Four-Row Cylindrical Roller Bearing
Four-row cylindrical roller bearings for rolling mill work rolls and backup rolls — maximum radial load capacity for hot strip mills, plate mills, and section mills. Factory direct from ANDE bearing manufacturer.
Technical Overview
Four-Row Cylindrical Roller Bearings are designed for the most demanding heavy-load applications in steel rolling mills. The four-row configuration distributes extremely high radial loads across four rows of cylindrical rollers, providing the maximum radial load capacity in a compact design. These bearings are primarily used in the bearing chock assemblies of work rolls and backup rolls in hot strip mills, plate mills, and section mills. ANDE four-row cylindrical roller bearings are manufactured from premium bearing steel with precision-machined raceways and robust brass or steel cage designs for reliable operation under the extreme conditions of continuous steel rolling. We provide interchangeable size and performance benchmarking solutions that can directly replace equivalent four-row cylindrical roller bearings from major international manufacturers.
