Dingtai manufactures Hyundai track groups, complete undercarriage assemblies that deliver traction, stability and weight distribution for crawler excavators.
Factory-direct manufacturing and comprehensive OEM services support global equipment distributors, rental fleets and procurement managers with reliable replacement parts.
Our track groups resist premature pin and bushing wear, preventing track elongation and unplanned downtime in high-impact earthmoving applications.
With over 20 years of experience and ISO9001/SGS certification, Dingtai delivers repeatable quality, dimensional accuracy and proven field reliability.
Premium 35MnB steel links, deep quenching and precision machining ensure high tensile strength, hardened wear surfaces and extended service life.
Core Selling Points
- Premium 35MnB Material: Track links and shoes are forged from 35MnB steel, providing high tensile strength and impact resistance under continuous heavy loads.
- Deep Quenching/Heat Treatment: Pins and bushings undergo controlled deep quenching to achieve 50-60 HRC surface hardness without brittleness or premature fatigue failure.
- Global Brand Compatibility: Precision pitch, bore alignment and machining ensure direct, secure fitment on Hyundai excavator undercarriage systems without field modification.
- 100% QC Inspection: Every Hyundai track group receives dimensional checks, hardness testing and visual inspection before packaging to ensure consistent OEM-grade quality.
Our catalog of Hyundai Track Group includes various specifications, fully compatible with Hyundai excavators and bulldozers.

Technical Features
Sealed and lubricated track groups use floating or polyurethane seals to retain internal oil and block abrasive contaminants, extending pin and bushing life.
Forged 35MnB links achieve deep hardness through controlled quenching and tempering, resisting link elongation and cracking under cyclic excavator loads.
Bushings use carburized wear layers over tougher cores, providing abrasion resistance on the sprocket contact surface without brittle fracture.
Applications
- Mining and quarrying
- Road construction and earthmoving
- Heavy civil infrastructure
- Demolition and recycling
- Forestry and land clearing
Frequently Asked Questions
1. What is the minimum order quantity for Hyundai track groups?
Standard MOQ is 2 sets per specification. Sample orders may be accepted for first-time cooperation depending on current stock availability.
2. What is the delivery time?
Standard production requires 25-35 days after drawing confirmation. Stock items can ship within 7-10 days after deposit receipt.
3. How deep is the heat treatment on pins and bushings?
Case depth is typically 3-6 mm, with surface hardness ranging 50-60 HRC depending on component size and OEM specification.
4. What is the warranty policy?
We provide a 12-month or 2,000-operating-hour warranty against material and workmanship defects under normal operating conditions.
5. Can you match Hyundai OEM part numbers?
Yes. Provide OEM part numbers or drawings, and our engineers will verify dimensions, pitch and hardness before production begins.
6. Do you supply sealed and lubricated track groups?
We offer both sealed/lubricated track groups and dry track groups based on machine model, undercarriage type and application conditions.
7. Do you provide individual track components?
Yes. We supply complete track groups and individual links, pins, bushings, shoes, bolts and nuts for Hyundai undercarriages.
Maintenance Guide
- Installation: Verify track tension and align the track group before torqueing shoe bolts to the value specified in the Hyundai service manual.
- Daily Inspection: Check for oil leaks, missing bolts and uneven shoe wear; remove debris from sprocket and idler contact areas.
- Track Tension Adjustment: Maintain the correct sag under actual ground conditions; over-tensioning accelerates pin, bushing and sprocket wear.
- Replacement Interval: Replace track groups when bushing outer diameter wear exceeds 10-15% of original diameter or link pitch is elongated.
- Bolt Re-torque: Re-torque track shoe bolts after the first 50 operating hours, then at regular 250-hour service intervals.
