Elastohydrodynamically lubricated systems, commonly referred to as elastohydrodynamically lubricated bearings or elastohydrodynamically lubricated contacts, are types of bearings that combine the principles of elastohydrodynamics with hydrodynamic lubrication. This results in a self-acting, dynamically evolving lubrication system.

The occurrence of elastohydrodynamics is generally associated with very high pressures, extremely thin fluid films, and rapid changes in operating parameters. High pressure in elastohydrodynamic contacts has been shown to invoke pressure viscosity effects and distinct elastohydrodynamic limiting conditions. When fluids behave in such cases, it leads to unusual lubricant film properties and rheological behavior, altering the tribological properties of the bearings and enhancing their performance.

Principally, lubrication in such systems ensures load-carrying behavior by preventing contact in individual material surfaces. Severe operating conditions in such bearings call for dense lubrication structures with powerful support. Apart from optimal load-carrying properties, elastohydrodynamic lubrication facilitates reduced wear, rough finishing, wear of the sleeves, severe friction losses, low deformations and possible limiting of the heated bearing.

Common forms of elastohydrodynamically lubricated systems can be prescribed to be sufficiently encapsulated. Its regional conditions also require rigorous conception of all reported elastohydrodynamic design properties. Researchers are diligently experimenting on adaptive elastohydrodynamic models to investigate their relevance under different loading effects. The theoretical and algorithmic approach of modelling non-linear, variable elastohydrodynamical problems still remains Herculean, warranting interest into rehabilitation theory aiming caffeine essential present origin results.
