Propeller Shafts - Deck Machinery and Hull Equipment
A marine propeller shaft transmits torque from the main engine or gearbox to the propeller through the vessel's stern tube. It is normally a project-specific forged steel or corrosion-resistant shaft designed for alignment, fatigue strength, and class requirements.
ProShipWorks provides end-to-end support to source and supply Propeller Shafts for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Common references include ISO 4566 for propeller shaft ends and IACS/classification-society rules for shaft dimensions, materials, torsional vibration, and inspection. Material traceability may be documented by EN 10204 inspection certificates when specified. |
|---|---|
| Class Approval | Propeller shafts are normally designed, manufactured, tested, and surveyed for the vessel's class, such as DNV, ABS, Lloyd's Register, Bureau Veritas, ClassNK, RINA, or KR. Approval is generally project-specific rather than a universal type approval. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify approved drawings, material certificates, shaft runout, coupling fits, propeller taper contact, bearing clearances, seal condition, and shaft-line alignment. Tighten coupling and propeller fasteners to the specified procedure and record final alignment readings. |
|---|---|
| Maintenance Tips | Monitor bearing temperature, vibration, seal leakage, lubrication condition, and stern-tube wear-down. Inspect exposed surfaces for corrosion or damage and perform dimensional checks and approved nondestructive testing during scheduled surveys. |
| Safety Notes | Isolate and lock out the propulsion system before work. Prevent shaft rotation, support heavy components with certified lifting equipment, and follow enclosed-space, hot-work, and class-approved repair procedures. |
