Versatile Cylindrical Fender for Ports and Quays
Product Summary
Cylindrical Fenders are a simple and versatile marine fender system that can be easily installed. Their progressive reaction makes them ideal for berths serving large and small vessels. With a wide range of available sizes up to 2700mm diameter and almost any intermediate size, Cylindrical Fenders can be closely matched to each application.
Manufactured from marine-grade NR/SBR compound, these fenders offer reliable performance in general ports, fishing harbours, inland canals, and shipyards. The design is especially suitable for multi-angle impact and large tidal variation scenarios.
Key Features
- Simple and economical design – reduces initial cost and simplifies procurement.
- Easy to install and maintain – hanging mounting saves time and labor.
- All sizes up to 2700mm diameter – matches various berth requirements.
- Thick wall resists abrasion and wear – extends service life in harsh conditions.
- Progressive load-deflection curve – ensures smooth energy absorption.
- Optional CR for oil resistance, EPDM for UV resistance – adapts to special environments.

Models and Options
Cylindrical fenders are available in a wide range of diameters up to 2700mm, with almost any intermediate size possible to suit specific project requirements. Standard material is NR/SBR; optional CR (oil resistance) and EPDM (UV resistance) are available for specialized applications.
Materials and Structure
The fender body is made from a marine-grade natural rubber (NR) / styrene-butadiene rubber (SBR) compound, with a hardness of Shore A 60~70. The cylindrical shape with thick wall construction provides excellent abrasion resistance and a progressive load-deflection curve. The structure allows for easy hanging mounting and multi-angle impact absorption.
For environments with oil exposure, CR (chloroprene rubber) is available. For high UV exposure, EPDM (ethylene propylene diene monomer) is recommended.
Applications
- Bulk cargo berths
- General cargo quays
- RoRo and ferry terminals
- Fishing and workboat berths
- Pontoons and floating structures
- Tug havens
Customization
We offer customization options including special diameters, intermediate sizes, and material selection (CR or EPDM) to meet specific project needs. Custom lengths and end configurations are available upon request.
Frequently Asked Questions
What is the rated deflection of a cylindrical fender?
The standard rated deflection is 50% of the fender's original diameter. The maximum permissible deflection is 60%.
What rubber material is used?
