Spherical Roller Bearing

Spherical roller bearings have two rows of rollers, which mainly bear radial loads, and can also bear axial loads in either direction. It has high radial load capacity, especially suitable for working under heavy load or vibration load, but cannot bear pure axial load. The outer ring raceway of this type of bearing is spherical, so its self-aligning performance is good, and it can compensate for the 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 self-aligning performance. The bearing can still be used normally, and the centering performance varies with the bearing size series. Generally, the allowable centering angle is 1~2.5 degrees. The load capacity of this type of bearing is large, and the bearing can withstand radial load in addition to radial load The axial load acting in both directions has good impact resistance. Generally speaking, the allowable working speed of spherical roller bearings is low.
