Solids Handling Machinery (SHM)

 
 

Customer Location:

Hydro power station, Sweden

 
 

Application Date:

November 2008

 
 

Application Situation:

Replacement of one of the main turbine bearings.

 
 

Problem:

The original bearing was worn out and in need of replacement. The client was looking for effective solution to bond the bearing in place.

 
 

Products:

Belzona® 1321 (Ceramic S Metal)

 

Substrate:

Cast iron

 
 

Application Method:

Application was carried out using a modified version of Belzona Know-How System Leaflet SHM-7. After grit blasting the bearing housing, Belzona® 1321 was applied to the bearing housing and Thordon SXL bearing before clamping into place until cured. Finally, the bearing was machined down to the correct inner diameter.

The Belzona® 1321 was chosen as adhesive based on its excellent adhesion, electrical insulation properties and its total corrosion resistance even in harsh environments. Belzona® 1321 is a well established method for bonding Thordon bearings and this technique has been reviewed and approved by the customer who are very pleased with the results.
