Electric Motor Grease
Low Friction, High Protection
Overview
Proper lubrication is essential for maintaining the performance and reliability of electric motors. Bearings, a critical component of most electric motors, rely on the right grease to prevent wear, minimize friction, and ensure smooth operation. However, incorrect grease selection or application is a common cause of motor failures, leading to costly downtime and repairs. By understanding the specific lubrication needs of electric motors, you can significantly enhance their efficiency and lifespan.
Common Challenges in Electric Motor Lubrication
Incorrect Grease Selection
Using the wrong grease for electric motor applications is a major contributor to early bearing and motor failures. Electric motors require lubricants with specific characteristics to ensure proper function and protection.
- Preferred Specifications: Most electric motor applications require grease with an NLGI grade of 2 or 3, a base oil viscosity of 100-150 cSt at 40°C, and good channeling characteristics.
- Key Properties: Low oil bleed, oxidation resistance, mechanical stability, and anti-wear additives are essential.
- Thickener Options: While polyurea thickener systems are commonly preferred, aluminum complex, lithium complex, or calcium sulfonate thickeners can also be suitable.Note: the predominant thickener type of grease used in modern electric motors is a polyurea based grease. Polyurea thickeners are not compatible with other thickener types.LE’s Monolec® Extend EM Grease (1282) is an excellent product designed to outperform other polyurea thickened greases in the marketplace.
LE Solution
We offer high-performance greases specifically formulated for electric motor bearings. These greases provide the necessary characteristics to protect and enhance bearing performance. Our team can assist in identifying the best grease for your motor applications, ensuring optimal reliability and efficiency.
Incorrect Grease Application
Improper lubrication practices—such as overgreasing, undergreasing, or neglecting lubrication altogether—can lead to premature motor failures. Additionally, manually greasing motors in hard-to-reach or hazardous areas can pose safety risks and increase maintenance time.
LE Solution
As an LE consultant, we can help determine the correct lubrication amounts and intervals for your electric motors. To simplify and optimize the greasing process, we recommend Single Point Lubricators, which:
- Provide a closed-loop system to keep out contaminants.
- Automatically deliver the right amount of grease at the right time, 24/7.
- Improve safety by reducing the need for manual lubrication in unsafe or hard-to-reach areas.
- Decrease labor time and minimize motor failures.
If motor bearings are greased manually, they should always be greased with a hand operated grease gun. Do not use cordless grease guns or air operated grease pump to grease electric motor bearings.
By implementing these solutions, you can ensure consistent lubrication, extend motor life, and improve overall operational safety and efficiency

LTI, has designed and installed Automatic Lubrication Systems for the Aggregate Industry; excavators, backhoes, wheel loaders, compactors and many other applications, both large and small. Not only does the aggregate industry have hauling equipment, there are the other applications that need lubrication systems/operations, such as crushing, screening, stacking, loading, and digging. As each of our systems is custom designed, we can provide many varying configurations, depending on the size of the machine in which they are used.
Lubricants - Small Cost, Huge Returns
Lubrication Management Programs Protect Your Assets and Save You Money:
Although lubricants make up a mere 3% of the typical maintenance budget; using ineffective products, techniques and applications can have a significant impact on the lubrication-related costs that make up 40% of that budget. A Lubrication Management Program designed by the Technical Consultants at Lubrication Technologies, Inc. can help you target those areas where you see red.
- Your equipment and components will last longer, run more efficiently and more reliably, and you won’t replace equipment or components prematurely
- Your labor force will spend less time on routine lubrication-related maintenance and no time on lubricant-related equipment failures
- You’ll reduce over-all lubricant consumption as well as waste
