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. These four-row cylindrical roller bearings can be open or sealed. The four rows of rollers lend themselves to carrying large radial loads for the bearing cross-section.
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 lend themselves to carrying large radial loads for the bearing cross-section. These four-row cylindrical roller bearings can be open or sealed. Because they are usually 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 tapered roller bearings (either radial or thrust design), which accommodate the axial loads.
