Bearing action impact resistance speed
Self aligning roller Bearing has two rows of rollers, which mainly bear the radial load and the 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. The outer race of this kind of bearing is spherical, so its centering performance is good and can compensate the coaxiality error.
The self-aligning roller bearing has 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. When the shaft is forced to bend or the installation is not concentric, the bearing can still be used normally. The self-aligning performance varies with the bearing size series. Generally, the allowable self-aligning angle is 1 ~ 2.5 degrees, and the load capacity of this type of bearing is large, In addition to bearing the radial load, the bearing can also bear the axial load of two-way action and has good impact resistance. Generally speaking, the Bearing allowable working speed of self-aligning roller bearing is low.
