The present study aims at predicting the maximum temperature in line contacts depending
on operating conditions. For this purpose, a thermo-elastohydrodynamic lubrication (TEHL) …

While a rolling element bearing is operating, the lubricating film is desired to maintain a
sufficient thickness to avoid asperity contact between surfaces. When using grease as …

Understanding the relevance and significance of the various replenishment mechanisms in
grease-lubricated bearings is very important in choosing the appropriate lubrication strategy …

The accurate prediction of friction in highly loaded concentrated contacts is one of the most
challenging aspects of thermal elastohydrodynamic (TEHD) simulation. The correct …

The contact geometries encountered in rolling element-outer race or inner race contacts in
real bearings are not involved in conventional ball-on-flat disc configurations. However, the …

Grease-lubricated rolling element bearings that perform oscillating motion are often prone to
False Brinelling. Previous investigations on oscillating open contacts, ie no presence of a …

The bearing cage played a pivotal role in affecting the lubricant redistribution and lubrication
states. In this study, a cage unit is incorporated into an optical ball-on-disc apparatus for the …

A new nozzle structure based on oil–air lubrication is proposed to address the problem of
fluctuating oil supply limitations that can occur during the transfer of lubricant in the …

Friction causes mechanical parts' wear and even failures. Using lubricating grease can
effectively diminish the friction for bearing and associated components. However, along with …

The soaring prices and physiological toxicity of lithium-based grease make polyurea grease
a promising alternative due to its balanced cost and performance. Employing preformed …
