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.קרא עוד -
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.קרא עוד -
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.קרא עוד -
a complete guide to electric motor regreasing
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.קרא עוד -
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 systemקרא עוד -
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.קרא עוד -
How and When Do I Properly Lubricate My Bearings?
Proper bearing lubrication is key to keeping your motor running correctly. Lubrication separates rolling surfaces to reduce wear, removes excess heat generated by friction, acts as a barrier to contaminants, provides corrosion inhibition, and helps retain rolling elements during assembly. More than 50% of all bearing failure is due to improper lubrication! If that’s not a good reason to pay attention to the rest of this article, I don’t know what is.קרא עוד -
How Often to Grease Motor Bearings
Since maintaining your bearings by greasing them is so important, how often should it be done? The manufacturer of the motor and the manufacturer of the bearing will have a specific recommended greasing schedule. The intervals between greasing will be specific to the motor load, run time, and ambient temperature.קרא עוד -
Rolling-element bearings design and applications
Rolling-element bearings are also called antifriction bearings, as they have lower friction and reduced lubrication requirements compared to plain bearings. Their role is to support and to guide rotating and oscillating machine elements, such as shafts, wheels or axels, and to transfer loads between the different components of an assembly.קרא עוד
