DH55 40 Link Greased & Sealed Track Chain Assembly
Heavy duty heat treated track chain assembly with 12-18 month warranty for excavators and heavy machinery.
High-Strength Track Chain Links
Our track link assemblies are manufactured using advanced machining centers and full-range horizontal & vertical CNC machining, performing precision turning, drilling, threading and milling processes throughout production. This strict precision machining ensures superior component quality and exact assembly dimensional accuracy, effectively maximizing service life while minimizing hourly production costs.
Each track link is made from premium forged 35MNB special steel, strengthened by professional structural optimization technology and advanced heat treatment processes. This premium material and enhanced processing deliver maximum structural strength and excellent abrasion resistance for extreme working conditions. Equipped with an integrated self-lubricating system, it significantly improves wear resistance of track chain bearings and remarkably extends overall service life, reducing maintenance frequency and unplanned downtime.
