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 Disconnect THOMAS Coupling From Induction Motor Hub?


This post I would like to share video how to disconnect or dis-engage THOMAS Coupling from motor hub during maintenance works.In this video,technician plan to replace new bearing for the motor due to abnormal sound detected from bearing.Normally in industry or chemical plant,Thomas Coupling is the one of common application to connect electric motor as a drive and pump as a rotary equipment for the process.

The main reason why Thomas coupling are used :-

  1. To transmit power from one shaft to another, efficiently and effectively.
  2. To accommodate slight shaft misalignment which develop in service.

Thomas coupling application also can protect our equipment from mechanical damage and misalignment. Below several protection when using Thomas coupling :-

1. Absorb shock, vibration and pulsations.

2. Decrease cross load on bearings.

3. Accept load reversals.

4. Minimize backlash. Read More

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 It’s Work : SMC Auto Drain Functional and Operation

This time I would like to share about Auto Drain operational to discharge automatically water inside compressed air receiver tank.This equipment is very important to remove 80% of water contain in compressed air and to ensure our compressed air is dry and clean.Why we need the clean and dry compressed air in our system?The main reason is to ensure our pneumatic equipment or instrument fully operated and pro long a life span.If water contaminated our compress air system,piping or equipment that operated with compress air will rusty,jammed and clog with dirt.It’s can cause a breakdown and it loss to our operation cost.

Below is example of SMC Auto Drain Operational to remove out water inside receiver tank.We can see a lot of water came out to drainage when auto drain operated.You can image how much water can go through inside to air supply system and can damage our equipment and pipeline.Feel free to watch the video and please share,like or comment if you think it’s benefit.

Motor Specifications – Voltage,Ampere and Frequency

These parameters are important to clarify our application design from voltage value,phases,full load ampere, overload setting and frequency setting if using Variable Speed Drive.

As an electrician,we must fully understand what is mean by voltage, ampere and frequency to ensure our application safe and working properly.

Ok…let we start our discussion and explanation about Voltage, Ampere and Frequency on Electric Motor Nameplate.


What is Rated Voltage?For simple understanding, rated voltage is manufacturer design for suitable operated voltage value with optimal performance.We can refer the motor voltage and phases on the nameplate also can decide either voltage/phases is available in our installation or not.Every country have different value of voltage.Please make sure your motor are followed standard country voltage.
