Understanding Types of Lubricants: Base Oil Groups

There are several key homes that decide the overall performance of lubricants. From the lubrication theory perspective, viscosity and density of a lubricant are the most crucial parameters.


Viscosity is the factor that determines the thickness of a lubricant film, that separates the surfaces (better viscosity, thicker is the film, see hydrodynamic lubrication for an example of an equation). Based on the film thickness and the blended roughnesses of the surfaces, the lubrication regime is generally determined and for this reason the level of friction. It need to be also observed, that viscosity characterizes the inner friction of the lubricant and therefore, if the viscosity is too high, the lubricant friction itself will become high and consequently the advantage of using a lubricant can be small.


Machinery and mechanical device of every type require lubrication to defend their components from the destructive consequences of friction. These lubricants are tailored to the task that wishes doing and as such, there are numerous kinds.


Using the wrong product can harm your machinery and probably void your warranty, so it’s true to recognise whilst to use grease and while use oils for lubrication. To assist you realize which lubricant is proper in your business, Crown Oil has put together this guide to provide an explanation for the numerous components of greases and lubricants which you need to know.


While there are numerous similarities among them, lubricating grease and lubricating oil are each a distinctive type of lubricant. And despite the fact that lubricants come as water-based, mineral oil-based totally (ie deriving from crude oil) and artificial-based lubricants, at Crown Oil we supply mineral oil-based totally lubricants and greases, so we’ll recognition on those.


Lubricating oils

Like the name indicates, mineral oil and grease and lubricants have comparable structures, namely:


A base oil with proper all-round lubricating homes

Additives precise to the oil’s function

The additives permit the lubricating oil to have properties that will enable the lubricant to function inside the unique environment it’ll be put to paintings in. Among others, those houses will consist of:


Low-temperature resistance

High-temperature resistance


Water resistance
