The right grease for the right applications
When it comes to grease applications, simpler is better. That’s why Brenntag Lubricants Northeast proudly uses the Mobil Grease Application Guide – it’s the best system we’ve found for recommending the right grease for the right applications.
The hidden costs of complexity
Complexity appears in many forms…all of which could be impacting your cost, productivity, and equipment efficiency. Not sure what we mean? Here are some common examples:
Too many greases
- Increase the risk of using the wrong grease for a particular piece of equipment
- Product mixing leads to unplanned compatibility experiments
- Too much grease can damage seals and cause excess heat
- Too little grease can cause lubricant starvation
Storage and handling
- Inefficient inventory practices drive up the cost on the shelf
- Labeling challenges are caused by multiple brands, and too many products lead to misuse
- Make purchasing processes inefficient and complicated
- Conflicting product and use recommendations cause unnecessary confusion
Eliminating complexity from each of these categories can reduce downtime and increase productivity. But that’s not all. In order to fire on all cylinders (we had to say it), you also need to consider where the grease will be used. Check it out:
Electric motors are found in almost every industry. Because motors operate at higher speeds (1800-3600rpm) than other equipment, they tend to need lighter oil viscosities and higher thickener content, or NLGI grade, to stay in place. As a result, electric motors and other high-speed fan and pump bearings may require a different grease than the rest of your equipment.
A large portion of the equipment in most facilities tends to have similar operating conditions (range of speeds, temperatures, environmental factors). A general-purpose grease usually can be selected to have the properties to safely protect this variety of applications.
Low speed/no rotation
In low-speed conditions, where oil viscosity alone cannot separate metal surfaces, greases may need additional wear-preventing additives to protect all components. A common example of this is molybdenum disulphide (moly).
Some applications may have unique requirements that don’t fit within the above categories. Examples of these would be grease-lubricated couplings, equipment operating in environments above 180oF, or food-production equipment requiring NSF H-1-certified food-grade grease. If needed, greases for these purposes should also be discussed during Lubrication Assessment.
