Fukushima M2703 hydraulic motor
Fukushima M2703 hydraulic motor
The Fukushima M2703 Hydraulic Motor is a heavy-duty, low-pressure vane-type hydraulic motor manufactured by Fukushima Ltd., Japan, under license from Hydraulik Brattvaag (Norway). This motor is widely installed in Brattvaag and Rolls-Royce Marine deck machinery systems, making it a proven solution for high-torque marine operations such as anchor handling and mooring.
Designed for harsh offshore and marine environments, the M2703AS delivers smooth, high torque at low speed, ensuring reliable performance in critical shipboard applications.
Fukushima M2703AS Hydraulic Motor – Technical Details
Model: M2703AS
Type: Low Pressure Hydraulic Vane Motor
Manufacturer: Fukushima Ltd., Japan
License: Hydraulik Brattvaag (Norway)
Use In: Brattvaag & Rolls-Royce Marine Systems
Motor Type: High Torque Low Speed (HTLS)
Rotation:
• BRF – Clockwise (CW)
• BLF – Counter Clockwise (CCW)
Mounting: Flange Type
Weight: Approx. 920 Kg
Construction: Heavy Duty Cast Iron / Steel
Shaft Type: Keyed / Splined

Design & Working Principle
The M2703 uses a vane-type hydraulic mechanism, where internal vanes slide within a rotor to create chambers. Hydraulic oil enters and forces rotation, producing consistent torque even at very low speeds.
This design offers:
• Smooth rotation without jerks
• High reliability in low-pressure systems
• Reduced wear compared to piston motors in similar applications
Key Features
• Heavy-duty marine-grade construction
• High starting torque for heavy loads
• Low-speed stable performance (ideal for winches)
• Designed for low-pressure hydraulic systems
• Long operational life (20+ years in many vessels)
• Compatible with legacy Brattvaag / Rolls-Royce systems
• Corrosion-resistant for seawater environments
• Easy maintenance and rebuild capability
• Flange-mounted robust installation
• Proven reliability in offshore vessels
Applications
Marine & Offshore
• Anchor windlass systems
• Mooring winches
• Deck cranes
• Hatch cover systems
• Towing winches
• Cable handling equipment
• Offshore rig equipment
Industrial
• Heavy-duty lifting systems
• Slow-speed conveyor drives
• Rotary positioning systems
Brattvaag System Application
The M2703 motor is commonly used in Brattvaag hydraulic systems, where it acts as a primary drive motor for:
• Anchor handling systems
• Mooring winch drives
• Hydraulic deck machinery
Its low-pressure design perfectly matches older Brattvaag hydraulic power packs, ensuring seamless integration and long service life.
Rolls-Royce Marine Compatibility
This motor is also found in Rolls-Royce Marine deck machinery, particularly in:
• Anchor windlass drives
• Mooring winch systems
• Offshore vessel equipment
Rolls-Royce systems often utilize similar low-pressure hydraulic architecture, making the M2703 a direct replacement or retrofit solution.
Maintenance & Spare Parts
Common Spare Parts
• Seal kits (O-rings, shaft seals)
• Vanes and springs
• Bearings
• Shaft components
• Gaskets
Maintenance Tips
• Always use clean hydraulic oil (ISO standard)
• Replace seals during overhaul
• Check vane wear periodically
• Ensure proper pressure settings (avoid overloading)
Advantages
• Reliable in extreme marine conditions
• Simple and serviceable design
• High torque at low RPM
• Ideal for legacy vessel systems
• Long lifecycle with proper maintenance
• Cost-effective compared to modern replacements
