DH55 Track link Products Details
Various types track chains with pitch of 101.6-260mm are suitable for all kinds of excava-tors,bulldozers, pavers and other crawl machineries & equipments. Specification drawings orproduct samples are welcome too.
Chain section,bushing and pin are from high quality forged steel, after special heat treatment can get high surface hardness and deep hardening layer, and also excellent wear resistance,long service life.
Key advantages
1.Premium Material Construction
Made of high‑grade 35MnB/35MnBN alloy steel; pins & bushings use 20CrMo for higher strength and better impact resistance, laying a solid foundation for stable performance in heavy-duty operations.
2.Superior Wear Resistance
Surface hardness reaches HRC 48–56 with a hardening depth of 8–15 mm; pins and bushings are processed by induction‑quenched & tempered technology, effectively enhancing abrasion resistance and extending the service life of the track link.
3.Optimized Heat Treatment
Adopts carburizing + medium‑frequency quenching process; bushings are carburized on both inner and outer surfaces (with a depth of 2.5–3 mm), achieving a perfect balance between core toughness and surface hardness, and avoiding cracks caused by uneven stress.
4.High Precision Manufacturing
All components are processed by CNC machining to ensure accurate assembly dimensions; 100% quality inspection (EQC/IPQC/FQA/OQC) is carried out throughout the production process, ensuring consistent quality and reliable performance of each track link.
5.Enhanced Durability & Crack Resistance
The tread is deeply hardened and the forging structure is reinforced, which can effectively resist cracks under heavy loads; the self‑lubricating system reduces friction between pins and bushings, further reducing wear and extending the overall service life.
6.Perfect Compatibility & Cost‑Effectiveness
It is a direct fit for Doosan/Daewoo DH55 mini excavator, fully meeting OEM standards; with competitive pricing and a 12–24 month warranty, it provides cost-saving solutions for users while ensuring product quality.
7.Reliable Performance in Harsh Conditions
It can operate stably in harsh environments such as mud, rock and mining areas, with strong adaptability; it effectively reduces equipment downtime caused by track link failure and lowers daily maintenance costs for users.
DH55 Track link Applications
Our excavator track links are versatile and suitable for various types of excavators and working scenarios.
They are perfect for construction projects, mining operations, road construction, and hydraulic engineering.
Many construction companies, mining enterprises, and excavator maintenance service providers use our track links to ensure the stable operation of their equipment.
Additionally, they are widely used in the renovation of old excavators, helping to restore the performance of the chassis system.
