Belzonas Optimized Bearing Installation

Industry:

Marine (MRNE)

Application:

Ships and Offshore Structures (SOS)

Customer Location:

Shipbuilders in Germany and USA

Application Date:

Various since 1990

Application Situation:

Container Ship Rudder Bearings

Problem:

Conventional methods of installation result in lengthy times for machining of the housings. Corrosion can still occur if stainless steels are used.

Products:

Belzona® 1211 (E-Metal)

Belzona® 1321 (Ceramic S-Metal)

Substrate:

Carbon Steel

Application Method:

The application was carried out using a modified version of Belzona Know-How System leaflet SOS-4.

Belzona Facts:

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.
