Bearing failures are the major cause of electric motor downtime, repair and replacement costs
Our experience in our facility along with industry research involving grease manufacturers, bearing manufacturers, motor manufacturers, our industry’s technical association, and engineering companies input can shed some light on this plight. The major problems are the type of grease, the proper application of the grease, and the frequency of application.Күбрәк укы -

Greasing Electric Motors Part 1
The lubrication of electric motors can be a critical maintenance practice for improved motor system reliability. Unfortunately, a significant amount of misinformation is provided within industry. For instance, those with a lack of knowledge of how motors and bearing work will often promote the ‘purging’ of motor grease, frequently. This practice puts undue stress on the motor, reducing its life and increasing the chance for both bearing failure and winding contamination.Күбрәк укы -
Guide to Electric Motor Bearing Lubrication
The proper lubrication of electric motor bearings is essential to maintaining them in peak operating condition and, ultimately, in reducing unnecessary downtime. This bulletin, for Applied thermal fluids customers, is intended to serve as a practical guide to the proper lubrication of electric motor bearings utilizing grease as a lubricant.Күбрәк укы -
Types of grease in motor bearings
The lesson here is to select the right grease for the application. An electric motor in an Arizona open-pit copper mine where the ambient temperature is 130 F requires different grease than an identical motor in the Arctic Circle.Күбрәк укы -
Lubrication Strategies for Electric Motor Bearings
The proprietary in-house statistics of a number of petrochemical plants in the United States indicate that approximately 60 percent of all motor difficulties originate with bearing troubles. If a bearing defect is allowed to progress to the point of failure, far more costly motor rewinding and extensive downtime will often result.Күбрәк укы -

Lastly, it’s important to choose the right lubricant—not all greases are the same and using the wrong type can lead to premature bearing failure. Ask your supplier about a grease that is specifically designed for electric motors, which is different from multipurpose extreme purpose (EP) grease.Күбрәк укы -
Develop a Preventative Maintenance Schedule
Before you proceed with greasing your motor bearings, it’s essential to create an effective preventative maintenance (PM) system. Here are some key factors to consider when setting up a PM systemКүбрәк укы -
6 Ways to Improve Electric Motor Lubrication for Better Bearing Reliability
As the “life blood” of your plant’s operation, electric motors require special lubrication considerations. The theoretical design life of an electric motor is 20 years or more. Yet many tens of thousands of industrial electric motors end up in the trash pile prematurely. This results in an enormous loss for industries across the board.Күбрәк укы
