Dingtai manufactures Hyundai bulldozer carrier rollers. These rollers support the track chain, maintain alignment, and reduce vibration in demanding undercarriage systems.
We operate as a factory-direct supplier. Our OEM manufacturing services provide complete undercarriage solutions for global Hyundai equipment distributors and end users.
Our carrier rollers solve premature wear, oil leakage, and flange breakage. They reduce unscheduled downtime in high-impact track applications.
With over 20 years of undercarriage production experience, Dingtai holds ISO9001 and SGS certifications. Our quality system ensures repeatable, measurable performance.
We use 35MnB hardened steel and deep quenching. These processes deliver high surface hardness and a durable core for extended service life.
Core Selling Points
- Global Brand Compatibility: Direct replacement for Hyundai dozer models. We cross-reference OEM part numbers to ensure exact mounting dimensions and track pitch compatibility.
- Premium 35MnB Material: Forged 35MnB steel provides high tensile strength. It resists impact deformation and abrasive wear better than standard carbon steel rollers.
- Deep Quenching/Heat Treatment: Induction hardening penetrates deep into the tread. Surface hardness reaches HRC 52-58, extending roller life in abrasive conditions.
- ISO9001/SGS Certified: Production follows ISO9001 quality management. SGS material reports verify chemical composition and heat treatment results before shipment.
Our catalog of Hyundai Bulldozer Carrier Rollers includes various specifications, fully compatible with Hyundai bulldozers and crawler tractors.

Technical Features
Carrier rollers use floating seals to keep lubricant in and dirt out. This design maintains a constant oil film between bushing and shaft.
Induction-hardened treads reach HRC 52-58. The hardened layer resists abrasive wear while the core absorbs heavy impact loads.
Precision-machined bimetal bushings reduce friction and operating temperature. Tight tolerances prevent premature flange wear and track misalignment.
Applications
- Mining: Supports track frames in high-abrasion ore and overburden conditions.
- Road Construction: Maintains alignment during continuous dozing and grading operations.
- Quarrying: Resists rock impact and dust ingress in crusher and pit environments.
- Landfill and Forestry: Handles high-debris undercarriage work with sealed protection.
Frequently Asked Questions
1. What is the MOQ for Hyundai bulldozer carrier rollers?
Our regular MOQ is 10 pieces per specification. Mixed models are accepted for initial trial orders.
2. What is the delivery time?
Standard production takes 15-30 days. Stocked standard sizes can ship within 7 days after deposit.
3. How deep is the heat treatment layer?
The induction hardening depth is generally 5-10 mm, depending on roller diameter and customer specifications.
4. What is the warranty policy?
We provide 12 months or 2,000 operating hours against manufacturing defects under normal working conditions.
5. Can you match part numbers?
Yes. Send OEM part numbers, drawings, or dimensions. We will cross-reference and confirm interchange before quotation.
6. Do you accept sample orders?
Sample orders are available. We can produce one or two test pieces before full production.
Maintenance Guide
- Installation: Verify carrier roller mounting bolt torque. Ensure frame bores are clean and free of burrs before installation.
- Inspection: Check for oil leakage, uneven tread wear, or flange contact every 250 service hours.
- Replacement: Replace rollers when tread wear exceeds 20% or when floating seal leakage is visible.
- Lubrication: Do not open sealed rollers. Internal oil is lifetime-filled; field greasing is not required.
