Dingtai manufactures Daewoo track link assemblies that connect track shoes and transmit drive load through the undercarriage system.
We provide factory-direct manufacturing with comprehensive OEM services, supplying replacement track link assemblies to global equipment buyers and dealers.
Our assemblies resist wear, cracking, and pitch elongation, reducing unplanned downtime and protecting sprockets from premature failure.
With over 20 years of undercarriage production experience, Dingtai holds ISO9001 and SGS certifications, ensuring repeatable quality for demanding fleets.
We use 35MnB link material and deep hardening to deliver a balanced hard surface and tough core.
Core Selling Points
- Premium 35MnB Material: Rolled and forged 35MnB steel provides high tensile strength and impact resistance for heavy loads and abrasive ground conditions.
- Deep Quenching/Heat Treatment: Induction hardening creates a hard wear surface with HRC 50–56 while preserving a ductile core to prevent brittle fracture.
- Precision Forging: Precision-forged link bodies maintain tight pitch tolerance, reducing internal friction and extending bushing and sprocket service life.
- 100% QC Inspection: Every link assembly is inspected for hardness, dimensional accuracy, and surface defects before shipment, ensuring zero-surprise installation.
Our catalog of Daewoo Track Link Assembly includes various specifications, fully compatible with Daewoo excavators and bulldozers.

Technical Features
Precision-forged 35MnB links provide high tensile strength and resist cracking under shock loads in rocky or abrasive working conditions.
Deep induction hardening creates a hard outer case on pins and bushings while retaining a tough core, maximizing wear life.
Tight machining tolerance on link pitch reduces track-shoe movement and internal friction, preventing abnormal sprocket wear.
Applications
- Mining: high-abrasion ore and overburden operations
- Road Construction: grading, trenching, and earthmoving
- Quarrying: rock loading and haul road maintenance
- Demolition: high-impact structural processing
- Forestry: rough terrain skidding and clearing
Frequently Asked Questions
What is the MOQ for Daewoo track link assemblies?
Standard stock sizes start from one complete track chain set. Custom dimensions may require a minimum order quantity depending on tooling.
What is the delivery time?
Standard assemblies ship in 15–30 days; custom OEM production normally takes 30–45 days after drawing approval.
What heat treatment depth do you use?
Pins and bushings receive deep hardening of 6–10 mm with surface hardness HRC 50–56, depending on model and undercarriage load.
What warranty policy applies?
We provide a 12-month or 1,500-hour warranty against manufacturing defects, covering material and workmanship under normal use.
Can you match Daewoo part numbers?
Yes. Send OEM part numbers or drawings, and we confirm exact-fit compatibility before production.
Are these assemblies suitable for rocky or mining conditions?
Yes. 35MnB material and deep hardening provide high impact strength and wear resistance for abrasive ground.
Maintenance Guide
- Inspect track tension weekly; excessive sag accelerates link pitch elongation and sprocket wear.
- Check pin and bushing oil leakage; replace seals before contaminants enter the joint.
- Measure pitch elongation with a gauge; replace chains before exceeding OEM wear limits.
- Clean the undercarriage frequently; packed debris increases link face and shoe bolt wear.
