spherical roller bearings are self-aligning function, but is also very strong. Spherical Roller Bearings are two rows of rollers, in the outer ring, there is a sharing of spherical roller Road, there are two Inner Raceway, with the bearing axial tilt into a relative perspective. This is the bearing attractive design features, in many demanding applications can not be replaced. CIE spherical roller bearings are open, sealed and applied to the specific application of bearings.
