Vibration Analysis Wall Chart Pdf Jun 2026

Fundamental Train Frequency (cage defects, very low frequency).

Used to identify faults directly tied to shaft rotation, such as imbalance (typically 1x RPM) and misalignment (typically 1x, 2x, or 3x RPM).

Start by looking at the highest peak in your FFT spectrum. Is it exactly 1× RPM? Is it 2× RPM? Or is it a nonsynchronous peak like 4.9× RPM (BPFO)? The chart allows you to match this exact frequency to a potential fault category.

Note whether your sensor was placed horizontally, vertically, or axially. Misalignment, for example, often shows up strongest in the axial direction. Vibration Analysis Wall Chart Pdf

Before looking at the chart, you must know the running speed (RPM). Vibration analysis is almost always relative to the 1x running speed.

Do not rely solely on frequency. Use the phase diagrams on the chart to confirm your diagnosis before pulling machinery offline. Key Benefits of Having a Chart Handy

A vibration analysis wall chart is a standard reference tool used by maintenance professionals to diagnose machinery health through frequency spectrums and waveforms Is it exactly 1× RPM

Directly bolted heavy concrete structures.

A truly comprehensive vibration analysis wall chart PDF will also incorporate internationally recognized severity standards. The most prevalent of these is (and its more recent iteration, ISO 20816 ). This standard provides a unified scale for evaluating machine health by measuring broadband vibration velocity (in mm/s RMS).

) : Always determine the exact rotation speed of the machine in RPM or Hz. The chart allows you to match this exact

phase shift across the coupling in the axial or radial direction.

Vibration analysis is the cornerstone of predictive maintenance (PdM). For machinery diagnostics professionals, reliability engineers, and maintenance technicians, interpreting complex vibration data quickly and accurately is essential to preventing catastrophic equipment failures.

Which do you currently use (e.g., Emerson, SKF, Fluke)?

Patterns appearing below the running speed, often indicating belt issues or oil whirl in sleeve bearings. Common Machinery Fault Patterns Free Vibration Analysis Diagnostic Chart - VibCloud

It allowed Sarah to quickly zero-in on specific faults like misalignment, bearing defects, or imbalance. Visual Communication: It provided a non-technical visual to explain to management a working machine needed to be stopped. Proactive Maintenance:
