Spherical roller bearings have two row rollers and sphered raceway on outer raceway. They can accommodate heavy radial loads and heavy axial loads. They are mainly used for the applications where varying heavy loads or misalignment are present. They are commonly used in paper mills, rolling mills, mining and construction machines, railway vehicles, presses, and vibrating screens.
