Four-row Cylindrical Roller Bearings

Multi-row or four row cylindrical roller bearings are primarily designed and used as roll-neck bearings in rolling mills. The four rows of rollers lends itself to carry large radial loads for the given bearing cross-section. These four row cylindrical roller bearings can be open or sealed.

Because they are normally mounted with an interference fit on the roll neck, four-row cylindrical roller bearings are well suited for rolling mill applications where the rolling speed is high. Because four-row cylindrical roller bearings can accommodate only radial loads, they are mounted together with deep groove or angular contact ball bearings, or with tapered roller bearings (either radial or thrust design) which accommodate the axial loads.

Series of four-row cylindrical roller bearings

Our basic design four-row cylindrical roller bearings are available in several designs. The major design differences between the bearings are the number of inner and outer rings, the ring designs (flange configurations), and the cage design and material.
