Extending Belt Life in the Lumber Industry
A leading lumber mill replaced failing trim saw belts with Bestorq X5 EPDM Cogged V-Belts and saw belt life jump from 3–6 weeks to over 400 days.
How X5 EPDM Cogged V-Belts Increased Service Life in Lumber Mill Trim Saws
Lumber Industry Challenge – Premature V-Belt Failure on Trim Saws
A well-known manufacturer of dimensional lumber was experiencing severe wear issues with their 3/5VX800 trim saw V-belts. In the harsh, high-demand environment of their plant, belts were failing within just 3 weeks after installation. By the 4–6 week mark, multiple belts on several of the 11 saws along the line had failed—causing downtime, maintenance interruptions, and increased operating costs.

Bestorq X5 EPDM Cogged V-Belt Solution for Extreme Applications
To address the issue, the plant’s maintenance manager agreed to a trial run of Bestorq’s X5 EPDM Cogged V-Belts on two of their production lines (Lines 6 and 7).
Key features of the X5 belts included:
- Advanced EPDM compound for improved belt life
- Temperature rating of -70°F to 260°F for performance in extreme environments
- One code matching for consistent performance without matching issues
- Certified horsepower ratings equal to or better than any competitor
- Compliance with ARPM, ISO1813, and Mine Safety Standards (heat and oil resistant, static conductive)
- Backside idler compatibility without reducing belt life
Maintenance procedures included verifying proper belt tension, inspecting sheave wear, and replacing only the belts—keeping all other system components unchanged.
Proven Results – Extended V-Belt Life and Reduced Lumber Mill Downtime
The trial belts endured 15,000 start/stops per two shifts and processed over 1 million board feet per day—in what the maintenance manager described as the hardest application in the plant.
After 400+ days (58 weeks), the X5 belts were still in operation, far exceeding the performance of the previous belts.
Impact:
- Service life extended by over 13x compared to the previous belts
- Dramatic reduction in downtime and replacement costs
- Consistent production at full capacity
