Excavator Sealed Grease-Injected Track Chains / Track Link Assemblies / Undercarriage Chains
We are committed to delivering high-quality track chains that meet OEM (Original Equipment Manufacturer) specifications.
Our complete range of track chains has been extensively validated across multiple industries, including construction, mining, forestry, quarrying, and agriculture, and is compatible with various brands and models of excavators and tracked machinery.
All components—pins, bushings, and forged link plates—are manufactured to precise tolerances to ensure joint integrity, perfect fit, and optimal sealing performance. Additionally, all parts undergo full heat treatment, with the link rail surfaces hardened via induction hardening, resulting in superior wear resistance and extended service life.
Our excavator link assemblies feature a grease-injection lubrication design combined with polyurethane seals, effectively preventing abrasive contaminants from entering the pin and bushing interfaces, enabling quiet operation and significantly enhancing wear resistance and longevity.
We also offer customized chain solutions upon request, such as heavy-duty and extended-wear-life (EWL) chains. These specialized chains incorporate larger bushings with deeper carburized layers and taller link plates, engineered for maximum durability and extended service life.
Commonly Compatible Brands and Models:
Caterpillar, Komatsu (e.g., PC2000/PC1250), Hitachi (e.g., EX1200), Daewoo, Doosan, John Deere, Kobelco, Hyundai, Liebherr, Sumitomo, Volvo, and more.
