Application of Grease and Nonfluid Solid Lubrication

A. Bhatia, B.E.

The mineral and synthetic oil makes up some 95% of the total lubricants market since it is easier to handle, flows directly to the part needing lubrication and conducts heat away from the moving parts. However, the use of oil necessitates the use of an associated reservoir, sometimes together with a pump and piping, which is not always practicable.

Greases are most often used where a lubricant is required to maintain its original position in a mechanism, especially where opportunities for frequent relubrication may be limited or economically unjustifiable. This requirement may be due to the physical configuration of the mechanism, the type of motion, the type of sealing, or to the need for the lubricant to perform all or part of any sealing function in the prevention of lubricant loss or the entrance of contaminants.

This 2-hr course material is based entirely on the US Army Corps of Engineers document EM 1110-2-1424, "Lubricants and Hydraulic Fluids" and covers Chapter 5; "Grease" and Chapter 6, "Nonfluid Lubrication".

The course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
