Misalignment happens when two coupled shafts do not share a common axis of rotation. Characteristic Diagnostic Detail 1X, 2X, and sometimes 3X running speed. Spectrum View
What do you monitor most? (e.g., pumps, fans, gearboxes) What vibration analyzer brand/software does your plant use?
: Characterized by a long string of harmonics (1X, 2X, 3X, etc.) and often a "raised floor" in the spectrum. Gear & Belt Issues Vibration Analysis Wall Chart Pdf
Misalignment happens when the centerlines of two coupled shafts are not collinear. It can be angular, offset (parallel), or a combination of both. Characterized by a high and sometimes in the axial direction. Offset Misalignment: Characterized by a dominant peak at in the radial direction, often accompanied by Phase: 180∘180 raised to the composed with power phase shift across the coupling. 3. Mechanical Looseness
Detail the differences between sensor readings.
Frequencies at exactly 1 × the shaft running speed (e.g., unbalance). : Ensures the entire reliability team uses the
Shutdown needed immediately to avoid failure. Conclusion: Making the Most of Your Wall Chart
), which is calculated by multiplying the number of teeth on the gear by the shaft rotating speed.
Ensure strong magnetic coupling. Hand-held probe tips (stingers) lose high-frequency clarity above 1,000 Hz. Spectrum View What do you monitor most

A digital or printed wall chart must feature a vibration severity matrix to help maintenance teams determine whether a machine requires immediate shutdown, scheduled maintenance, or continuous monitoring.
PDFs scale to large poster sizes ( inches) without losing text clarity.
Typical charts include several essential sections to guide an analyst through a diagnosis: Vibration Analysis Wall Chart - Full Spectrum Diagnostics
A vibration analysis diagnostic wall chart is a critical visual reference tool used by maintenance professionals to identify machinery faults by matching observed vibration frequencies with known failure patterns . While you can find a free diagnostic wall chart at VibCloud , the following "paper" outlines the technical principles and common diagnostic patterns found in these charts.
