Properties of Liquid Lubricants[1] | Friction, Lubrication .

The function of lubricants is to control friction and wear in a lubricating system containing machine elements such as gears and bearings. This article discusses the basic properties of lubricants to help scientists and engineers understand the principles behind lubricant selection.

Chapter 3 Lubricants - ScienceDire

Fluid lubricants are used in hydrostatic lubrication; these may be subdivided into liquid lubricants and gaseous lubricants. Liquid lubricants are more frequently employed, including water, also utilized in the first hydrostatic experiments, and liquid metals, especially sodium. But the liquid lubricants most often employed are mineral lubricants.
