Lynx XD Extreme Duty Chain
Lynx XD (Extreme Duty) series chain offers approximately 25-35% higher tensile strength than standard ANSI #80 through #240 chain while maintaining dimensional compatibility with standard sprockets. The XD designation combines shot-peened side plates, harder pin steel, and tighter manufacturing tolerances to extend service life in shock-loaded and high-stress applications. Use XD chain in mining, oil & gas, steel mill, and any environment where standard chain has been failing prematurely.

Frequently Asked Questions
How is XD different from H (Heavy) series?
Both XD and H series offer higher tensile strength than standard ANSI chain. The difference: H series achieves it through thicker side plates (same pitch and pin geometry as standard); XD achieves it through shot peening, harder pin material, and tighter tolerances, same dimensional envelope as standard chain. XD chain is typically 5-10% higher tensile strength than H series, but at significantly higher cost.
Can I substitute XD for standard chain in any drive?
In most applications yes. XD chain is dimensionally interchangeable with standard ANSI chain of the same size. Same pitch, same sprocket compatibility. However, XD chain is overkill for light and moderate-duty applications where its cost premium isn't justified. Reserve XD for proven failure points in standard chain.
When should I upgrade from standard to XD?
Three triggers: (1) standard chain in your application is failing earlier than expected, typically less than 60% of design life; (2) you're commissioning new equipment in shock-load or high-stress conditions where standard chain has marginal capacity; (3) operating conditions have changed (higher loads, more cycles, harsher environment) and standard chain no longer fits.
Does XD chain require different lubrication?
No. XD chain uses the same lubricants as standard ANSI chain (typically SAE 30 or 40 oil for bath lubrication, EP-2 grease for grease applications). The shot-peened surface and harder pin material extend life under the same lubrication regime; they don't change the chemistry requirements.
