How To Replace Bearing For Electric Motor?

With advance technology,we can found the root cause for abnormal sound using Vibration Analysis for rotating equipment.When vibration owner confirm that bearing are defected,we must plan to change or replace a bearing.This time I would like to share video completed method how to replace electric motor bearing.

This is common activities for Electrician to perform bearing replacement during daily routine or turnaround / shutdown.We must ensure all bearing condition for our electrical motor in good performance to prolong bearing life time and can avoid unplanned downtime that can increase maintenance cost.

How To Use Bearing Induction Heater ?

This post I would like to share a video How To Use Bearing Induction Heater.Normally when we dealing with bigger motor or pump bearing,it’s quite difficult to install bearing into shaft because a tolerance gap is small.If we use a bearing pusher to install bigger size bearing into shaft,it’s risky and probably percentage of bearing was damage is high.That why we must use bearing induction heater for more safe and easy bearing installation.

In this video, I used old version of SKF bearing induction heater but still working perfectly without any problem.For latest version and model of Induction Heater from SKF,please visit SKF website  Read More

How to remove bearings from equipment?

For rotating equipment normally it have a bearing for smooth running.Each type of bearing design has a deference method for remover.We must know how to remove the bearing according the types and the location it have install.

The remover process  must be done with extreme care. If not,you can damage the bearings,housings or shaft and can make the high additional cost for repairs.

Common practice for smaller bearings, we can choose  a variety of pullers available in market to deal with bearing removal process.If you not sure how to choose the right puller or need a special pullers please be obtained by contacting your electric motor supplier or manufacture for more detail. read more

Bearing lubrication

To ensure the electric motor always in good condition,we must perform periodical bearing lubrication.Normally electric motors moves the majority of rotating equipment in the industry.

From the analysis,the major cause for electric motor failure is a bearing defected around 75%.That why bearing lubrication very important to avoid electric motor breakdown.It also can save repairing cost for electric motor major failure. read more

motor nameplate information #6 – Construction

This information is very useful when we selected the electric motor.From this data we can estimate the type of motor and the suitable application to ensure it running full capacity and more efficiency.

This is a basic data that we can get from electric motor name plate.Normally it tell about enclosure,motor frame,and bearing.This information can make we easier to rectify any problem when motor is defected.

Example we can know the size and type of bearing used for that motor.We can know the information without dismantle the motor.Only from the nameplate of motor. read more

Types of bearing damage for electric motor

From research and root cause analysis for electric motor problems,the higher percentage came from bearing damage around 65%.That mean bearing is very important component in electric motor.

This time i want share about common types of bearing damage for electric motor and how to make a corrective action to avoid same problem happen again.Bearing usually can be used for a long period before their reaching the life span.

Bearing damage usually cause by improper bearing selection,no lubrication,rusty,corrosive,no greasing,wrong handling and due to types of application.Below i describe detail about types of bearing damage and how to prevent it from happen again. read more

AC Motor Nameplate

Motor name plate is the introduction or certificate for an electric induction motor.We can know in detail about an electric motor with refer to the nameplate.It same like our identification card or passport.All detail information about that electric motor we can get from this nameplate.

These parameters are then print onto the motor nameplate,it state a basic definition of what motor have received.Manufacturers often include additional information to further define a key motor features.

From motor name plate we can determine many things.All information is very useful when we perform installation,power supply termination,troubleshooting and repairing jobs. read more
