Product Description

Four-row Cylindrical Roller BearingsMulti-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.

Series of four-row cylindrical roller bearings

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