Rolling Mill Bearings mainly include Four-Row Cylindrical Roller Bearings, Four-Row Tapered Roller Bearings, Double-Row Tapered Roller Bearings (TDI Type and TDO Type), and Screw-down Bearings.In rolling mills, multi-row cylindrical roller bearings are used to accommodate radial loads in work roll and back-up roll bearing arrangements. The multi-row cylindrical roller bearings are particularly suitable for high rolling speeds and the heaviest rolling forces. For highest accuracy demands, the inner rings in dedicated execution can be ground together with the roll body for exact run-out. Bearings with standard tolerances can be paired or special precision bearings can be used for equal load taking, especially for work rolls in thin strip and foil rolling mills.
