Marine Fender Roller Fenders with Wear Resistant Rubber Material for Shock Absorption and Flexible Installation

Roller Fenders are rotating marine fender assemblies designed to protect quay structures, lock walls, dry dock entrances, guide walls and other fixed marine infrastructure from vessel contact while allowing controlled longitudinal movement along the contact surface.

The system combines an elastomeric cylindrical roller with a central shaft, bearing or bushing arrangement, steel support frame and structural fixing components. Its primary engineering function is to manage vessel-to-structure interaction through a combination of rubber deformation, rotational movement and controlled load transfer.

A container terminal on the Dutch North Sea coast implemented Roller Fenders to address recurring problems at a projecting concrete corner where vessels frequently made controlled lateral corrections. The original stationary rubber fender system caused localized wear and increased friction during vessel approach maneuvers.

After installation, operators observed that vessels could continue along the berth without pronounced rubbing interaction. The rotating contact provided more predictable movement paths around the corner, and maintenance inspections showed more evenly distributed contact wear compared to the previous stationary system.

• Optimized Rubber Compound: Engineered for repeated dynamic loading with balanced hardness and elasticity, providing excellent abrasion resistance and environmental durability
• Precision Rotational Assembly: Low-resistance movement with proper shaft alignment and bearing systems for smooth rotation under operational loading
• Integrated Structural Support: Comprehensive load distribution through rubber deformation, shaft transfer, and steel frame support to host structure
• Adaptable Contact Geometry: Configurable roller diameter, length, and mounting arrangements to suit variable vessel conditions and structural requirements

• Container and General Cargo Terminals: Ideal for berth corners, guide structures, and locations with frequent vessel maneuvering and lateral movement
• Lock Gates and Inland Navigation Infrastructure: Suitable for restricted clearance environments where vessels maintain contact while progressing longitudinally
• Shipyards and Marine Repair Facilities: Effective for dry dock entrances, transfer areas, and structural corners during docking and repositioning operations

• Integrated Manufacturing: Over 30 years of experience in marine rubber products and mechanical components with coordinated production systems
• Engineering Configuration: Project-oriented approach based on actual operating conditions, vessel specifications, and structural requirements
• Quality Control: Comprehensive inspection processes for both rubber and mechanical components to ensure dimensional accuracy and performance
• Technical Support: Complete project support from specification through delivery, including installation and maintenance guidance

• Can Roller Fenders be used for vessels with different DWT ranges? Yes, the system can be designed around the actual vessel operating envelope with appropriate roller diameter, length, elevation, and spacing configurations.
• Does the rubber roller rotate freely under vessel load? Yes, when properly installed and maintained, the roller rotates around its central shaft. Regular inspection ensures continued rotational performance.
• How long can a Roller Fender remain in service? Service life depends on traffic frequency, contact energy, environmental exposure, and maintenance quality. Regular inspection determines component condition and replacement timing.
• What certifications are available? Typical documentation includes product specifications, dimensional drawings, material information, and inspection records. Project-specific requirements can be accommodated.
• What are the main maintenance points? Primary inspection areas include rubber roller surface, shaft, bearing system, supporting frame, fasteners, anchor connections, and corrosion protection.
