How to Check Bearing Vibration with Benetech GM63B Vibration Meter Malaysia
Bearings are critical components in motors, pumps, fans, blowers and many other types of rotating machinery. When bearing or machine condition begins to deteriorate, a change in vibration may be one of the warning signs noticed during maintenance inspection.
The Benetech GM63B Vibration Meter can be used for routine vibration measurements around bearing housings and rotating equipment.
For factory maintenance teams in Malaysia, the greatest value often comes from taking measurements consistently and comparing them over time rather than relying on a single reading.
Why Check Bearing Vibration?
Bearings operate continuously in many industrial machines.
Changes in vibration around a bearing location may be associated with several possible conditions, including:
Bearing deterioration
Mechanical looseness
Shaft misalignment
Rotating imbalance
Mounting problems
Changes in machine operating condition
Problems elsewhere in the rotating assembly
A vibration meter does not automatically prove that a bearing is damaged.
Instead, an unusual or increasing vibration measurement provides maintenance technicians with information that can justify further inspection.
Machines Where Bearing Vibration Can Be Checked
Bearing vibration measurements are relevant to many types of rotating machinery, including:
Electric motors
Water pumps
Industrial pumps
Fans
Blowers
Compressors
Gear-driven equipment
HVAC machinery
Production equipment
General factory machinery
The measurement approach should always be appropriate for the particular machine and maintenance procedure.
Where Should You Take the Measurement?
Whenever possible, select a suitable rigid location close to the bearing housing.
For example, on an electric motor:
Non-Drive-End Bearing → Motor → Drive-End Bearing
On a motor-pump assembly:
Motor Bearing → Coupling → Pump Bearing
The exact measurement points will depend on the equipment.
What matters for routine trending is that technicians return to the same measurement points during subsequent inspections.
Step 1 – Identify the Bearing Locations
Before measuring, understand the machine layout.
Determine:
Where the bearings are located
Which side is the drive end
Which side is the non-drive end
How the machine is coupled
Which measurement points are safely accessible
Never place yourself or the instrument near dangerous moving parts simply to obtain a reading.
Follow the site's machinery safety procedures.
Step 2 – Establish Measurement Points
Create repeatable inspection points.
For example:
B1 – Motor Drive End
B2 – Motor Non-Drive End
B3 – Pump Drive End
B4 – Pump Non-Drive End
These locations can be included in the machine's preventive maintenance record.
The next technician performing the inspection will then know where previous measurements were taken.
Step 3 – Take the Measurement with the GM63B
Use the Benetech GM63B according to the manufacturer's operating instructions.
Position the sensor correctly against the selected measurement point and maintain stable contact.
Measurement consistency matters.
If one inspection is taken at one location and the next inspection is taken somewhere completely different, comparing the two readings may provide misleading conclusions.
Step 4 – Record the Result
Do not rely on memory.
Create a simple record.
For example:
Machine ID: M-08
Component: Motor Bearing
Position: Drive End
Date: Inspection date
Operating Condition: Normal load
Vibration Reading: Recorded result
Temperature: If checked
Remarks: Normal / noise / heat / other observation
After several inspections, this information becomes a useful maintenance history.
Step 5 – Compare with the Baseline
A baseline is a reference measurement taken when the machine is known to be operating under its normal condition.
Imagine the following trend:
January → Stable
February → Stable
March → Stable
April → Slight increase
May → Further increase
This pattern deserves more attention than simply looking at the May measurement by itself.
The maintenance team can then investigate why the machine's behaviour has changed.
Does Higher Vibration Always Mean a Bad Bearing?
No.
This is an important point.
Increased vibration near a bearing does not automatically mean:
“Replace the bearing.”
The vibration may be influenced by another condition in the machine.
Possible areas requiring investigation include:
Bearing → Shaft → Alignment → Coupling → Balance → Mounting → Connected Equipment
The GM63B provides vibration measurement data. Diagnosis requires the technician to interpret that information together with the machine's operating condition and other inspection findings.
Check More Than One Bearing
Suppose a motor has two bearing locations.
If you measure only one location, you have limited information.
Measuring both sides allows comparison:
Motor NDE Bearing — Reading A
Motor DE Bearing — Reading B
For a pump assembly, you can extend this further:
Motor NDE → Motor DE → Pump DE → Pump NDE
This creates a basic vibration profile across the machine.
If one location changes significantly relative to previous measurements, maintenance personnel have a clearer area to investigate.
Combine Vibration with Temperature Inspection
Vibration and temperature can complement each other during maintenance inspections.
For example:
Normal vibration + Normal temperature
may support a normal condition assessment.
Whereas:
Increasing vibration + Increasing temperature + Abnormal noise
provides a stronger reason for further investigation.
This does not replace proper machinery diagnosis, but it can make routine inspection more systematic.
Bearing Vibration for Preventive Maintenance
One of the best uses of the GM63B is not waiting until a bearing becomes extremely noisy.
Instead, include vibration measurements in a planned inspection route.
For example:
Week/Month 1 – Establish baseline
↓
Next inspection – Record again
↓
Compare readings
↓
Identify unusual changes
↓
Inspect affected machinery
This supports a transition from purely reactive maintenance toward preventive and condition-based maintenance.
Example Factory Vibration Inspection Route
A maintenance technician could create a route such as:
Machine 01 – Main Water Pump
Machine 02 – Exhaust Fan
Machine 03 – Air Compressor Motor
Machine 04 – Cooling Tower Fan
Machine 05 – Production Line Motor
At each machine, measure predetermined bearing locations and record the results.
The same route can be repeated at scheduled intervals.
Who Can Use the Benetech GM63B?
The GM63B may be useful for:
Factory maintenance technicians
Mechanical engineers
Facility management teams
Motor service technicians
Pump maintenance contractors
HVAC maintenance companies
Industrial service contractors
Building maintenance personnel
For routine machinery checks, its portable format makes it convenient to carry between different measurement locations.
