Dingtai manufactures Komatsu bulldozer track shoe assemblies as direct replacement components. They secure to track chains and deliver traction, stability, and weight distribution.
We operate as a factory-direct supplier with full OEM manufacturing services. Global clients receive consistent dimensions, material specifications, and finish quality without intermediary markups.
Our track shoe assemblies resist bending, cracking, and premature grouser wear. This prevents unplanned downtime in abrasive earthmoving conditions and extends undercarriage service intervals.
With over 20 years of undercarriage manufacturing experience, Dingtai maintains ISO9001 and SGS certified processes. Every batch is documented for material traceability and dimensional accuracy.
We use 35MnB steel with deep quenching and tempered hardness. This technology improves impact toughness and wear resistance across the grouser, rail seat, and bolt holes.
Core Selling Points
- Premium 35MnB Material: High-strength 35MnB steel delivers superior tensile and fatigue resistance under heavy bulldozer loads, preventing shoe deformation and premature track system failure.
- Deep Quenching/Heat Treatment: Controlled quenching and tempering achieve HRC 48-56 surface hardness with deep hardened layers, extending grouser and rail seat wear life in abrasive conditions.
- Precision Forging/Casting: Hot forging aligns grain structure and eliminates voids. Precision-machined bolt holes and interfaces ensure exact fit with Komatsu track chains and hardware.
- 100% QC Inspection: Every track shoe assembly undergoes dimensional checks, hardness testing, and visual inspection before packing, reducing field installation issues and warranty claims.
Product Range
Our catalog of Komatsu Bulldozer Track Shoe Assembly includes various specifications, fully compatible with Komatsu bulldozers from D20 to D475 series.

Technical Features
Hot forged 35MnB steel provides uniform grain structure and high tensile strength. This reduces cracking under shock loading and bending stress in rocky ground conditions.
Deep induction hardening creates a wear-resistant surface while maintaining a ductile core. The result is long grouser life and resistance to abrasive material loss.
Precision-machined bolt holes and contact faces align with Komatsu track chains. Tight tolerances prevent loosening, uneven wear, and stress concentration at fastening points.
Applications
- Mining: hard rock, overburden removal, high-abrasion haul roads.
- Road Construction: grading, ripping, and embankment work.
- Quarrying: aggregate handling and pit floor cleanup.
- Forestry: steep terrain and mixed soil traction.
- Landfill and Demolition: high-impact, debris-heavy environments.
Frequently Asked Questions
What is the MOQ for Komatsu track shoe assemblies?
MOQ is usually 20 pieces per model. Sample orders are available for first-time dimensional verification.
What is the delivery time?
Production takes 15-30 days after deposit approval, depending on order quantity and customization requirements.
How deep is the heat treatment?
Surface hardness is HRC 48-56 with hardened depth between 4 mm and 8 mm on grouser and rail areas.
What warranty do you provide?
We provide 12 months or 2,000 working hours against manufacturing defects, not normal wear or misuse.
Can you match Komatsu part numbers?
Yes. Provide the OEM part number or drawing, and we will cross-reference dimensions to produce an exact replacement.
Are track bolts and nuts included?
Track shoe assemblies normally include bolts and nuts according to Komatsu torque specifications unless otherwise requested.
Do you offer custom grouser height?
Yes. We can customize single, double, or triple grouser profiles and grouser height based on operating conditions.
Maintenance Guide
- Clean chain link seats and track shoe contact surfaces before installation. Remove dirt, rust, and old sealant to ensure full metal-to-metal contact.
- Install bolts from the center outward and tighten to Komatsu specified torque. Recheck torque after the first 50 engine hours.
- Inspect grouser height and bolt condition every 250 hours. Replace when grouser wear exceeds 50 percent or cracks appear near bolt holes.
- Replace track shoe assemblies in full sets when excessive wear or damage occurs. Mixing old and new shoes creates uneven track pitch and accelerates undercarriage wear.
