Integer multiples of the running speed (e.g., 2X, 3X), typically indicating mechanical issues like misalignment or unbalance.
Misalignment happens when the shaft centerlines of two coupled machines are not concentric.
The primary rotational frequency of the machine shaft. If a motor turns at 1,750 RPM, the 1X frequency is 1,750 CPM (29.16 Hz). All fault diagnoses are relative to this baseline. 2. Core Diagnostics: The Fault Identification Matrix
This comprehensive guide explores how to effectively utilize a vibration analysis wall chart, breaks down the core fault frequencies you must monitor, and explains how to integrate this tool into your daily reliability workflow. 1.

Caused by base/frame weakness. Shows a strong 1x RPM peak.
Consider these trusted resources for your diagnostic wall charts: Integer multiples of the running speed (e
Unbalance occurs when the mass centerline of a rotating element does not coincide with its geometric centerline. Dominant 1x RPM (running speed) peak. Phase: Radial phase is steady; a 90∘90 raised to the composed with power shift exists between horizontal and vertical measurements. Direction: Predominantly radial (horizontal and vertical). Misalignment
Compare your live data spectrum to the illustrations on the wall chart.
Clear, distinct peaks appear at exact BPFO, BPFI, BSF, or FTF harmonics. If a motor turns at 1,750 RPM, the
