Customer Reviews
I’m late in sending this, but wanted to thank Jerryborg Marine for the great job they did on the pneumatic fenders that they fabricated for me. They work perfectly and serve a long time. Very glad I found them.

—— Deepark-Dolphine Rubber

The guys over at Jerryborg Marine not only provided quick estimates, an honest timetable, and professional courtesy, but also quality work that exceeds their fair pricing. I recommend them for anyone's next project.

—— Thanh Dong-Vietnam Ecomarine

I choose Jerryborg Marine because I simply could not find any other provider that offered all the marine products I needed under one platform, such as pneumatic fenders, anchors, chains, steel wire ropes, shackles.

—— Alessandro Bitocchi-PSG AB

I have a problem with products from another vendor. The engineer of Jerryborg Marine is very enthusiastic and helps me a lot to solve the problem. I really appreciate their professional work and experts team.

What’s Marine Rubber Bumper?

 

Marine rubber bumper was first produced in 1958 by Yokohama Company of Japan, so it is also called Yokohama pneumatic fender.

                           dimensional variations of Yokohama pneumatic fender

 

Marine rubber bumper is an upgraded product of boat fender widely used worldwide, which is filled with high pressure air to withstand berthing impacts. Compared with normal elastic rubber fenders (such as waste tires, solid rubber fenders, etc.), it has high guaranteed energy absorption, low surface impact, combining high abrasion resistance with low friction and quick installation. Since its application, pneumatic rubber fender has been used as a buffer due to its high performance, and it has been widely used in ship-to-ship operation and ship-to-jetty operation.

Whats the Structure of Marine Rubber Bumper?

 

Docking bumper is made from inner rubber, synthetic-tyre-cord layer for reinforcement, outer rubber, flange opening and other metal parts.

 

The inner rubber is made from natural rubber with rubber content higher than 53%, which ensures the air retention of the pneumatic fender, and it can be used for a long time without obvious pressure relief. It is available in thickness from 2 to 4mm, which is determined according to the requirements of pneumatic rubber fenders of different specifications.

 

The synthetic-tyre-cord layer for reinforcement is gumming, and it features thick warps, competitive density and high strength. It is bonded with the inner and outer rubber after gumming, and then the three layers are bonded together after being vulcanized at high temperature. Therefore, the cord layer has high strength, abrasion and impact resistance, great thermostability, good adhesion with rubber, aging resistance and easy processing.

 

The outer rubber is mainly used to protect the reinforced layer and the inner rubber and further ensure the air retention of the docking bumper​.
