Lubricants and Oils
When two moving solid surfaces interact, material from those surfaces can be lost. This loss of material is known as “wear.” Wear on equipment can shorten the lifespan of machines, disrupt production, and result in product loss. Lubrication is the process of using substances called lubricants to reduce wear. This course covers what lubricants are, what they are made of, and common types of lubricants. This course also illustrates the differences between common lubricating methods as well as safe storage and handling requirements.

Key Questions
What are lubricants designed to do?
Lubricants reduce friction between moving surfaces and reduce wear.
What are some benefits of synthetic oils?
Synthetic oils have low chemical reactivity and toxicity, high water resistance, and resistance to oxygen, ozone and ultraviolet light.
What is “viscosity”?
Viscosity refers to the ability of a liquid to flow. To perform properly, lubricants must have a viscosity low enough to penetrate the small spaces between moving surfaces and high enough to separate them.
What are the main types of industrial lubricants?
The main types of lubricants are gear lubricants, hydraulic oils, compressor oils, and cutting oils.
What is oil analysis?
Oil analysis consists of different types of tests designed to spot potential issues, reduce costs, and extend the life of production equipment. Oil analysis is critical to ensuring equipment runs efficiently.
Sample Video Transcript
Lubricants are substances used to reduce friction between moving surfaces resulting in a reduction of ware. Liquid lubricants can be made from various oils and additives. The three most common oils are mineral, both pure and refined. Animal and vegetable, and synthetic. Non-liquid lubricants include greases which are semi-solid substances composed of a base oil, like mineral or vegetable oil, and a thickener. The following sections will describe these in more detail.
