Mold Production Yokohama Type Marine Ship Factory Directly Supply ISO Certified Black Pneumatic Rubber Fenders Easy Installation

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 consist of synthetic-cord-reinforced rubber sheets with compressed air inside. The internal air enables them to float on water and function as shock absorbers between ships (ship-to-ship) or between ships and berthing structures during docking operations.

Ships typically make initial contact with docks or other vessels during STS operations at oblique angles. Unlike solid rubber or foam fenders, which experience reduced rated reaction force and energy absorption during inclined compression, inflatable rubber fenders maintain consistent performance. The energy absorption of inflatable rubber fenders remains uncompromised even at inclined compression angles up to 15 degrees.

Zhonghaihang Pneumatic Rubber Fenders are constructed with an outer rubber layer, reinforcement synthetic-tire-cord layer, and inner rubber, all firmly vulcanized together.

• Outer Rubber: Protects cord layers and inner rubber from abrasion and external forces. The rubber compound provides sufficient tensile and tear resistance to withstand weather conditions and severe usage.
• Reinforcement Layer: Synthetic-tire-cord layer strong enough to maintain internal air pressure.
• Inner Rubber: Seals pressurized air inside the fender.
• Safety Features: Fenders with diameter 2500mm and larger include safety valves to release excess internal pressure during accidental over-compression.

Fender assembly features metal ends with internal and external flanges secured by bolts and nuts, with a center valve similar to automobile tire valves. This construction ensures consistent performance under rough conditions and cyclic loads while minimizing maintenance costs and damage risks. The premium materials guarantee self-buoyancy and extended service life.

• Maintain fender pressure within standard air pressure ±5% range
• Check air pressure every three months and adjust to standard as needed
• Avoid contact with sharp objects
• For long-term storage: clean, dry, fill with appropriate compressed air, and store in cool, dry, ventilated areas
• Keep storage areas away from heat sources, acids, alkalis, oils, and greases
• Do not fold or stack fenders during storage
