Belzona® Extends The Life Of This Trunion End Bearing

 
 

Industry:

Pulp & Paper (PLPR)

 
 

Application:

Mechanical Power Transmission (MPT)

 
 

Customer Location:

Pulp Mill in Alberta, Canada

 
 

Application Date:

1996

 
 

Application Situation:

Trunion end bearing for a 40-ton lime kiln.

 
 

Problem:

The lubrication system failed on the trunion end bearing on a 4-ton lime kiln, wearing through the entire bronze liner and into the cast iron pillow block.

 
 

Products:

Belzona® 1111 (Super Metal)

 

Substrate:

Cast Iron

 
 

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet MPT-7. Side shields, C-clamps and infrared lights were used to speed up the cure time.

 
 

Belzona Facts:

The cost of a new cast iron trunion is approximately $20,000. Replacement of a new trunion was considered, but weeks of procurement time eliminated that possibility because the lime kiln was shut down. The pro-file was restored by using Belzona® 1111 (Super Metal).
