Shaft Journal Machining

Worn or damaged shaft journals are a common challenge across marine and industrial applications. Due to the large size of components and strict operational timelines, removing and transporting shafts to a workshop is often impractical or cost-prohibitive. At YAF Engineering, we offer on-site shaft journal machining, delivering precision repairs with minimal disruption to your operation.

Typical shaft types we service include:

Tail shafts and intermediate shafts onboard vessels
Turbine rotor shafts (steam, gas, hydro)
Alternator shafts in power generation systems
Shafts used in steel, concrete, petrochemical, and manufacturing industries

Our mobile machining teams utilize high-performance tools engineered for rigidity, reliability, and high accuracy. Key features of our shaft journal machining system include:

Air-driven motors for portable power and control
Self-centering bearing supports for optimal alignment
Built-in gear systems ensuring consistent rotation and finish
Rigid structural frames capable of maintaining precision under load
Diameter machining capacity up to 900 mm

With quick deployment, fast turnaround, and adherence to OEM tolerances, YAF Engineering helps minimize costly downtime while restoring shaft functionality to class-approved standards.
