Imbalance: 1X RPM (radial)
Misalignment: 2X RPM (often high axial)
Looseness: 2X, 4X, 6X (multiple harmonics)
Rolling Element Bearing faults: BPFI, BPFO, BSF, FTF (non-synchronous peaks)
Gearmesh: GMF with sidebands at RPM

You can email the file to your entire maintenance team, ensuring everyone is using the same diagnostic standard. Vibration Analysis Wall Chart Pdf

Don’t print it on 8.5”x11” letter paper (the font size for BPFO numbers will be microscopic).
Do send the PDF to a blueprint shop (e.g., FedEx Office, Staples) and print at 24” x 36” (Arch D) or larger.
Do laminate it with UV-resistant laminate, especially if mounting in a maintenance bay with solvent or oil mist.

Imbalance — dominant 1× running speed peak, synchronous phase change with load.
Misalignment — strong 1× plus 2× components, increased axial vibration.
Bent shaft — varying 1× with load/position, harmonic content.
Looseness/structural resonance — high broadband noise, harmonic series, sidebands.
Bearing defects — characteristic fault frequencies (BPFO, BPFI, BSF, FTF) and envelope detection signatures.
Gear mesh faults — mesh frequency (GMF) and sidebands at mesh ± shaft orders, modulation patterns.
Electrical faults (motor) — air-gap eccentricity, electrical noise, harmonics tied to supply frequency.
Rubs — broadband with discrete harmonics and non-linear phenomena.

—often available as a convenient PDF—becomes an indispensable tool for every reliability engineer and technician. What is a Vibration Analysis Wall Chart? You can copy, paste, and add your specific link or CTA
