Customer Location:

Application Date:



Application Situation:

Sawmill shaft.



Seized bearing on 20' shaft. Replacing the shaft would be time consuming, shutting down the entire sawmill for hours.



Belzona 1111 (Super Metal)

Belzona 9411 (Release Agent)





Application Method:

A former was made at the in-house machine shop in accordance with a modified version of Belzona Know-How System Leaflet MPT-2. Note the relief grooves down the side of the flanges. The former received two coats of Belzona 9411, then Belzona 1111 was applied. The shaft was ground and Belzona 1111 was applied. The former was bolted in place and Belzona 1111 was allowed to cure. After 2 hours, the former was removed, the excess of Belzona 1111 was dressed down with emery cloth and the new bearing installed.


Belzona Facts:

The former will be used many times as there are hundreds of shafts of the same size in the mill. The whole operation takes less than 3 hours, considerably reducing downtime versus shaft replacement.
