Higher Shock Load Capabilities
Kiln dryer chain application
After 7 years of use, the chain was worn out, experiencing elongation and pin failure.
Drives 81XKD with a through hardened pin
Increased fatigue resistance
Higher shock load capabilities without sacrificing wear life
Increased transverse clearances between plates, preventing stiff joints
Application Overview: 120 chain used in critical log pusher conveyor.
A wet, harsh, and dirty environment caused quick chain wearout. User was considering sealed joint chains for replacing the 120 chain, but this chain had a high cost and a long lead time.
Standard chains with hard chrome pins
Chain life at least 2X longer
Short lead time of 3-4 weeks
Cost only slightly higher than standard chain
Board edger in sawmill
The chain used on a high speed serpentine drive had a short life of only 2 months.
100-1R Extended Life CHP
Life of chain extended 3-4X
Fewer replacement costs
Debarker chain at lumber plant
The 120H-1R chain with case hardened pins had a short life. Shock load applications were causing pin breakage, and the chain needed to be replaced every 4-5 months.
120HZ-1R with through hardened pins and a press t connecting link
New hardened tooth sprockets recommended
Life of chain: over 18 months
Board planer chain in sawmill
The 140-1R chain on the planer wore out quickly, requiring replacement every month.
High quality precision roller chain
Life of chain: 3X longer
120H roller chain driving saw arbors in a timber processing machine. Saw arbors are multiple circular saws mounted on a shaft. They are used to cut cants into smaller dimensions.
Shock loads for the chain are very high, and the particles from the cut wood are extremely abrasive. Elongation happened quickly, and the chain needed to be replaced every 4 weeks.
Drives 120H standard roller chain
Quality features built into the Drives chain leads to a 12-week chain life (3X longer)
$6,500 per year
Power Transmission contract for 4 sawmills of a major lumber company. Contract was taken over recently by another distributor.
The mills had high replacement rates for roller chain.
New distributor switched to Drives USA roller chain
35% reduction in purchased roller chain units
