Spherical Roller Bearings
The self-aligning roller bearing has two rows of symmetrical spherical rollers, which mainly bear radial load, but also can bear axial load in any direction. The raceway of the bearing outer ring is spherical, so its self-aligning performance is good. The self-aligning performance varies with the bearing size series. Generally, the allowable self-aligning angle is 1 ~ 2.5 degrees In addition to the radial load, the bearing can also bear the axial load of two-way action, and it has better impact resistance. Generally speaking, the working speed of self-aligning roller bearing is lower. It is suitable for working under heavy load or vibration load.
