PROPULSION ACCESSORIES
Marine Propulsion Accessories for Shafts, Hubs and Propellers
Small shaft-line components still require accurate dimensions and compatible interfaces. ERBA Marine supplies accessories individually or with a larger package after confirming shaft, hub, thread, taper and mating-component data.
Metric and imperial requirements can be reviewed from a drawing, accurate dimensions or a suitable sample record.
Matched threads, tapers and locking parts
Accessory selection follows the verified shaft and propeller interfaces.
ERBA-Managed Supply
Technical clarification, quotation and supply through ERBA Marine.
Drawing-Led Review
Interfaces checked from verified project information.
Newbuild & Replacement
Support for planned projects, refits and replacement scopes.
GCC Coordination
Regional commercial and delivery coordination.
ACCESSORY RANGE
Supporting components for propellers and shaft lines.
Do not assume a thread or taper from shaft diameter alone; mating dimensions must be verified before supply.
Propeller Cone Nuts
Cone nuts matched to the propeller-end thread, shaft dimensions and hub arrangement.
- Thread and seating confirmed
- Bronze and steel routes
- Standalone or package supply
Tab Washers & Locking Parts
Washers and locking details coordinated with nut, shaft thread and retention arrangement.
- Drawing or accurate dimensions required
- Metric and imperial review
- Mating nut checked
Marine Shaft Hex Nuts
Hex nuts selected from confirmed thread, dimensions, material and mating components.
- Thread form verified
- Material confirmed
- Matching spanner can be reviewed
Installation Spanners
Purpose-matched spanners supplied where required for the specified cone or hex nut.
- Matched to confirmed nut
- Workshop or onboard use
- Supply scope stated at enquiry
Hub Tapers & Mating Details
Hub taper and keyway requirements coordinated from verified shaft and propeller drawings.
- 1:16 imperial and 1:10 metric references available
- Keyway checked
- Mating surfaces verified
SMALL PART, CRITICAL INTERFACE
Accessory accuracy protects the larger shaft-line assembly.
Incorrect thread, taper or locking geometry can delay installation. Verified measurements make the enquiry faster and safer.
What to measure
The mating component defines the accessory.
- Shaft diameter and thread
- Hub bore and taper
- Nut seating and locking arrangement
How to identify
Use the strongest available evidence rather than relying on appearance.
- Approved drawing
- Verified dimensional survey
- Clear photographs with measurements

PROJECT PROCESS
A clear route from enquiry to coordinated supply.
Custom and replacement propulsion equipment benefits from documented technical checkpoints.
PROCESS
1. Send the project data
Share vessel, machinery, dimensions, photos, drawings and required scope.
PROCESS
2. Clarify the interfaces
ERBA Marine identifies missing inputs and checks connected components.
PROCESS
3. Confirm the proposal
Configuration, materials, documentation, commercial terms and delivery are agreed.
PROCESS
4. Coordinate supply
ERBA Marine remains the customer-facing contact through the confirmed supply scope.
Important: Published examples describe available solution routes. Final dimensions, materials, tolerances, class or inspection scope, price and delivery are confirmed only in ERBA Marine’s written quotation.
FREQUENTLY ASKED QUESTIONS
Propulsion Accessories FAQs
Practical answers for selection, replacement and project planning.
Yes, when accurate dimensions, thread details and clear photographs are available. A drawing or sample-based dimensional record is preferred.
Both types can be reviewed. Final availability depends on the required thread, taper, dimensions, material and quantity.
Yes. Nuts, keys, washers and related installation items can be coordinated with the principal components when included in the enquiry.
Use existing shaft and propeller drawings or obtain a verified dimensional survey. Do not assume a taper from shaft diameter alone.
Project-specific accessories can be coordinated when a standard item is unsuitable. Final feasibility and lead time are confirmed after drawing and dimensional review.
