Are you getting the most out of your electric motors? Motor life depends on bearing life, and bearing life depends on proper lubrication.
Many electric motor failures are bearing related, with the bearings never reaching their intended life.
According to the U.S. Department of Energy, more than 70% of electricity consumed in industry comes from the use of electric motors. Further, electric motors make up 25% of all rotating equipment in a plant.
What this means to you is that maximizing your lubrication reliability efforts with electric motors can have a dramatic impact on your uptime and costs. This includes repairs, replacements, labor, and energy use.
We offer lubricants, reliability products, and expertise to help you put together a complete program to maximize the lifespan of your lubricants and electric motor bearings. This in turn will increase safety levels and reduce costs.

Incorrect Grease Selection
Selecting the right grease for electric motor applications can make all the difference in the protection and performance of bearings. Electric motors require lubricants with specific characteristics. Use of the wrong grease often leads to early electric motor failures.
The grease consistency preferred for electric motors is normally NLGI 2 or 3, with a base oil viscosity of 100-150 cSt @ 40°C. Other characteristics to look for include good channeling characteristics, low oil bleed, oxidation resistance, anti-wear additives, and mechanical stability. The preferred thickener for most electric motors is polyurea. However, aluminum complex, lithium complex or calcium sulfonate thickeners are also good options.
Incorrect Grease Application
Overgreasing, undergreasing, and not greasing at all are common problems, and all of them can lead to premature electric motor failures. Additionally, operators often have to manually grease in hard-to-reach or unsafe areas.
Your LE consultant can help determine correct lubrication amounts and intervals, then help you choose which single-point lubricator will work best in your application. These precision lubrication tools provide a closed loop system to keep out contaminants. They also take the guesswork out of maintenance by supplying the right amount of the right grease at the right time. Suitable for indoor and outdoor applications, SPLs decrease motor failures, reduce labor time, and improve safety.
It is common for a busy operator to pick up a grease gun and apply the wrong grease to the electric motor. When incompatible greases are mixed, the results can be catastrophic with severe loss of grease performance leading to bearing failure.
If manual lubrication is preferred, Clear Grease Guns are the solution for enabling the operator to see the grease before putting it in the application. When combined with a color identification and tagging system, Clear Grease Guns are part of a visual chain of custody for the maintenance operator. Consequently, this simple solution can significantly reduce human error.
