Electric Motor Bearing Lubrication

P roper lubrication of ball and roller bearings in electric motors is essential to their health.

Electric motor bearing lubrication.

Of those 53 are due to bearing failures. According to the u s. Is the bearing type sleeve ball or roller. The proper lubrication of electric motor bearings is essential to maintaining them in peak operating condition and ultimately in reducing unnecessary downtime.

Grease lubrication grease is frequently used as an electric motor bearing lubricant because of its simplicity of application and unique characteristics. Of bearing and motor manufacturers from around the world to provide you with a guide to the proper lubrication of electric motor bearings. Motor life depends on bearing life and bearing life depends on proper lubrication. Electric motor bearing lubrication guide when it comes to lubricating electric motor bearings grease is essential.

Guide to electric motor bearing lubrication. So why do so many companies get it wrong. It also transfers heat from the bearing and even helps protect the bearing from dirt and contaminants. The typical mineral oil viscosity in an electric motor grease is in the range of 500 to 600 sus at 100 f.

Is the lubricant grease or oil. Guide to electric motor bearing lubrication this will help to insure maximum protection and component life. A grease s consistency is one of its most. Your electric motor builder may provide a specific recommendation.

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. In fact proper usage can keep your bearings in peak operating condition which can enhance equipment life and minimize maintenance downtime. How often your facility s electric motors should be lubricated and how much lubricant they should receive depends on several factors. Grease reduces friction and protects the surface finish from rust during long idle periods and in unfavorable environmental conditions.

Proper maintenance procedures planning and the use of the correct lubricant can increase productivity by reducing these bearing troubles and motor failures. The result is reduced risk of excess grease entering the electric motor stator due to couetti flow and reduced viscosity due to heat. Many electric motor failures are bearing related with the bearings never reaching their intended life. The primary functions of an electric motor bearing.

When you re considering electric motor lubrication frequency and quantity take into account the following. Electric motor bearing greasing requires the motor to be de energized during the procedure. Get to know the failures. Electric motor lubrication is not complicated.

You simply need to select the correct lubricant apply the right amount each time and do so at the required frequency. Bearing troubles account for 50 to 65 percent of all electric motor failures and poor lubrication practices account for most of these bearing troubles.
