Inflatable rubber fender (also called ball) is a kind of berthing buffer and protection of ship supplies, widely used in ships, offshore facilities, offshore platforms, port terminals, yachts and other fields. The inflatable rubber ball is more practical and economical than the general rubber fender, so it is widely popular.

Inflatable fender is a rubber closed container made of hanging gluon cloth as the skeleton material. The fender and ball can float on the water surface after being filled with compressed air, and it is an important buffer medium for the berthing of ships and ships and the berthing of ships and docks. At the same time, the inflatable fender can absorb the impact energy of the ship movement, reduce the recoil force of the ship, and greatly improve the safety of the ship docking.

Inflatable fender (by the ball) is based on air as the medium, the use of compressed air to absorb the impact energy, so that the ship has flexibility when docked, in order to achieve the effect of anti-collision and anti-collision. Inflatable fender (anchorage ball) has been widely used in oil tankers, container ships, engineering ships, ocean fishing boats, offshore platforms, large docks, military ports, large piers and other types of ships and offshore platforms.
