Title: Investigation of Low to Medium Load Operating Regimes for Roller Bearings in Heavy Industrial Equipment
Keywords: Friction; Rolling bearings; Support roller

Abstract: Large spherical roller bearings are typically used in heavy low speed industrial applications. This sort of sophisticated bearings has achieved nowadays too high dynamic capacity, thanks to the latest modern bearing production technologies and the usage of highest quality bearing steels. Heavy industrial machines from chemical, mining or cement plants are using such type of bearings. Modern industrial plants require higher reliability of their rotating equipment thus to avoid costly downtimes and expensive repairs. However, some heavily loaded applications still struggle of outages. For the bearing’s selection process is typically used C [kN] basic dynamic load rating, but one additional catalogue parameter looks very important—Pu [kN] fatigue load limit. The ISO 281 standard does not recommend one bearing simply to be selected just on that Pu value, rather advices more investigations to be done how Pu could correlate to specified working conditions. In this case study will be conside
