Multi-objective optimization in geometric design of tapered roller ...
To improve the fatigue, wear and thermal based failures of Tapered Roller Bearings (TRBs) a multi-objective optimization technique has been proposed. Objective functions considered are: the dynamic capacity (Cd) that is related to fatigue life, the elasto-hydrodynamic minimum film thickness (hmin) that is associated to the wear life, and the maximum bearing temperature (Tmax) that is related ...

Design considerations | SKF
Design considerations Loose fit on roll necks and helical groove in the bore In most rolling mill applications, four-row tapered roller bearings are mounted with a loose fit on the roll neck. This enables quick roll changes. However, loose fits have the disadvantage that the inner rings turn on their seats under load.
