Quality-conscious lubricant manufacturers provide field support to ensure products are properly selected for their customers’ machines. In the end, though, the lubricant supplier doesn’t face production losses and severe organizational stress when the machine fails. Regardless of the amount of effort provided by the supplier, the machine owner must be aware of which products were selected and whether the selections meet the demands imposed by the production process and environment.
This article addresses the nature of oil film formation and properties of fluid oil lubricants that are important to the selection process. Greases, solid film lubricants and additives will be addressed in a later article. Gases will not be addressed in this series since gases are not commonly used as lubricants for machines operating.
