Dingtai manufactures Mitsubishi bulldozer track chain assemblies, the core undercarriage component that transfers drive power and supports machine weight.
We provide factory-direct supply with comprehensive OEM manufacturing services, serving distributors and equipment owners across global heavy machinery markets.
Our heat-treated track chains prevent premature downtime by resisting elongation, pin wear, and link breakage in demanding dozer applications.
With over 20 years of undercarriage production experience, Dingtai maintains ISO9001 and SGS quality certifications for consistent reliability.
We use 35MnB steel and deep induction quenching to deliver hardened, long-wearing track chain assemblies engineered for Mitsubishi bulldozers.
Core Selling Points
- Premium 35MnB Material: Track links are forged from high-tensile 35MnB steel, delivering superior tensile strength and resistance against elongation under heavy bulldozer loads.
- Deep Quenching/Heat Treatment: Advanced induction hardening achieves HRC 50-56 and 4–8mm case depth, ensuring long wear life in abrasive conditions.
- Precision Forging/Casting: Precision-forged links and heat-treated pins guarantee accurate pitch alignment, reducing internal friction and extending undercarriage service life.
- ISO9001/SGS Certified: Every assembly is produced under ISO9001 quality systems and verified by SGS inspection, ensuring zero-defect delivery.
Our catalog of Mitsubishi Bulldozer Track Chain Assembly includes various specifications, fully compatible with Mitsubishi BD2 and BS3 series bulldozers.

Technical Features
Heat-treated 35MnB links undergo induction hardening, creating a wear-resistant case while maintaining a tough core to resist impact and cracking.
Precision-machined pins and bushings work with sealed lubrication to minimize internal friction, reduce heat generation, and extend track chain service intervals.
Forged link construction delivers uniform grain flow, preventing pitch elongation and ensuring stable track tension under high drawbar pull.
Applications
- Mining operations
- Road construction
- Quarrying and aggregate processing
- Landfill and site development
- Forestry and land clearing
Frequently Asked Questions
1. What is the minimum order quantity?
Standard Mitsubishi track chain assemblies have an MOQ of one set. Custom OEM production typically starts at five sets.
2. What is the delivery time?
Standard models ship within 15–25 days after deposit. Custom orders require 30–45 days depending on quantity and specifications.
3. What is the heat treatment depth?
Link treads are induction hardened to 4–8mm. Pins and bushings receive 2–4mm case depth for balanced wear resistance.
4. What warranty policy applies?
We provide a 12-month or 2,000-working-hour warranty against manufacturing defects under normal operating conditions.
5. Can you match Mitsubishi part numbers?
Yes. Provide the OEM part number or sample, and we cross-reference it to manufacture an exact-fit replacement.
6. Do assemblies include bolts and nuts?
Yes. Each track chain assembly includes links, pins, bushings, bolts, and nuts unless otherwise specified.
Maintenance Guide
- Inspect track tension daily. Incorrect tension accelerates chain link, pin, and sprocket wear.
- Check pin and bushing lubrication points regularly. Replace seals if oil leakage or contamination appears.
- Measure track sag and pitch elongation every 250 hours. Replace the chain when elongation exceeds 3 percent.
- Keep the undercarriage clean. Remove packed debris to prevent premature wear and reduce rolling resistance.
