Heavy Duty Hyundai Track Rollers – Double Flange
Dingtai manufactures the Hyundai bulldozer track roller-double flange, a critical undercarriage component that supports machine weight and guides track chain alignment.
As a factory-direct manufacturer, we provide comprehensive OEM manufacturing services for global equipment distributors, dealers, and rental fleet operators.
This roller resists severe wear and prevents premature downtime by maintaining track stability in abrasive, high-load bulldozer applications.
Dingtai has over 20 years of undercarriage manufacturing experience and holds ISO9001 and SGS certifications, ensuring repeatable production quality.
We use 35MnB alloy steel and deep quenching heat treatment to achieve a hardened surface and impact-resistant core for extended service life.
Core Selling Points
- Premium 35MnB Material: Rollers are forged from 35MnB steel, providing high tensile strength and excellent resistance to bending, cracking, and abrasive wear.
- Deep Quenching/Heat Treatment: Induction hardening creates HRC 50-58 surface hardness while retaining a tough core, significantly extending roller life in rocky terrain.
- Global Brand Compatibility: Double-flange rollers are engineered to match Hyundai OEM dimensions and mounting patterns for drop-in replacement on existing undercarriages.
- ISO9001/SGS Certified: Production is controlled under ISO9001 quality systems with SGS material reports, ensuring every batch meets certified material and dimensional standards.
Our catalog of Hyundai Bulldozer Track Roller-Double Flange includes various specifications, fully compatible with Hyundai excavators and bulldozers.

Technical Features
Double-flange rollers control lateral track movement, keeping the track frame aligned under heavy side loads and reducing uneven link wear.
Deep induction hardening produces a HRC 50-58 wear surface while maintaining a tough 35MnB core, preventing surface spalling and impact fracture.
Precision machined shaft bores and double-flange faces ensure correct bushing contact and oil film retention for lower rolling resistance.
Applications
- Open-pit mining and aggregate operations
- Heavy road construction and site preparation
- Quarrying and rock handling
- Demolition and waste handling
- Forestry and steep-slope dozing
Frequently Asked Questions
What is the minimum order quantity for Hyundai track rollers?
Standard MOQ is 20 pieces per specification. Trial orders and mixed-container loading may be accepted for first cooperation.
What is the typical delivery time?
Standard production takes 15-25 days after drawing confirmation or deposit receipt, depending on order quantity and current production schedule.
How deep is the heat treatment layer?
Surface hardening depth ranges from 4-8 mm depending on roller size, with HRC 50-58 on the tread surface.
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 produce from our part number or drawing?
Yes. We match OEM part numbers or custom drawings and confirm dimensions before mass production.
Do these rollers fit Hyundai excavators and bulldozers?
Yes. Double-flange designs are produced for Hyundai OEM undercarriage part numbers and equivalent aftermarket dimensions.
Maintenance Guide
- Inspect roller flange wear and oil leakage every 250 working hours; replace damaged floating seals immediately to prevent contamination.
- Check mounting bolt torque after the first 50 hours and at regular service intervals to prevent loosening under vibration.
- Measure tread wear and flange thickness; replace rollers when wear exceeds OEM limits or abnormal noise indicates internal failure.
- Use clean recommended gear oil and avoid high-pressure washing directly on seal areas to extend roller service life.
