Dingtai manufactures complete Hyundai bulldozer track chain assemblies—links, pins, bushings, bolts—built to transmit drive force and support crawler undercarriage weight.
We operate factory-direct from Quanzhou, supplying OEM and aftermarket track chain assemblies to distributors and construction fleets worldwide.
Hardened pins and bushings resist abrasive wear, reducing downtime and premature undercarriage failure in rock, clay, and sand conditions.
20+ years of undercarriage manufacturing, ISO9001/SGS-certified processes, and export-grade quality control ensure consistent batch performance.
35MnB steel, precision forging, and deep quenching deliver HRC 52–60 contact surfaces and extended service life under heavy dozing loads.
Core Selling Points
- Global Brand Compatibility: Engineered as direct replacement for Hyundai bulldozer track chain assemblies; pitch, link height, and pin/bushing dimensions match OEM drawings.
- Premium 35MnB Material: 35MnB alloy steel improves tensile strength and impact toughness, preventing link cracking under high tractive loads and shock.
- Deep Quenching/Heat Treatment: Induction hardening creates HRC 52–60 wear layers on pins and bushings, resisting abrasion and extending undercarriage service intervals.
- 100% QC Inspection: Every track chain assembly passes dimensional, hardness, and magnetic particle checks before export packing.
Product Range
Our catalog of Hyundai Bulldozer Track Chain Assembly includes various specifications, fully compatible with Hyundai bulldozers.

Technical Features
Forged 35MnB links with induction-hardened pin bosses distribute contact stress and resist bending under bulldozer tractive loads and side impacts.
Deep-quenched pins and bushings achieve HRC 52–60, reducing abrasive wear in sand, rock, and clay while retaining dimensional accuracy.
Sealed/lubricated track chain assembly maintains oil film between pin and bushing, minimizing internal wear, noise, and parasitic friction.
Applications
- Mining and quarrying
- Road construction
- Land clearing and forestry
- Demolition and site preparation
- Heavy earthmoving and grading
Frequently Asked Questions
What is the MOQ for Hyundai bulldozer track chain assemblies?
One set per part number. Mixed model trial orders are accepted to support initial quality verification.
How long is delivery time?
Standard production is 15–25 days after drawing confirmation and deposit, depending on order quantity and production schedule.
How deep is the heat treatment?
Pins and bushings receive hardened depth of 4–8 mm with HRC 52–60 after induction hardening and precision grinding.
What warranty do you provide?
We provide 12 months or 2,000 service hours against manufacturing defects under normal operating conditions.
Can you match my Hyundai part number?
Yes. Send the Hyundai part number, drawing, or old sample; we confirm fitment before production.
Are track chains sold as complete assemblies?
Yes. Complete track chain assembly includes links, pins, bushings, bolts and nuts; track shoes are quoted separately if required.
Do you support older Hyundai bulldozer models?
Yes. We use OEM drawings and retained specifications to support discontinued and slow-moving Hyundai undercarriage models.
Maintenance Guide
- Inspect pin and bushing wear every 250 hours, especially in abrasive soils and rock applications.
- Maintain correct track tension according to Hyundai service manual; over-tension accelerates pitch wear and power loss.
- Check shoe bolt and track chain bolt torque every 250 hours to prevent loosening and joint movement.
- Replace track chain assembly when pitch elongation exceeds 3% of original pitch to protect sprockets and idlers.
