High-performance pneumatic rubber fenders designed for marine vessel protection, available in diameters from 500mm to 4500mm.
Product Overview
Pneumatic rubber fenders, also known as Yokohama fenders, are manufactured using rubber and multiple layers of rubber-dipped tire fabric. These fenders serve as leading anti-collision devices for marine applications worldwide.
Floating pneumatic rubber fenders are constructed from synthetic-cord-reinforced rubber sheets with compressed air inside. The internal air enables flotation on water and functions as a shock absorber between ships (ship-to-ship) or between ships and berthing structures during docking operations.

Standard
ISO17357:2014
Technology
Explosion Proof, Overall Winding, Anti-Aging, Large energy absorption
Ships typically make initial contact with docks or other vessels during STS operations at oblique angles. Unlike solid rubber or foam fenders that experience reduced performance at inclined compression, inflatable rubber fenders maintain consistent energy absorption even at compression angles up to 15 degrees.
Vessel Tonnage Compatibility
Our pneumatic fenders are designed to accommodate various vessel sizes and tonnages, ensuring optimal protection for ships of all scales.
Applications
Pneumatic rubber fenders are suitable for various marine applications including ship-to-ship transfers, berthing operations, and port facilities.
Product Structure
Zhonghaihang Pneumatic Rubber Fenders are constructed with three primary components:
Outer Rubber: Protects cord layers and inner rubber from abrasion and external forces with superior tensile and tear resistance
Reinforcement Synthetic-Tyre-Cord Layer: Maintains internal air pressure with exceptional strength and durability
Inner Rubber Layer: Seals pressurized air inside the fender
Fenders with diameters of 2500mm and larger include safety valves to release excess internal pressure during accidental over-compression. The assembly features metal end components with dual flanges and bolt/nut clamping systems, similar to automotive tire valve structures.
Usage Precautions
Maintain fender pressure within ±5% of standard air pressure
Check air pressure every three months and adjust as needed
Avoid contact with sharp objects
When not in use for extended periods: clean, dry, inflate with proper compressed air, and store in cool, dry, ventilated areas
Store away from heat sources, acids, alkalis, oils, and greases
Do not fold or stack during storage
