Roll neck bearings for rolling mills are limited in size by the roll neck diameter and minimum roll diameter. Four-row tapered roller bearings are designed to have the
highest possible load rating within this limited space. This type of bearing has two double-cone assemblies, two cups, one double cup, and three spacers. The bearings have their internal clearance adjusted for each set, so it is necessary to assemble them correctly in accordance with their serial numbers and matching symbols.
Various part numbers in stock, welcome inquiry. Fast shipment within 2-3 working days.
