PRECISION MECHANICAL EXECUTION
Our specialist mechanical teams are experienced in high-consequence mechanical works where precision, planning and execution quality are critical.
-
Critical Alignment: Precision alignment of rotating equipment, drive trains, couplings, gearboxes, shafts and associated machinery using laser alignment and established engineering methodologies.
-
Heavy Bearing Rectification & Replacement: Specialist bearing inspection, removal, installation, rectification and replacement, including heavy-duty bearing arrangements and complex site-based works.
-
Shaft & Journal Rectification: Inspection, measurement and rectification of shafts, journals and critical rotating components to restore dimensional integrity and operating tolerances.
-
Gearbox & Drive Systems: Installation, inspection, overhaul and replacement of gearboxes, pinions, couplings and mechanical drive systems.
-
Equipment Overhauls: Planned and major equipment overhauls incorporating disassembly, inspection, rectification, component replacement, reassembly, alignment and commissioning.
-
On-Site Machining: Precision on-site machining and component rectification where removal of equipment is impractical or would create unacceptable production and schedule impacts.

This engineering-led approach allows WESMAR to move beyond conventional maintenance and develop practical solutions for difficult or technically constrained site conditions.
ASSET RECTIFICATION & LIFE EXTENSION
When critical equipment reaches the limits of its original operating condition, replacement is not always the only solution.
WESMAR delivers targeted mechanical rectification and asset life extension solutions designed to restore equipment integrity, improve reliability and extend operating life.
Our capabilities include:
-
Component refurbishment
-
Heavy bearing remediation
-
Shaft and journal restoration
-
Gear and pinion remediation
-
Structural and mechanical modifications
-
Alignment correction
-
Wear and damage rectification
-
Equipment upgrades
-
Replacement component installation
-
Brownfield modifications
-
Reliability improvement works
We work with clients to identify practical solutions that address the underlying mechanical issue rather than simply treating the immediate failure.
