One of the most important factors influencing ball bearings service life is   its internal radial clearance. However, this parameter is also very complex   because it depends on applied radial load and ball bearings dimensions,   surface finish and manufacturing materials. Thermal condition of ball   bearings also significantly affects internal radial clearance. Despite many   researches performed in order to find out relevant facts about different   aspects of ball bearings thermal behaviour, only few of them are dealing with   the real working conditions, where high concentration of solid contaminant   particles is present. That’s why the main goal of research presented in this   paper was to establish statistically significant correlation between ball   bearings temperatures, their working time and concentration of contaminant   particles in their grease. Because of especially difficult working   conditions, the typical conveyor idlers bearings were selected as   representative test samples and appropriate solid particles from open pit   coal mines were used as artificial contaminants. Applied experimental   methodology included thermographic inspection, as well as usage of custom   designed test rig for ball bearings service life testing. Finally, by   obtained experimental data processing in advanced software, statistically   significant mathematical correlation between mentioned bearings   characteristics was determined and applied in commonly used internal radial   clearance equation. That is the most important contribution of performed   research - the new equation and methodology for ball bearings internal   clearance determination which could be used for eventual improvement of   existing bearings service life equations.
