Starvation
It is said that a contact operates under “starvation conditions” when an increase of oil supply at the contact would result in an increase of the film thickness at the contact. In other words, when […]

Types of Lubricant Additives
What Are Lubricant Additives? The additive content in lubricating oils ranges from just a few parts per million to several percentage points. Depending on the function that the additives develop they may be classed as: […]
What is Lubrication?
Lubrication can be defined as the application of some materials between two objects moving relative to each other to allow smooth operation as much as necessary. Either oil or grease is used for rolling bearings […]
Everything You Should Know About Hydraulic Fluids Before Selection
Hydraulic fluids are used for power transmission in hydraulic machinery. Hydraulic machines use fluid’s ability to perform work. So, here is some example of equipment where usually hydraulic fluids are used like excavators and backhoe Loaders, […]
Lubricant Viscosity
What is lubricant viscosity? Viscosity is the resistance of a fluid to flow. When a fluid is flowing, the molecules comprising it experience friction due to the molecular interaction among them. It means that different […]
Lubrication and fuel efficiency
Fuel Efficiency It is essential to enhance the fuel efficiency of all machines to mitigate emissions and reduce energy consumption. Automobiles and machinery rely on lubricants for optimum operation and efficient energy transfer. In all mechanical systems, lubrication […]

Elastohydrodynamic Lubrication (EHL): Theory and Definition
What is Elastohydrodynamic Lubrication (EHL)? Elastohydrodynamic Lubrication – or EHL – is a lubrication regime (a type of hydrodynamic lubrication (HL)) in which significant elastic deformation of the surfaces takes place and it considerably alters […]
Reynolds Equation – An Overview
What is Reynolds equation? Reynolds equation is a partial differential equation that describes the flow of a thin lubricant film between two surfaces. It is derived from the Navier-Stokes equations and is one of the […]
