Dingtai manufactures Hyundai track rollers, forged steel undercarriage components that support machine weight and guide track chain movement in excavators.
Factory-direct production provides complete OEM manufacturing services, machining, heat treatment, and assembly for global Hyundai equipment fleets and distributors.
These rollers resist premature wear and flange failure, reducing track derailment risk, unscheduled downtime, and replacement labor cost.
With over 20 years of undercarriage manufacturing and ISO9001/SGS certified processes, Dingtai delivers verified durability and traceable quality control.
We use 35MnB steel, deep quenching, and precision machining to achieve high HRC hardness and extended service life under load.
Core Selling Points
- Premium 35MnB Material — Roller shells are forged from 35MnB steel, delivering high tensile strength, impact resistance, and consistent wear performance under heavy excavator loads.
- Deep Quenching/Heat Treatment — Controlled deep quenching hardens the tread and flange to 48–55 HRC, extending service life while maintaining core toughness against shock loads.
- Global Brand Compatibility — Direct replacement for Hyundai R-series excavators and dozers, engineered to match OEM mounting dimensions, bolt patterns, and load ratings.
- 100% QC Inspection — Every roller undergoes dimensional checks, hardness testing, and seal pressure validation before shipment to eliminate premature field failures.

Technical Features
The floating seal consists of two metal rings and O-rings, maintaining constant face pressure to block abrasives and retain lubricant.
A bimetal bushing with high-lead bronze lining provides low-friction rotation and reduces shaft galling under heavy radial loads.
Deep quenching produces martensitic structure on the tread and flange, balancing surface hardness with impact-resistant core toughness during operation.
Applications
- Mining
- Quarrying
- Road Construction
- Demolition
- Earthmoving
- Port & Material Handling
Frequently Asked Questions
Q: What is your MOQ for Hyundai track rollers?
A: Minimum order quantity is typically 10 units per part number. Mixed models and sample orders are accepted for first-time quality verification.
Q: How long does production and delivery take?
A: Standard production takes 20–30 days after deposit. Stock items can ship within 7–10 days; ocean freight time depends on destination port.
Q: What is the heat treatment depth?
A: Tread hardening depth is 8–12 mm depending on part number, with surface hardness of 48–55 HRC and tough core material.
Q: What warranty do you provide?
A: We provide 12 months or 2,000 working hours against material and manufacturing defects, excluding normal wear, misuse, or improper installation.
Q: How do I match the correct part number?
A: Provide the OEM part number, machine model, serial number, or dimensional drawing. Our engineers cross-reference to the correct Dingtai replacement.
Q: Are these compatible with Hyundai OEM rollers?
A: Yes. Mounting dimensions, bolt patterns, and load ratings match Hyundai OEM specifications for direct replacement without modification.
Q: What materials are used?
A: Shells are 35MnB forged steel, shafts are 40Cr alloy steel, and sealing components use NBR O-rings with hardened steel rings.
Maintenance Guide
- Installation: Clean mounting surfaces and verify bolt torque specifications. Apply thread locking compound and tighten bolts in a diagonal sequence to prevent loosening.
- Inspection: Inspect rollers every 500 hours for oil leakage, flange wear, and shaft play. Record tread wear depth against OEM minimum limits.
- Replacement: Replace when tread wear exceeds 25%, flanges are chipped, or shaft play indicates seal failure. Always replace in matched pairs or full track sets.
