Getting the most from this lubrication workhorse requires a solid understanding of its composition, properties and applications. G rease was first used by the Egyptians on their chariot axles more than 3000 years ago. Today, over 80% of the world’s bearings are lubricated with grease.

Grease (lubricant) - Wikiped

Grease is a semisolid lubricant.Grease generally consists of a soap emulsified with mineral or vegetable oil. The characteristic feature of greases is that they possess a high initial viscosity, which upon the application of shear, drops to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil used in the grease.
