Industrial-Grade Track Link Features
Precision-Machined for Long-Lasting Reliability
Eliminate premature track link failures, constant replacement delays, and escalating maintenance costs with our purpose-built track links. Engineered to deliver unshakable performance in the most demanding mining and construction environments.
Our manufacturing process utilizes advanced machining centers with horizontal and vertical CNC systems to perform comprehensive precision operations including high-accuracy turning, drilling, threading, and milling. This state-of-the-art approach ensures impeccable component quality, perfect assembly dimensional accuracy, extended service life, and reduced operational costs.
Each track link is forged from premium 35MNB special steel—renowned for its inherent toughness—then enhanced with specialized structural reinforcement technology and industry-leading heat treatment. The resulting product delivers unmatched tensile strength and superior abrasion resistance, capable of withstanding extreme loads and harsh working conditions. The integrated self-lubricating system significantly reduces friction and wear, prolonging track chain bearing service life and minimizing unplanned downtime.
