Dingtai manufactures Hyundai track link assemblies, the load-bearing chain components that connect track shoes and transmit drive force through the undercarriage system.
We operate as a factory-direct supplier with full OEM manufacturing services, supporting global distributors, dealers, and end users with consistent specifications.
These assemblies resist elongation and pin/bushing wear, reducing unplanned downtime and preventing premature undercarriage failure in high-impact operating conditions.
With over 20 years of manufacturing experience and ISO9001/SGS certified processes, Dingtai delivers repeatable quality for demanding heavy machinery applications.
We use 35MnB alloy steel and deep induction hardening to achieve optimal core toughness and a hardened surface for extended track link life.
Core Selling Points
- Premium 35MnB Material: Forged from 35MnB alloy steel, these links provide high tensile strength and resist bending, cracking, and impact fatigue under heavy loads.
- Deep Quenching/Heat Treatment: Deep induction hardening achieves HRC 48-56 on wear surfaces, maintaining a tough core that withstands shock loads without brittle failure.
- Global Brand Compatibility: Our Hyundai track link assemblies match OEM pin and bushing dimensions, ensuring direct replacement across R-series excavators without modification.
- 100% QC Inspection: Each batch receives dimensional checks, hardness testing, and full visual inspection before release, ensuring consistent quality and minimal field defects.

Delivery & Logistics
We ship from Quanzhou/Xiamen ports with factory-direct pricing. Standard and custom Hyundai track link assemblies are supported with flexible MOQ for trial orders.
Technical Features
Track links are forged from 35MnB and induction hardened to HRC 48–56. This balances surface wear resistance with core toughness under shock loads.
Pin and bushing bores are precision machined to tight press-fit tolerances, preventing joint looseness and maintaining pitch stability during heavy operation.
Available in sealed and lubricated configurations, the track link assembly retains oil at the pin-bushing interface, reducing internal wear and extending service intervals.
Applications
- Mining: Prolonged abrasive wear and heavy impact loads.
- Road Construction: Continuous grading and trenching operations.
- Quarrying: Hard rock excavation and high-stress undercarriage work.
- Demolition: Frequent reversing and debris impact resistance.
- Forestry: Rough terrain operation and long-distance tracking.
Frequently Asked Questions (FAQ)
What is the minimum order quantity for Hyundai track link assemblies?
MOQ is one complete track chain set for standard Hyundai models. Mixed-model trial orders are accepted for first-time buyers.
How long is delivery time?
Standard Hyundai track link assemblies ship in 15–25 days. Custom dimensions or large volume orders require 30–45 days.
What is the heat treatment depth?
Induction hardening depth is 4–8 mm depending on link section, with surface hardness controlled at HRC 48–56.
What warranty do you provide?
We provide a 12-month or 2,000-working-hour warranty against material and manufacturing defects under normal operating conditions.
Can you match Hyundai OEM part numbers?
Yes. Supply your Hyundai part number or drawing, and we will cross-reference and manufacture to OEM specifications.
Are these track link assemblies sealed and lubricated?
Yes. Sealed and lubricated (SALT) versions are available for most Hyundai R-series excavators, along with dry joint options.
Maintenance Guide
- Inspect link rail height, pin/bushing wear, and track shoe bolt torque every 250 operating hours.
- Replace track link assemblies when pitch elongation exceeds 3% or link rail wear exceeds 20% of original height.
- Use hydraulic press tooling for pin and bushing installation; never weld on load-bearing link sections.
- Maintain proper track tension and clean debris from undercarriage to prevent accelerated link wear.
