Application Situation
Customer had damaged the bearing surface and was looking for a cost effective long term affordable repair.
Application Method
The application was carriedout using a modified version of Belzona Know-How System Leaflet MPT-2. The Belzona® 1321 was injected into a mold that had been treated with Belzona® 9411 (Relaease agent) after the Belzona® 1221 had been used to seal all the open areas to contain the injected material within the repair area.
Belzona Facts
The alternative option to Belzona was to have a machine shop come in and weld up the area and then machine it back down. The heat involved was a major concern. Estimated cost was $50,000 for this repair. The Belzona repair was 1/10th of the cost and completed within a few hours.
