Description
The Doosan DX530LC-7 DX700LC-7 DX800LC-7 Track Link, part number 2272-7077, is a critical structural element of your heavy-duty excavator’s undercarriage system. These individual links interconnect precisely to form the continuous track chain, providing the necessary articulation for the machine to move across the most demanding terrains while supporting the track shoes (pads). The immense strength and precise fit of each track link are paramount for maintaining proper track tension, ensuring smooth ground engagement, and upholding overall machine stability during rigorous, high-load operations.
Manufactured to the most stringent OEM quality standards, this track link is crafted from ultra-high-strength, deep-hardened alloy steel. This superior material, combined with advanced multi-stage heat treatment processes, delivers exceptional resistance to the severe abrasive wear, heavy impact, and extreme bending stresses inherent in large-scale excavation applications. The precision machining of the pin and bushing bores ensures an exact, minimal-tolerance fit with corresponding undercarriage components, which significantly reduces friction, prevents premature wear, and maintains the optimal structural rigidity and flexibility throughout the entire track chain assembly. This meticulous construction contributes directly to the extended service life and unwavering reliability required for large excavators.
A worn, damaged, or fractured track link can severely compromise your excavator’s operational efficiency, leading to significant performance issues and potential safety hazards. These include inconsistent track tension, excessive noise, accelerated wear on other vital undercarriage parts (such as pins, bushings, rollers, idlers, and sprockets), potential de-tracking, and costly unscheduled downtime. Replacing critical components like the 2272-7077 track link with genuine OEM-quality parts is essential for restoring your machine’s powerful mobility, safeguarding your substantial undercarriage investment, enhancing overall operational safety, and ensuring continuous compliance with manufacturer performance and safety standards. This track link is an indispensable replacement for scheduled maintenance, track segment repairs, or comprehensive undercarriage rebuilds on your heavy-duty Doosan excavator.
