Lubrication - Wikiped

Lubrication is the process or technique of using a lubricant to reduce friction and/or wear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology. Lubricants can be solids (such as Molybdenum disulfide MoS2),[1] solid/liquid dispersions (such as grease), liquids (such as oil or water), liquid ...

Lubrication Concepts - Industrial Wiki - odesie by Tech .

Basics of Lubrication. Lubrication reduces friction between moving parts by substituting fluid friction for solid friction. Without lubrication, it is difficult to move a hundred-pound weight across a rough surface; with lubrication, and with proper attention to the design of bearing surfaces, it is possible to move a million-pound load with a motor that is small enough to be held in the hand.
