Product Description
ISO 17357 Certified Yokohama Type Floating Pneumatic Rubber Fenders

Floating Ship Yokohama Type Marine Pneumatic Rubber Fenders are made of synthetic-cord-reinforced rubber sheets with compressed air inside to enable them to float on water and function as shock absorbers between ships (ship-to-ship) or between ships and berthing structures.

Yokohama Type Floating Pneumatic Rubber Fender in marine application

Note: These fenders are sometimes referred to as "Yokohama Fenders" or "Yokohama type fenders" and comply with ISO 17357:2014 standards for Floating Pneumatic Rubber Fenders.

Key Advantages
  • Lightweight design for easy handling and installation with guy-ropes or chains
  • Resists shearing force and maintains energy absorption under 15° inclined compression
  • Provides low, even hull pressure distribution
  • Multiple synthetic-cord layers with abrasion-resistant rubber for rough conditions
  • Minimizes maintenance costs and damage risk
  • Self-buoyant design ensures long service life
Construction Details

Pneumatic rubber marine fenders consist of outer rubber, reinforcement synthetic-tire-cord layer, and inner rubber, vulcanized firmly. Fenders ≥2500mm diameter include safety valves to release excess pressure.

Material Components

Outer Rubber: Protects cord layers with high tensile and tear resistance for severe weather conditions.

Tire Cord Layers: Reinforcement layer maintains internal air pressure integrity.

Inner Rubber: Seals pressurized air inside the fender.
