STRAIN GAUGE ALIGNMENT FOR MARINE SHAFTING SYSTEMS
At ROTATEK, we deliver precision strain gauge alignment services for marine propulsion and auxiliary shafting systems. By applying strain gauges during installation, overhaul, or retrofit, we measure stress and deflection under static or simulated loads—ensuring accurate alignment before the vessel is operational.
To improve reliability, our engineers create a Finite Element Model (FEM) of the shafting to correlate real-world data with predicted stress behavior. Paired with NIST-traceable laser tracker measurements, this approach helps detect misalignment, uneven bearing loads, and structural deflection early.
Every project includes detailed reports for commissioning, QA, and long-term assurance—giving you confidence in your alignment from day one.

Unlike traditional alignment methods using a straight edges, or dial indictors, Rotatek field engineers utilize state-of-the-art 3D laser trackers for unparalleled accuracy, precision and measurement acquisition time.
What Is Strain Gauge Alignment?
Strain gauge alignment is an advanced method of verifying shaft alignment by directly measuring the strain—or deformation—experienced by shafting components under load conditions. Unlike visual or geometric alignment alone, this method provides real-world data on how the shaft system behaves when assembled and subjected to weight, misalignment, or flexural stress.
How It Works:
Strain gauges—small, highly sensitive sensors—are bonded to the shaft or surrounding components at critical locations.
As the shaft experiences mechanical stress, the strain gauges detect even the slightest deformation (measured in microstrain).
These strain readings are correlated with a Finite Element Model (FEM) to understand how alignment affects stress distribution and bearing loads across the shaft line.
When combined with laser tracker measurements, this approach allows for both geometric and structural alignment verification.
Why It Matters:
Detects unseen issues like misalignment and out of tolerance bearing loading.
Ensures shaft alignment isn’t just “within spec” but optimized for real-world conditions.
Prevents costly rework, vibration, and premature bearing or coupling failure.
Strain gauge alignment is especially valuable for marine propulsion systems, long shaft runs, and critical rotating machinery, where precise alignment under load is essential for performance and longevity.
Strain‑Gauge Alignment for Marine Shafting — FEM‑Enhanced Accuracy
When precision alignment means performance at sea, ROTATEK delivers. Our strain gauge alignment service for marine propulsion and auxiliary shafting systems combines real-world strain data with Finite Element Modeling (FEM) to validate shaft alignment under true operating conditions—before sea trials even begin.
Why It Works
Load‑verified insight: Strain gauges reveal hidden stresses and bearing loads during quiescent or simulated conditions.
FEM correlation: Our engineers build a custom FEM of your shaft line, correlating measured strains to predicted stress fields for unmatched accuracy.
Laser‑tracker precision: NIST‑traceable laser trackers capture geometry and positional data to micron‑level resolution.
What You Gain
Early detection of misalignment, uneven bearing loads, or support deflection
Reduced vibration, fuel consumption, and wear once underway
Fully documented QA package for class society and shipyard compliance
