Precision shaft and coupling alignment on rotating equipment. Coupled assemblies aligned to OEM tolerance — reducing seal failure, coupling wear, and vibration-driven downtime — using laser instruments and certified field engineers.
Soft-foot detection and correction, base condition, pipe strain assessment, and bearing-clearance verification before any laser reading is taken. Foundation conditions determine alignment durability.
Dual-laser or projection-laser instruments measure parallel and angular misalignment to micron resolution. Live-move guidance directs shimming and lateral correction in-situ — operator sees the target in real time.
Cold-alignment targets set to compensate for thermal growth from cold start to operating temperature — so the running alignment is correct, not just the cold alignment.
Methodology runs under the broader Predictive Maintenance engagement →
Tolerances and methodology aligned to ANSI / ASA S2.75 shaft-alignment recommended practice.
Final alignment validated against the equipment OEM's published tolerance — couplings, motors, pumps, and compressors are aligned to the manufacturer's spec, not generic shop tolerances.
Delivered under the firm's ISO 9001-aligned QMS — alignment routes, soft-foot reports, and final cold/hot alignment certificates under change control.
Focus — alignment, coupling life, seal integrity.

Laser alignment is scheduled in response to specific triggers — newly installed equipment, post-overhaul commissioning, vibration findings indicating misalignment, or seal/coupling failures. Each alignment produces a per-asset certificate: pre-alignment readings, soft-foot diagnostics, corrective shimming record, and final cold/hot alignment with thermal-growth compensation. Reports land in the reliability data platform alongside the asset's vibration history.
Easy-Laser shaft- and geometric-alignment systems (XT / E-Series) for production-critical rotating equipment — including thermal-growth compensation and live-move correction.
Prüftechnik ROTALIGN family for precision shaft alignment and geometric checks on large machinery and turbomachinery, where dual-laser resolution and OEM-spec reporting are required.
