Spherical Roller Bearing has two rows of rollers. It mainly bears radial load and 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 raceway of this kind of bearing is spherical, so its alignment performance is good and it 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 inclined axes of the bearing.
Angular raceway has good alignment performance. bearing can still be used normally when the axle is bent or installed with different centers. The alignment varies with the bearing size series. Generally, the allowable alignment angle is 1-2.5 degrees. This type of bearing has a large load capacity. Besides the radial load, the bearing can also bear the axial load of bidirectional action and has better impact resistance. Generally speaking, the allowable working speed of Spherical Roller Bearing is lower.
