The cylindrical roller bearings are separable bearing. The rollers contact raceway in the form of line-contact. Therefore, the radial load carrying capacity is better and it applies to heavy load, impact load or high rotating speed environment. This bearing is easy to be installed and disassembled, especially when the inner ring and outer ring need to interference fit with shaft and housing.

Metallurgical equipment must require highly efficient, stability, longest life components to ensure the operation, and in all the parts, bearing is the critical parts and components.
Four-row cylindrical roller bearings are almost exclusive to metals industry and carry heavy radial loads in steel, aluminum and other metal rolling mills. Four-row cylindrical roller bearings have an extremely high radial load capacity, but no thrust capacity.
This bearing type is mostly used in roll neck and work roll applications in the metal rolling industry.
