Four-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. Because they are normally mounted with an interference fit on the roll neck, four-row cylindrical roller bearings are well suited for rolling mill Four row cylindrical roller bearings 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.

Because of their high number of rollers, four-row cylindrical roller bearings are suitable for very NSK 6004du2 Bearing heavy radial loads.The separable components of the four-row cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.
