We hope this helps you understand more about how to properly lubricate your machines and how to keep them running smoothly. Stay tuned for our next blog post, which will cover lubrication best practices such as cleanliness, overgreasing, oil sampling, and more.

Knowing the proper grease compatibility is particularly important to machine maintenance because lubricant failure can have a serious impact and price tag attached to it. Dire consequences will occur when the wrong thickeners react together. You may see a reaction that causes a separation of the base oils from the thickeners. Also, the base oil may no longer stick to the grease, causing it to ooze and run out of wherever it was applied. Other reactions from mixing greases can affect the performance characteristics of a running machine such as the load, temperature, stability, and more.

Let’s start with the basics. There are 4 types of lubricants: Oil, Grease, Penetrating Lubricants, and Dry Lubricants. The 2 most common lubricants you’ll be dealing with daily are oil and grease, however, your facility will still be using dry and penetrating lubricants. It’s important to understand when you should and should not be using these different types of lubricants.

Most grease manufacturers produce compatibility charts, but often manufacturers disagree with one another on certain thickener-type combinations. At the end of the day, compatibility testing is the best option. It will always take the base oil and elastomer into consideration, giving you the most accurate result.

A lot of times in the industry, lubricating machines is a task given to new employees because it’s thought to be a job for newer workers or apprentices.  Although lubrication is a relatively easy task to perform, it is still instrumental to have a good understanding of the different types of lubricants. Doing so will ensure that the wrong type is never used for the wrong application. This will inevitably prevent machine downtime and failure.

Penetrating Lubricant is what you’re grabbing when you have rusty jack bolts or parts with years of rust or debris on them. Penetrating lubricant is not long-lasting lubrication, it’s only use is for infiltrating tiny cracks, adding lubrication and breaking up rust.

Oil is one of the most common lubricants found in plants. It’s a thin liquid that comes in different “weights” or viscosity, the lower the weight number, the thinner the oil. At times, additives can be mixed with the oil to prevent oxidizing and corrosion.

Grease is made by mixing oil, a thickener, (usually a lithium-based soap) and at times additional lubricants, like PTFE (Teflon). Due to how it’s made, it has the same lubricating properties as oil. However, it’s texture and stickiness helps it adhere to surfaces better. Greases come in a variety of consistencies, the thinnest being similar to ketchup, the thickest coming close to a block of cheddar cheese.

Dry Lubricant is a great alternative when you can’t use oil or grease that will attract dust and dirt. At a molecular level, the tiny particles that make up dry lubricant  (like graphite) are super slippery. Dry lubricant usually comes in a spray form that’s been mixed with water, alcohol, or another solvent that eventually will evaporate away leaving behind a thin film of lubricant to reduce friction.
