Belzona® Refits Crusher Bearing

 
 

Industry:

Mining and Quarrying (MINQ)

 
 

Application:

Mechanical Power Transmission (MPT)

 
 

Customer Location:

Limestone quarry, Silex, MO

 
 

Application Date:

Summer 1996

 
 

Application Situation:

New 12" dia. bearing had to be fitted to worn shaft on crusher

 
 

Problem:

Perfect fit required onto rough shaft to avoid premature failure. Previous repair with "competitor" failed.

 
 

Products:

Belzona® 1111 (Super Metal)

 

Substrate:

Steel

 
 

Application Method:

Application carried out in accordance with the Belzona Know-How System Leaflet MPT-7. The bearing was heated to 250°F. Belzona® 1111 was applied around the journal and the hot bearing quickly slid into place.

 
 

Belzona Facts:

The alternative was at least a 30 day (and lost production) wait for a new shaft during the peak season. Follow up in February 2008, the repair is still holding up.
