Spherical Roller Bearings are designed to provide for heavy loads, shaft misalignment and deflection. They contain two symmetrical or asymmetrical rows of barrel-shaped rollers which align themselves in the outer race sphered track. They are therefore able to carry very heavy radial loads and axial loads in either direction.

These bearings exist in MB version (two-piece cage), CA version (single piece brass cage) and in the improved GMEX version.
