Predictive Maintenance Vibration Analysis Log

Use it for rotating equipment such as motors, pumps, fans, gearboxes, compressors, and conveyors where vibration trending helps detect developing faults. It is especially useful when you already have route-based readings or condition monitoring points defined by asset tag. If an asset does not have a stable operating state or repeatable measurement point, the log will be less reliable. For one-off troubleshooting, a more detailed diagnostic worksheet may be a better fit.

The right cadence depends on criticality, duty cycle, and how quickly the asset changes under load. Many teams use weekly, monthly, or route-based intervals for stable equipment, then shorten the interval when readings trend upward or a bearing fault indicator appears. The key is consistency: take readings at the same point, direction, and operating condition whenever possible. If the machine is critical, trending should be frequent enough to support action before a failure window closes.

It should be completed by a trained maintenance technician, reliability technician, or condition-monitoring specialist who understands the asset route and measurement method. The person taking the reading should know how to verify sensor placement, operating condition, and units before recording the result. If your program uses outside contractors, they should follow the same SOP and naming conventions. The template works best when one owner is accountable for consistent data quality.

No. This log captures field readings, observations, and follow-up actions, but it does not replace a full reliability program, diagnostic software, or engineering review. It is a practical record for trend tracking and maintenance decision-making. If you need spectrum analysis, alarm logic, or automated route management, this template can still serve as the manual record behind that process. It is strongest when paired with a defined SOP and asset hierarchy.

The template includes ISO 10816 zone status so the reader can record the machine’s overall vibration condition against a recognized severity framework. That helps standardize how readings are interpreted across assets and shifts. You should still use your site’s internal thresholds, OEM guidance, and any updated program criteria where applicable. The log is a record of the observed zone status, not a substitute for engineering judgment.

The biggest issues are inconsistent measurement points, recording readings without confirming operating condition, and mixing different units or sensor types in the same route. Another common problem is writing a trend note without stating whether the change is compared to the last reading or a longer baseline. Teams also miss bearing fault indicators because they only capture overall vibration and skip the diagnostic observations. Clear setup verification prevents most of these problems.

Yes. You can rename asset fields, add route IDs, include alarm thresholds, or add a work order number if your maintenance system requires it. Many teams also add fields for RPM, load, temperature, or lubrication status when those variables affect interpretation. If you use a CMMS or EAM, this template can be aligned to your asset master and imported as a standardized inspection form. Keep the core fields intact so trend comparisons remain consistent.

The reading should trigger a review of the trend, the operating condition, and the bearing fault indicators before deciding on action. If the result is outside your site criteria or shows a clear upward trend, create a maintenance task, schedule a follow-up reading, or escalate for engineering review. Do not rely on a single reading alone unless it is clearly severe or accompanied by abnormal noise, looseness, or lubrication symptoms. The follow-up due date field helps make that next step visible.
