Shaft & journal machining.
In-situ restoration of propulsion shaft journals, intermediate shafts and rudderstocks, with related coupling-face and keyway work.
Recover the surface without losing sight of the system.
Shaft and journal damage must be considered alongside the component geometry and service requirements. A clear repair scope connects the machining operation to the final acceptance checks.
Propulsion shafting
The scope covers intermediate-shaft journal repair and polishing, propulsion-shaft journal diameter restoration, and tail-shaft and stern-tube journal machining.
Stern gear and rudder systems
Rudderstock journal restoration and thrust collar and shoulder machining support work on stern gear and rudder systems.
Couplings, keyways and related faces
Related work includes shaft coupling-face milling, keyway cutting and repair, hub-bore machining, reamer-hole correction and pilot-diameter restoration.
Field and workshop options
Shaft and stern-tube components can be addressed through the field-machining scope or workshop reconditioning, according to the agreed work.
Potential scope.
- Condition and dimensional evaluation of the affected surface.
- Review of access, setup and reference geometry.
- Portable or workshop machining as agreed for the component.
- Final dimensional and surface verification within the scope.
The listed activities are a starting point for scope discussion, not a guarantee of suitability for a particular component.
What helps us evaluate the work.
- Component dimensions, material and available drawings.
- Operating application, damage history and measured condition.
- Permitted repair allowance, surface requirements and access.
