Support After Production: Bearing Issue Detector
Is your application not operating like it should?
Analyze the condition of your bearing system using our automatic, web-based bearing frequency calculator. We use bearing kinematics to help you detect issues.
Bearing Frequency Analysis
Bearings are a combination of geometric shapes rotating relative to each other. We’ve calculated frequencies, based on mathematical models, that would show up if there was damage to the rolling elements of the bearing.
Comparing frequency ranges from our calculator to your measured reading can pinpoint noise or vibration spikes that are outside the normal range.
You’ll be able to pinpoint if the bearing damage is occurring at the:
- Outer race
- Inner race
- Bearing cage
If no correlation is found then the issue could be unrelated to the bearings.

A Bearing Frequency Analysis is an Art Form
Completing numerous system-wide bearing performance analysis’s has given us a lot of experience in detecting bearing issues.
A lot of the time bearing frequencies don’t perfectly align.
Frequency spikes very close to what’s provided in this calculator could still signal a precision bearing issue. Therefore, we recommend you contact us for a system-wide bearing performance analysis.
Also, be aware of frequency spikes that are at RPM or at a harmonic of the RPM the unit is running at. This could be from an imbalance, out of roundness, out of concentric housing, tool noise, etc. Please contact our engineers for support during this time. Precision bearing failure analysis can be much smoother and faster with years of experience on your side.
Please note: The precision bearing fault frequencies come from industry accepted calculations. If there are any questions please contact GMN USA engineers for support. Also, our GMN Precision Bearing Catalog (page 92) has the formulas that we’ve outlined.
