Not all grease is created equal, and choosing the right type of grease can be a difference maker for your automated lubrication systems. Choosing the right type of grease is determined by variables such as: the operational temperature, the intended use, the severity of the conditions of use and nature (constant or constantly changing), and ambient factors as well. The primary ingredients in lubricating greases are metal soap (also called "thickener" or "soap skeleton") and oil. The oil particles give the grease it's lubricating properties while the metal soap actually holds it together. In addition to oil and soap, most grease contains additives that fight oxidation and corrosion.
So, what makes good grease? In short, there are three major functions of good grease. First, it prevents metal-to-metal contact between greased components. Secondly, it prevents the intrusion of polluting elements and moisture by forming a protective film around the greasing point. Lastly, it prevents oxidation and corrosion. That's the short answer. The longer answer to what makes good grease is that good grease must meet a handful of careful requirements. Those requirements include making sure the grease is homogenous. That means that the oil and soap should never separate, even under high pressure or long durations of time.
Additional requirements include being durable enough to withstand the temperature changes that occur as the grease is pumped throughout the system. Good grease should still be easy to pump at low temperatures. It should also be highly water resistant, and it should keep its properties in the severest of conditions. Lastly, good grease should never contain any heavy metals. Here at Mountain Regional, we are happy to advise you on which grease will provide the best results for you, and for the greasing system that you have selected.
