Oil Lubrication

What is Lubrication? Lubrication is the process of reducing wear and friction by applying a film that reduces friction between two surfaces in contact. The lubricant employed could be a solid, fluid, or plastic material. […]

Dry Lubricants

What are Dry Lubricants? Dry lubricants or solid lubricants are substances that, even though they’re within the solid phase, can decrease the friction of two materials that slide against one another without the requirement of […]

Introduction to Tribology

Definition of Tribology. Tribology is the science of friction, wear, and lubrication and is truly interdisciplinary. It studies the interaction of moving surfaces and every aspect related to friction, wear, lubrication, adhesion, tribo-chemistry, etc. Tribology solutions […]

Density of Oil
Density of Oil

What is oil density? Oil density is a crucial property not only in lubricants but in all fluids. For instance, as the density of a lubricant increases, the fluid becomes thicker. This leads to an […]


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 […]
