Koyo spherical roller bearing 22213 22214 22215 22216 22217 22218 CA

Spherical roller bearings have two rows of rollers, which mainly bear radial loads, but can also bear axial loads in any 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 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, and the inner ring has two raceways inclined at the same angle to the axis of the bearing. It has good self-aligning performance. When the shaft is bent or installed out of center The bearing can still be used normally at the same time. 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, and the bearing can withstand radial load. The double-acting axial load has good impact resistance. Generally speaking, the allowable working speed of spherical roller bearings is low.
