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.
1. Rolling bearing structures and types 1-1 Structure Rolling bearings (bearings hereinafter) nor-mally comprise bearing rings, rolling elements and a cage. (see Fig. 1-1) Rolling elements are arranged between inner and outer rings with a cage, which retains the rolling elements in correct relative position, so they do not touch one another.
Design of bearing arrangements : Roll neck requirements In most rolling mill applications WD four-row 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,
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
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 .
Roll neck bearings for rolling mill; Download PDF . This bearing is used for rolling mill roll necks. This catalog includes data about countermeasures for damages particular to this application as well as dimensions tables.
Roll neck bearings for rolling mill and relevant products Four-row tapered roller bearing Four-row cylindrical roller bearing Sealed type These bearings, mainly used for work rolls or intermediate rolls, carry both of radial load and axial load at a time. Adjustment of internal clearance is not required, facilitating handling. Open type is also available.

First introduced in 1932, MORGOIL bearings were welcomed by the rolling mill industry where roll neck bearing problems were hampering the development of faster and more powerful rolling mills. MORGOIL Bearings provided higher load capacities, higher speed capabilities, lower power consumption, and longer life than existing bearing choices
Four Row Cylindrical Roller Bearings. Multi-row or 4 row Cylindrical Roller Bearings are primarily designed and used as roll-neck bearings in rolling mills. The four rows of rollers lends itself to carry large radial loads for the given bearing cross section.

Two Row Taperedroller bearings are very common as the back-up 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.
