Electric Motor Bearing Lubrication

Electric motor bearing greasing requires the motor to be de energized during the procedure.

Electric motor bearing lubrication. Electric motor bearing lubrication guide when it comes to lubricating electric motor bearings grease is essential. When you re considering electric motor lubrication frequency and quantity take into account the following. Guide to electric motor bearing lubrication this will help to insure maximum protection and component life. Bearing troubles account for 50 to 65 percent of all electric motor failures and poor lubrication practices account for most of these bearing troubles.

How often your facility s electric motors should be lubricated and how much lubricant they should receive depends on several factors. The proper lubrication of electric motor bearings is essential to maintaining them in peak operating condition and ultimately in reducing unnecessary downtime. According to the u s. The primary functions of an electric motor bearing.

Combined with safety issues proper lubrication can maintain the electric motor reliability. P roper lubrication of ball and roller bearings in electric motors is essential to their health. You simply need to select the correct lubricant apply the right amount each time and do so at the required frequency. The result is reduced risk of excess grease entering the electric motor stator due to couetti flow and reduced viscosity due to heat.

In fact proper usage can keep your bearings in peak operating condition which can enhance equipment life and minimize maintenance downtime. Put simply we are killing our motors through poor lubrication practices. Guide to electric motor bearing lubrication. A grease s consistency is one of its most.

Grease lubrication grease is frequently used as an electric motor bearing lubricant because of its simplicity of application and unique characteristics. Your electric motor builder may provide a specific recommendation. 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.

Get to know the failures. So why do so many companies get it wrong. Electric motor lubrication is not complicated. Of those 53 are due to bearing failures.

The typical mineral oil viscosity in an electric motor grease is in the range of 500 to 600 sus at 100 f. Many electric motor failures are bearing related with the bearings never reaching their intended life. Motor life depends on bearing life and bearing life depends on proper lubrication. 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.

It also transfers heat from the bearing and even helps protect the bearing from dirt and contaminants. Is the lubricant grease or oil.
