Spherical roller bearings utilize two rows of friction-reducing, barrelshaped rollers located between an outer ring with a spherical raceway and an inner ring composed of two inclined raceways. These bearings are valued for their ability to compensate for misalignment and shock loads due to their raceway geometries, and are used in many heavy-duty industrial applications. There is some difference cage of them. Like the CA, CC, MB, E, EAE4, CDE4, be offered by my company.
