| Belzona Bonds Spade Rudder Bearing On Coaster | | | Industry:Marine (MRNE) | | | Application:Ships and Offshore Structures (SOS) | | | Customer Location:Scotland, UK | | | Application Date:September 2002 | | | Application Situation:Spade rudder bearing on coastal ship. | | | Problem:Significant Galvanic Corrosion - from 3 to 7mm had occured, causing the bronze bush to be unsupported. This was a spade rudder and the forces on the bearing were great. | | | Products:Belzona® 1221 (super E Metal) Belzona® 1321 (Ceramic S Metal) | | | Substrate:Steel and Bronze | | | Application Method:Application was carried out in accordance with Belzona System Leaflet SOS-9. The top of the bearing was sealed using the Belzona® 1221, and, due to the overhang over the top of the bearing, capillaries were set in to ensure good venting during the injection process. | | | Belzona Facts:All works were carried out within one day and witnessed by the Lloyds Register Surveyor. 12 kg of Belzona® 1321 was required to secure the bearing into position, providing a 100% contact between the bearing and the housing, and compressive load bearing capability significantly above the 10N/mm2 required. | | | Photographs Description
