Ships and Offshore Structures (SOS)


Customer Location:

Dockyard, Bulgaria


Application Date:

June, 2010


Application Situation:

Installation of new bronze bearing in oversized bearing housing.



Corrosion damage and severe wear led to destruction of the old bearing and irregular form of the housing leading to increased annular space between the new manufactured bearing and the housing.



Belzona® 1221 (Super E-Metal)

Belzona® 1321 (Ceramic S-Metal)



Cast Iron housing & Bronze bearing


Application Method:

Application was carried out in accordance with Belzona Know-How System Leaflet SOS-9. The injection was through flexible hose placed into the four channels made in the back of the bearing.


Belzona Facts:

Belzona saved time and money against expensive machining of the housing and supply of larger bronze bush. No alternative was fast enough to compete. This standard repair procedure eliminates galvanic corrosion and provides long term location of the bearing.
