Substrate: Carbon Steel
Customer Location: Shipbuilders in Germany and USA
Application Date: Various since 1990
Belzona® 1211 (E-Metal)
Belzona® 1321 (Ceramic S-Metal)
Problem: Conventional methods of installation result in lengthy times for machining of the housings. Corrosion can still occur if stainless steels are used.

Container Ship Rudder Bearings
The application was carried out using a modified version of Belzona Know-How System leaflet SOS-4.
In this case the synthetic bearing was seated in a steel carrier ring. Bonding with Belzona® 1321 prevents the risk of crevice corrosion and fretting. On this vessel the stainless steel pintle liners are also bonded to prevent galvanic corrosion. Over 30 ships in this class have used this installation method in both Germany and the USA.
