This study investigates and characterizes, via thermodynamic laws, a widely employed standard for measuring oxidation-thermal stability of lubricating greases—ASTM 5483—based on first-order chemical kinetics, using pressure differential scanning

Grease aging in a rolling bearing happens primarily during the churning phase due to high shear and temperature caused by macroscopic flow. This study utilizes a temperature profile to quantify the impact of thermo-mechanical aging on grease. Two dif

Five common ball bearing greases were studied using a grease-on-paper test configuration, where the bleeding of greases is described by the dynamics of a driving capillary pressure provided by the paper and its opposing counterpart in the grease matr

Applications operating at high temperatures may suffer from oxidative lubricant degradation. The current test methods to evaluate thermoxidative stability and performance are resource intensive and they often provide results that are difficult to ext

The film thickness decay of grease-lubricated bearings is determined by a loss of lubricant from the bearing. One of these loss mechanisms is base oil evaporation. In this article, a model is presented for evaporation where the volatiles leave the be

The evolution of the film thickness in a grease lubricated rolling bearings is given by a continuous process of loss and replenishment of oil in the rolling track. It is believed that in a long run, the oil film is maintained by the oil that is bleed

Grease life in hybrid bearings is longer than that in all-steel bearings. This will be shown in this article by means of grease life tests with a large number of greases for both deep groove ball bearings (DGBBs) and cylindrical roller bearings (CRBs

The bleed rate of a grease may change over time due to degradation of the thickener microstructure and a decrease in oil content, as oil is released from the grease. In this work, the bleed properties—quantified by the permeability—of five types

Calcium sulfonate complex greases have excellent extreme pressure, antiwear, and anticorrosion properties and are widely applied in rolling bearings, particularly in humid environments. In this article, the shear stability of dry and water-contaminat

The lubricating film formation of greases has been widely studied using single contact ball-on-disc configurations. However, other than for oil, the film formation with grease is governed by starvation, which in a full bearing is clearly different fr
