In marinas and yacht clubs, cylindrical boat fenders provide effective protection for smaller vessels, ensuring safe docking and minimizing damage to both the boats and the dock.
Cylindrical rubber fenders are designed to absorb and dissipate kinetic energy efficiently, reducing the impact forces on both the vessel and the dock. This minimizes the risk of structural damage and enhances safety.
Made from high-quality rubber, these fenders are resistant to UV rays, saltwater, and extreme temperatures. Their robust construction ensures long-term durability, reducing the need for frequent replacements.
The simple yet effective design of cylindrical rubber fenders makes them suitable for a wide range of marine applications. They can be easily adapted to different docking configurations and vessel types.
Cylindrical rubber fenders are easy to install and require minimal maintenance. Their straightforward design allows for quick and cost-effective installation, reducing downtime and operational costs.
While offering superior protection and durability, cylindrical rubber fenders are also cost-effective. Their long lifespan and low maintenance requirements result in significant cost savings over time.
These fenders are designed to withstand harsh marine environments, including exposure to saltwater, UV radiation, and extreme weather conditions. This ensures reliable performance in various maritime settings.
Tonly offers a wide range of cylindrical marine fenders with customizable outer diameters (OD) and inner diameters (ID) to meet specific energy absorption requirements. Below are the standard dimension ranges for our Cy-type fenders.
| Model Type | Outer Diameter (OD) mm | Inner Diameter (ID) mm | Max Length (L) mm | Standard Application |
| CY150 | 150 | 75 | 2000 | Small Boats / Marinas |
| CY300 | 300 | 150 | 3000 | Workboats / Pontoons |
| CY500 | 500 | 250 | 3000 | General Cargo Berths |
| CY800 | 800 | 400 | 3000 | Bulk Carrier Terminals |
| CY1000 | 1000 | 500 | 3000 | Oil & Gas Platforms |
| CY1500 | 1500 | 750 | 2000 | Supertanker Docks |
| Custom | Up to 2700 | Customizable | Per Request | Heavy-duty Offshore |
Note on Performance: The energy absorption and reaction force of a cylindrical fender are directly influenced by the ratio of the ID to the OD. Tonly’s engineering team uses a 60-year proprietary vulcanization process to ensure the rubber density remains uniform across these large dimensions, preventing structural fatigue.

Why Our Features Matter: The Tonly Advantage
Material Science: Our proprietary rubber compounds are the result of 60 years of R&D, optimized for energy absorption and environmental resistance.
Manufacturing Control: As a factory-direct manufacturer with in-house vulcanizing tanks (like our Cylindrical-fender Vulcanizing Tank), we control every production step, guaranteeing quality and consistency.
Engineered for Value: Every feature is purpose-driven to deliver cost-effectiveness through longevity and reduced operational hassle, not just initial price.
Installing cylindrical fenders is straightforward due to their versatile design. Depending on the dock structure and vessel type, they can be suspended using chains or mounted directly with steel bars. Follow these professional installation steps:
Preparation: Inspect the quay wall or hull surface to ensure it is clean and structurally sound. Prepare the necessary mounting hardware, typically including galvanized chains, shackles, and U-anchors.
Positioning: Determine the optimal fender height based on the lowest and highest water levels (tides) to ensure continuous protection during berthing.
Chain Attachment: Thread the heavy-duty chain through the hollow center (Inner Diameter) of the cylindrical fender.
Securing Anchors: Fix the chains to the pre-installed U-anchors on the dock or vessel using high-tensile shackles. For longer fenders, multiple suspension points may be required to prevent sagging.
Final Tensioning: Adjust the chain tension to ensure the fender sits snugly against the mounting surface while allowing enough flexibility for energy absorption under impact.
Pro Tip from Tonly: For heavy-duty applications, we recommend using a central steel bar mounting system instead of chains to provide extra longitudinal stability and reduce wear on the fender's inner bore.
Cylindrical fenders are highly favored for their simplicity and versatility. Key advantages include:
High Energy Absorption: Efficiently dissipates kinetic energy during berthing.
Low Reaction Force: Minimizes stress on both the vessel hull and dock structure.
Cost-Effectiveness: Easy to manufacture and install, providing a low total cost of ownership.
Extreme Durability: Our 60-year rubber compound formula ensures resistance to UV, saltwater, and abrasion.
Installation is flexible depending on the application. The most common method is Suspended Installation:
Thread a heavy-duty galvanized chain or steel bar through the fender's hollow center.
Attach the chain ends to U-anchors or brackets pre-fixed on the quay wall.
Secure with high-tensile shackles.
For tugboat bows, they can also be attached using longitudinal chains and peripheral ropes to ensure a snug fit against the hull.
Yes. While we offer standard outer diameters (OD) from 150mm to 2000mm, Tonly can provide custom dimensions up to 2700mm and specific lengths to meet your unique project requirements. We also offer custom rubber compounding for extreme temperature environments.
