, and has good impact resistance. Generally, the allowable working speed of self-aligning roller bearing is low.
