Electric Motor Bearing Lubrication

Electric motor bearing lubrication guide when it comes to lubricating electric motor bearings grease is essential.

Electric motor bearing lubrication. When you re considering electric motor lubrication frequency and quantity take into account the following. Put simply we are killing our motors through poor lubrication practices. Your electric motor builder may provide a specific recommendation. Department of energy more than 70 percent of electricity consumed in industry comes from the use of electric motors which make up 25.

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. Electric motor lubrication is not complicated. So why do so many companies get it wrong. Many electric motor failures are bearing related with the bearings never reaching their intended life.

Combined with safety issues proper lubrication can maintain the electric motor reliability. It also transfers heat from the bearing and even helps protect the bearing from dirt and contaminants. You simply need to select the correct lubricant apply the right amount each time and do so at the required frequency. Is the lubricant grease or oil.

Of bearing and motor manufacturers from around the world to provide you with a guide to the proper lubrication of electric motor bearings. Get to know the failures. According to the u s. Guide to electric motor bearing lubrication.

Of those 53 are due to bearing failures. The result is reduced risk of excess grease entering the electric motor stator due to couetti flow and reduced viscosity due to heat. Bearing troubles account for 50 to 65 percent of all electric motor failures and poor lubrication practices account for most of these bearing troubles. P roper lubrication of ball and roller bearings in electric motors is essential to their health.

The primary functions of an electric motor bearing. The proper lubrication of electric motor bearings is essential to maintaining them in peak operating condition and ultimately in reducing unnecessary downtime. In fact proper usage can keep your bearings in peak operating condition which can enhance equipment life and minimize maintenance downtime. Motor life depends on bearing life and bearing life depends on proper lubrication.

Grease reduces friction and protects the surface finish from rust during long idle periods and in unfavorable environmental conditions. The typical mineral oil viscosity in an electric motor grease is in the range of 500 to 600 sus at 100 f. Grease lubrication grease is frequently used as an electric motor bearing lubricant because of its simplicity of application and unique characteristics. Proper maintenance procedures planning and the use of the correct lubricant can increase productivity by reducing these bearing troubles and motor failures.

Electric motor bearing greasing requires the motor to be de energized during the procedure. Guide to electric motor bearing lubrication this will help to insure maximum protection and component life.
