SHAFT SUPPORTS
Marine Shaft Brackets and Struts for Propeller Shaft Support
Shaft brackets must align the bearing and shaft line while matching the hull structure and installation method. ERBA Marine coordinates selection and supply from verified shaft, bearing, angle, offset and mounting dimensions.
Final material and geometry are confirmed from the vessel or yard drawing before production.
Support aligned to the shaft line
Platform, glass-in and A-bracket arrangements for different hull and mounting methods.
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.
BRACKET TYPES
Three shaft-support routes for different hull structures.
Shaft diameter is only one input; angle, offset, bearing housing and hull attachment determine the final bracket.
Platform-Type P-Brackets
Platform-mounted brackets reviewed around mounting footprint, shaft angle, bearing housing and hull support.
- Single- or twin-screw projects
- Custom platform geometry
- Aluminium bronze or stainless routes
Glass-In P-Brackets
P-brackets for compatible laminated or glassed-in installations, adjustable during installation.
- Composite hull applications
- Height and angle adjusted during fitment
- Bearing housing matched
A-Brackets & Shaft Struts
Fabricated shaft supports coordinated to shaft line, bearing housing, hull connection and handed geometry.
- Steel, stainless, aluminium or bronze routes
- Port/starboard arrangement
- Drawing-led fabrication
ALIGNMENT-CRITICAL
Bracket geometry must reproduce the designed shaft line.
A mismatch at the hull, bearing or shaft angle can create alignment problems. Verified dimensions and structural context are essential.
Shaft and bearing
The support housing is selected around the confirmed shaft and bearing.
- Shaft diameter and angle
- Bearing outside diameter and length
- Housing fit and lubrication
Hull attachment
The bracket mounting route follows the hull material and local structure.
- Platform footprint or laminate detail
- Welded or structural connection
- Vertical drop and horizontal offset
TECHNICAL ENQUIRY CHECKLIST
What to send for a useful propulsion review.
Complete information reduces unnecessary clarification and helps ERBA Marine prepare a more accurate technical and commercial response.

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
Shaft Brackets FAQs
Practical answers for selection, replacement and project planning.
They use different hull attachment arrangements. The correct choice depends on hull material, local structure, shaft-line geometry and installation method.
Yes, when shaft-line position, bearing housing, mounting geometry and verified dimensions are available.
No. Shaft angle, offset, bearing dimensions, mounting footprint, hull structure and bracket position are also required.
Yes. Both sides must be defined by drawings or verified dimensions so the geometry and handed arrangement are coordinated correctly.
They can be included when specified. Confirm bearing type, shaft diameter, housing dimensions and required fit in the enquiry.
PROJECT-SPECIFIC ENQUIRY
Request an ERBA Marine Shaft Brackets review.
Send the strongest available technical information. ERBA Marine will review the requirement and identify any missing dimensions or interfaces before quotation.
- Attach drawings and clear photographs.
- State known dimensions and operating concerns.
- Declare class, inspection or documentation needs early.
- Final scope is confirmed in writing before supply.
