Spherical Roller Bearings

Spherical Roller Bearings have two rows of rollers that are mainly subjected to radial loads, but also axial loads in either direction. It has a high radial load capacity, which is especially suitable for working under heavy loads or vibration loads, but cannot withstand pure axial loads. The raceway of the outer ring of this type of bearing is spherical, so its self-alignment 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, the inner ring has two raceways inclined to an angle with the bearing axis, has good self-alignment performance, when the shaft is bent or installed differently when the bearing can still be used normally, the self-alignment varies with the bearing size series, the general allowable self-alignment angle is 1~2.5 degrees, the load capacity of this type of bearing is larger, in addition to being able to bear the radial load, the bearing can also bear the axial load of two-way action, and has good impact resistance, In general, spherical roller bearings are allowed to operate at a lower operating speed.
