Factory Price ZHH Brand ISO Certified Pneumatic Inflatable Rubber Fender
Product Overview
Pneumatic rubber fenders, also known as Yokohama fenders, are manufactured from rubber and multiple layers of rubber-dipped tire fabric. They serve as leading anti-collision devices for marine applications worldwide.
These floating pneumatic rubber fenders are constructed from synthetic-cord-reinforced rubber sheets with compressed air inside. The internal air enables flotation on water and provides shock absorption between ships (ship-to-ship) or between ships and berthing structures during docking operations.
Key Specifications
Product Name: Pneumatic rubber fender
Product Model: cq1-1
Brand: Zhonghaihang
Diameter: 500-4500mm
Standard: ISO17357:2014
Technology: Explosion Proof, Overall Winding, Anti-Aging, Large energy absorption
Thin, soft walls with excellent contact deformation performance and high energy absorption
Superior adaptability to inclined contact up to 15 degrees
Floating capability for multi-directional ship docking applications
Easy installation and handling
Advantages at Inclined Berthing
Ships typically make initial contact with docks or other vessels at oblique angles during STS operations. Unlike solid rubber or foam fenders, inflatable rubber fenders maintain rated reaction force and energy absorption even at inclined compression up to 15 degrees.

Applications
Product Structure
Zhonghaihang Pneumatic Rubber Fenders consist of outer rubber, 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 with sufficient tensile and tear resistance strength
Reinforcement Layer: Synthetic-tire-cord layer strong enough to maintain internal air pressure
Inner Rubber: Seals pressurized air inside the fender
Safety Features: Fenders of 2500mm diameter and larger include safety valves for pressure release during accidental over-compression
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: wash, dry, fill with proper compressed air, and store in cool, dry, ventilated areas
Keep away from heat sources, acids, alkalis, oils, and greases
Do not fold or stack during storage
