Our Experience

CNR has decades of experience aligning drive trains and rotating assemblies across aerospace, automotive, energy, and industrial environments.
We support test rig build and calibration, ensuring couplings, spinning components, and drive trains are precisely aligned for reliable performance.
We specialise in helicopter tail rotor drive shafts, providing bespoke alignment using our ATLAS system. Tailored to each airframe, ATLAS delivers superior accuracy,
repeatability, and operational benefits compared with traditional methods.

Laser Alignment Applications

Helicopter Shaft Lines: Tail rotor drive shafts, gearbox interfaces, couplings, and bearing supports.

Test Rigs: Transmission lines, high-speed spindles, pump/drive couplings, and instrumentation setups.

Installation & Retrofit: New machine installations, post-repair alignment, bearing changeouts, and machine moves.

Condition Improvement: Reduce vibration, temperature, and energy losses caused by misalignment.

How We Work

Survey & plan: review shaft line, couplings and supports; agree access, safety and tolerances.
Setup & measure: mount ATLAS targets/fixtures; capture offset/angle with time-stamped data.
Analyse & correct: calculate shim/move values; guide adjustments and re-measure until in tolerance.
Verify & document: final readings, photos and report; recommendations for maintenance and monitoring.
Integration (optional): interface with PLC/HMI and data capture for rigs requiring automated checks.
Handover & support: acceptance sign-off; ongoing alignment checks scheduled as required.
