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 .
