Misalignment: Unveiling the Hidden Strain on Rotating Machinery

Misalignment silently erodes mechanical health by damaging couplings, increasing energy consumption, and accelerating wear. Yet, vibration signatures from different misalignments often overlap with other faults, leading to drawn-out diagnostics and ineffective fixes. This page shows how visualizing actual machine motion removes the ambiguity from misalignment detection. See how capturing real-world movement provides precise insight into the type and severity of misalignment, supporting faster, more targeted corrective actions that restore reliability and performance.

Coupling Misalignment

Discover the definitive visual of offset misalignment, a classic challenge in rotating machinery like a motor and pump coupling. While traditional vibration analysis can hint at the problem, utilizing RDI’s camera system you can verify the misalignment without needing to stop production and pull out your other alignment tools.​

Shaft out-of-spec

When misalignment obscures root causes, traditional vibration analysis often provides only part of the picture. This video delves deeper, demonstrating how vectors that are neither in phase nor moving in the same direction definitively reveal underlying issues. By comparing horizontal versus vertical motions in an orbit plot, the undeniable out-of-phase relationship of components becomes immediately clear, highlighting the misalignment.​

Non-parallel Alignment

Angular misalignment in rotating machinery, such as between a motor and pump, often manifests as complex vibration patterns that are challenging to interpret. While conventional diagnostics might hint at issues, they struggle to reveal the definitive cause. This video illustrates how the distinct, out-of-phase motion between adjacent bearings instantly exposes angular misalignment, providing visual proof to streamline root cause analysis.​

Angular Induced vibration

When angular misalignment exists between a pump and motor, or any other coupled machinery, its subtle signature often defies traditional vibration analysis. This video clearly demonstrates how Motion Amplification makes the problem immediately apparent: observing the rotor bearing and center bearing vibrating out of phase, combined with precise vector and frequency visualization, allows for effortless identification and accurate prediction of angular misalignment, streamlining machine diagnostics.
