After working your tractors, combines, harvesters, and your fifth-wheel semis for long hours, and in tough conditions, it’s time to give your equipment the pampering it deserves.  A little TLC for a different kind of employee, “the workers with wheels”.

Proper lubrication through greasing is one of the single most important factors in contributing to the longevity of your equipment and protecting your investment.

However, the question stands, are you using the right grease for each piece of equipment?  The thing to remember is not all things are created equally. Just like tractors (ex: Case IH vs. John Deere), the same is known when dealing with grease. When choosing a grease there are many factors to consider. We need to think about chemical compatibility and the NLGI rating. These can make for some serious frustration, and can make a final decision somewhat confusing.

The simplest method to choosing the correct grease, is to start with the application of the equipment.

What is the primary function of the area or part being greased?  Is the component in an extremely dirty or wet environment?  Does it carry a heavy load, or is it more general pin & bushing needs? Grease lubricates, but it also protects.  It acts as a barrier by preventing dirt and moisture from getting in critical areas like bearings and chains.  A heavy-load bearing application has different needs than general use.  For example, two grease products you typically see on the farm may be similar, and yet very different in their application and compatibility.

Cenex Poly-Xtreme is an excellent high temp, multi-purpose Polyurea grease.  It works well for resisting oxidation and battling wash out from the areas where it’s applied.

Cenex Blue Gard 500+ is a Lithium Complex, multipurpose grease that is a very popular choice for every day, all-purpose uses.  This formulation is flexible for most applications, but still provides protection in challenging situations.

Both of these greases will provide good lubrication, and are even similar in color, but they are incompatible due to their different chemistry’s.  Not paying close attention to grease compatibility can actually create mechanical issues that may harm your equipment.  Always ensure a new grease is chemically compatible with a grease that may still be present in the equipment prior to use.

Here is a great chart on grease compatibility.

Choosing the right grease product is essential to ensuring longevity of your precious investment.  For more information on what greases are right for your business application(s), please contact one of our trained Energy Specialists.  We will be happy to visit with you help you pick out the best grease(s) for you!
