Dingtai manufactures Hyundai bulldozer sprocket segments. These precision undercarriage components transfer final drive torque directly into the track chain assembly.
We operate a factory-direct manufacturing model and supply comprehensive OEM services to construction machinery distributors and equipment owners worldwide, efficiently.
Poorly machined segments cause uneven sprocket wear and track slippage. Our hardened segments resist abrasion and extend undercarriage service intervals.
With over 20 years of manufacturing experience, Dingtai maintains ISO9001 and SGS certified quality systems for consistent, inspectable product performance.
Each segment is forged from premium 35MnB steel and deep quenched to achieve high surface hardness without sacrificing core toughness.
Core Selling Points
- Premium 35MnB Material: Forged from premium 35MnB steel for high tensile strength and superior resistance to impact loads common in bulldozer applications.
- Precision Forging: Die forging ensures exact bolt hole alignment and tooth profile consistency for direct OEM fitment without field modification.
- Deep Quenching/Heat Treatment: Deep quenching delivers uniform hardness and extended wear life under severe abrasive mining, quarrying, and heavy earthmoving conditions.
- 100% QC Inspection: Every finished segment undergoes dimensional inspection, hardness testing, and thread verification before shipment to prevent field failures.

Technical Features
The precision-forged tooth profile matches track chain pitch to ensure smooth engagement and reduce impact stress on final drive components.
Deep quench hardening creates a martensitic surface layer while the core remains ductile, preventing tooth cracking under heavy shock loads.
CNC bolt hole machining guarantees exact bolt circle alignment, preventing uneven torque distribution and premature final drive failure.
Applications
- Mining operations
- Road construction
- Quarry and aggregate production
- Land clearing and forestry
- Dam and infrastructure projects
Frequently Asked Questions
Q: What is the MOQ for Hyundai bulldozer segments?
A: MOQ is flexible, typically 1–4 pieces for stock items. Higher-volume pricing is available for fleet replacement orders.
Q: How long is delivery?
A: Stock parts ship within 7–15 days. Custom production requires 25–35 days after drawing or sample approval.
Q: What is the heat treatment depth?
A: Surface hardening depth reaches 6–10 mm, with surface hardness controlled at HRC 48–55 depending on material grade.
Q: What warranty policy applies?
A: We provide a 12-month or 2,000-hour warranty against manufacturing defects under normal operating conditions.
Q: Do you match Hyundai OEM part numbers?
A: Yes. Provide the part number, drawing, or sample; we match bolt pattern, tooth profile, and material specification exactly.
Q: Can I order a trial set before bulk purchase?
A: Yes. Trial orders are accepted to verify fitment and performance before confirming full fleet quantities.
Maintenance Guide
- Installation: Clean hub mounting faces and replace bolts with OEM-spec fasteners. Tighten bolts in a star pattern to specified torque.
- Inspection: Check tooth profiles for sharpening, wear depth, or cracks every 250 service hours. Monitor bolt torque after the first 50 hours.
- Wear Limits: Replace segments when tooth wear exceeds 25% of original profile or when track chain pitch elongation causes uneven drive engagement.
- Replacement: Replace segments in complete sets to maintain balanced drive loads. Adjust track sag according to Hyundai specifications after installation.
