Two Row Tapered roller bearings are very common as the backup thrust bearing in a rolling mill or as the roll neck in lighter duty rolling mills. Two row tapers are designed in a variety of styles for different applications. Converging bearings (TDI,TDIE,TDIS) consist of one double cone and two single cups possibly with a cup spacer.
Grinding the surface of raceway and roller at same time after the inner ring is pressed on roller neck, it favors the improvement of rolling precision and the free adjustment of mounting clearance of bearings. These bearings are mostly applied to the working roller and backup roller of rolling mills .
ROLLING MILLS. NTN''s rollneck bearings feature a fourrow, taper setup that effectively supports both radial and axial loads. Most bearings are available with seals, and the bearing boxes can be designed in compact configurations since thrust bearings are eliminated.
After a roll change or a mill stop rolls need some time to return to stable thermal conditions, every new bar entering the mill creates an impact, ... and sometimes there are really severe rolling accidents, due to faults by operators, weak rolled materials with internal defects, or because
rolling mills, Timken® sealed roll neck bearings are available in a wide range of sizes from 7 inches 28 inches (180 mm710 mm) bore. advanced seals increase Mill uPTiMe Timken engineering experience and knowledge of roll neck applications are reflected in the new sealed roll neck bearing design.

tapered roller bearings are designed specifically to offer outstanding performance in the most demanding rolling mill applications. Extensive OE and Service Experience NTN has decades of experience as a trusted supplier to steel mill facilities at both the OE and service levels. NTN produces roll neck bearings in both the United
but use a longer roll. Bearings in the 86 series can accommodate higher loads in the same mill housing size and can be cost effective but use a longer roll and have higher roll neck stresses. Once a size is determined, check that the minimum acceptable roll diameter (Emin) is equal to or below the minimum backup roll diameter for the mill.
Fourrow 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, fourrow cylindrical roller bearings are well suited for rolling mill applications where the rolling .

maximize the load capacity with minimum space, and is widely used for roll neck of lower, medium speed rolling mills. The bearing of this type is made up of one double outer ring, two single row outer rings, two double inner rings and inner ring spacer/outer ring spacer. Since each component is not interchangeable, it is necessary to assemble each
The leader sections for the multiple slit rolling process, square, rectangular or round have to be of very close tolerance. This requires: * Correct pass profile in the rolls * Correct roll gap to ensure no overfill * Correct pass alignment between top and bottom rolls * Sound roll neck bearings and positive roll location to avoid axial flow

A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18.
Design of bearing arrangements : Roll neck requirements In most rolling mill applications WD fourrow tapered roller bearings are mounted with a loose fit on the roll neck. The roll neck journal and the axial abutment for the inner rings must have a certain minimum hardness. The recommended hardness is,
