22306 CAW33 SPHERICAL ROLLER BEARING22300

Spherical roller bearing has two columns of roller. It mainly bears radial load and also can bear axial load in any direction but can not bear pure axial load. Spherical roller bearing has high radial load capacity, suitable for working under heavy load or vibration load. The outer ring raceway of this kind of bearing is spherical shape so that it has good self aligning performance and can compensate the alignment error.
