Risk Mitigation:
By determining the normal vibration levels and frequencies of critical components under normal operating conditions, VAI can quickly detect and identify any degradation due to wear, abnormal operating conditions, and improper or incomplete maintenance. By proactively addressing these changes, VAI can help prevent irreparable machinery damage or failures.
Compliance with Industry Guidelines:
VAI’s vibration testing services aligns with established industry guidelines and best practices. By adhering to these industry ‘expectations’, we ensure your machinery or structures adhere to pertinent safety and reliability standards, enhancing overall operational integrity. We have also ‘raised the ladder’ when it comes to classifying rolling element bearing defects based on their waveform impact levels and the fact that rolling element bearings degrade at an increasing rate. We’re also working on a classification chart for bearings that are operating with ‘ball skid’ type of defect.
Before a new or rebuilt “high-dollar” machine leaves a suppliers facility, you should have it tested to verify it meets all Purchase Order and Specification requirements. This test is called an “Acceptance Test”.
Although a supplier may be able to perform an Acceptance Test, due to a conflict of interest it’s always best for your Analyst or an independent test agency to perform this testing.
Our Category IV Analysts are highly trained and qualified to perform Acceptance Testing. During an Acceptance Test, we ensure the machine is operated at specified test conditions before collecting the data. We also witness all parts of the test; we verify the supplier’s gauges and instrumentation are calibrated and that all specified test conditions (pressure, dP, temperature, load, etc.) are met.
After the test data has been analyzed, we provide a detailed report which includes all test data, photos (as allowed), the test results, conclusions and recommendations.
To schedule VAI to perform an “Acceptance Test” on your behalf, call us at 815-742-1793.
Upon receipt of a new/rebuilt machine, it should be first tested “uncoupled” in the ‘motor shop’ before installation. This is to confirm the motor bearings are still in good condition and no damage to internal components occurred during shipping (loading, unloading and transportation).
The uncoupled run should measure the waveform impact levels, which should not exceed 1 g’s-Pk. If they do, the bearings were likely brinelled during transportation and should be replaced prior to installing the machine in the plant.
After installing in the plant, a “Baseline Test” is performed. The machine is started and data immediately collected to ensure the levels are not excessive due to improper installation. Data is also collected while system operating conditions are adjusted to ensure the machine doesn’t have a developing issue and, after the machine has reached normal operating conditions, a final set of data is collected. This is the “Baseline” data upon which all future data is compared.
For assistance with collecting Baseline Data and troubleshooting any vibration issues, please call us at 815-742-1793.
Periodic test data is collected on a regular basis so the health of all critical, essential and high-dollar machines can be monitored over time.
Periodic testing consists of collecting route-based data on monthly basis (recommended). This frequency is recommended by the industry because rolling element bearings can progress from a ‘good’ condition to ‘bad’ in as little as 45 days. Monthly trending will catch these issues.
Route-based data collection is exceptionally easy to perform; it’s the data analysis that requires highly trained, experienced and knowledgeable Analysts.
For help with your data analysis, call us at 815-742-1793. All you have to do is collect the data.
Yes it’s THAT easy!
It happens. Everything was fine but now the vibration data shows a step increase in the machine’s vibration levels, and they are now unacceptable.
What do you do? You could disassemble the machine and check everything (the ‘shotgun’ approach) only to put it all back together and find out you still have a vibration issue. This would a good time to call us.
Our ISO Category IV Analysts can quickly analyze the data and support emergent issues just like this. To get an emergent analysis of your data, or one of our Cat. IV Analysts on their way to your plant, just call us at 815-742-1793.
Our multi-channel testing services include the ability to continuously record very high resolution waveform data on up to 16 channels and for several hours in duration. This testing can support data collection across an entire machine while the system’s operating conditions (temperature, pressure, load and rpm) are varied.
One example where this testing would be useful, would be in placing several sensors evenly spaced on a pump’s recirc line to determine if a resonance was present, and the location of the anti-node(s) which are points of maximum vibration amplitudes.

Our ODS testing services provide hidden insights into structural dynamics, resonant frequencies and mode shapes. This testing enables us to identify issues such as mechanical weakness, excessive flexibility, bending modes, and more.
ODS testing involves collecting data while a machine is in operation. On the other hand, Modal Analysis requires a data collector to generate the machine’s vibrations by using an ‘impact’ hammer, which can be labor intensive.
The results of these tests provide a visual 3-D animation showing how a machine moves in real time at any frequency, often revealing a weakness in the design.
For support and testing, call us at 815-742-1793.
Our Vibration Analysts can perform on-site single plane fan balancing. Balancing is usually needed when amplitudes get too high at 1x operating speed. In nearly all cases, the radial vibration levels will be noticeably higher than the axial levels.
There is no need to purchase expensive vibration test equipment or balancing software; our Vibration Analysts do everything except “turn wrenches” … due to insurance restrictions.
VAI strongly recommends against untrained staff performing balancing moves because the kinetic energy of a balance weight (if it comes off) can cause personal injury or death.
To schedule on-site single-plane balancing, call us at 815-742-1793.
VAI’s core business is analyzing machinery vibration data worldwide. To ensure accurate results, we ONLY use the Industry’s best vibration test equipment and software all made by Emerson / CSI. We strongly recommend CSI’s products but don’t take our word for it. Go to an industry industry vibration conference and ask for a “show of hands” of “who uses CSI’s products?”. The response will probably be greater than 70%.
At VAI, we ONLY recommend and sell what we use for our livelihood, and we only use the industry’s best test equipment and software made by CSI.
For clients looking for the absolute best price on the industry’s best-rated hand-held vibration test meter, we offer substantial discounts to clients who select us analyze their vibration data. And as part of our service, we provide FREE on-site Data Collector Training so that your staff can begin immediately collecting data.
Need to get caught up? Want to evaluate before buying? This may be the best option for a company who wants to try CSI’s best-rated vibration test equipment before buying. We also rent to companies who need a rental unit while their meter is being repaired and those who need to ‘catch-up’ on their data analysis.
We provide FREE loaners to clients who have us analyze the data for a minimum of 30 machine-trains a month for one (1) year. These loaners are available when client meters are being re-calibrated, repaired, or when another meter is needed just to get things “caught-up”.
