Spherical roller bearings are between an inner ring with two roller and the Raceway for the spherical outer ring. Assembly with drum-type roller bearing. Spherical roller bearings have two rows of rollers, the main stand diameter load, but also can stand either direction axial loads. High radial load carrying capacity, especially suitable for overload or working under vibration loading, but cannot be subjected to purely axial load.
