JS200 Forged Idler – Heavy-Duty Track Roller for 20-Ton Class Excavators
JS200 forging idlers are precision-forged undercarriage components designed for 20-30 ton excavators operating in demanding conditions like quarrying, demolition, and hard rock excavation. Built with hot-forged alloy steel, these idlers provide superior durability compared to standard cast rollers.

Why Choose Forged Idlers?
✅ 30-50% Longer Lifespan – More resistant to wear and cracking
✅ Better Shock Absorption – Handles impact loads from uneven terrain
✅ Reduced Downtime – Fewer replacements compared to cast idlers
When to Replace?
⚠ Flange wear exceeds 30% of original thickness
⚠ Visible cracks or spalling on the rolling surface
⚠ Bearing play >1.5mm or rough rotation
⚠ Grease leakage from damaged seals
Maintenance Recommendations
Clean regularly – Remove packed mud and debris
Check every 500 hours – Inspect for abnormal wear
Replace in pairs – Ensures balanced track tension
Available Upgrades
Tungsten Carbide Coating – For extreme abrasion resistance
Extended Warranty Options – Up to 12 months coverage
