Dingtai manufactures complete Mitsubishi bulldozer undercarriage parts: rollers, idlers, sprockets, chains, and shoes. These components support machine weight and drive track systems.
We operate factory-direct with comprehensive OEM manufacturing services, supplying replacement undercarriage components to global dealers, fleets, and end users with exact specification control.
Severe abrasive ground quickly destroys inferior parts. Our components resist wear, reduce downtime, and solve recurring breakage problems in high-impact dozer applications.
With 20+ years of heavy machinery manufacturing experience, Dingtai maintains ISO9001 and SGS certification, ensuring consistent quality, traceability, and reliable undercarriage performance.
We use 35MnB steel and deep quenching technology to produce hardened wear surfaces, delivering longer service life under heavy load and abrasive conditions.
Core Selling Points
- Premium 35MnB Material: Forged or cast shells made from 35MnB alloy steel provide high tensile strength and impact resistance in demanding conditions.
- Deep Quenching/Heat Treatment: Induction hardening creates a martensitic wear layer with HRC 50-55, extending service intervals and reducing replacement frequency.
- Global Brand Compatibility: Precision dimensions match Mitsubishi BD2, BS3, D30, D31 and equivalent OEM part numbers for direct bolt-on replacement.
- ISO9001/SGS Certified: Strict production control and third-party testing verify material composition, hardness, and dimensional accuracy before shipment.
Our catalog of Mitsubishi Bulldozers undercarriage parts includes various specifications, fully compatible with Mitsubishi BD2, BS3, D30, D31 series bulldozers and equivalent equipment.

Technical Features
Track rollers and idlers use floating seals to retain internal oil and exclude mud, sand, and moisture, preventing premature bearing failure.
Induction-hardened 35MnB shells form a deep martensitic layer that resists rolling contact fatigue, spalling, and abrasive wear under heavy bulldozer loads.
Precision-machined bores and bimetal bushings maintain shaft alignment, reduce friction, and extend undercarriage life in continuous high-impact operations.
Applications
- Mining
- Road Construction
- Quarrying
- Forestry
- Demolition
- Earthmoving
Frequently Asked Questions
1. What is the minimum order quantity?
MOQ is usually 1–4 pieces per part number; mixed containers and trial orders are accepted.
2. What is the delivery time?
Delivery is typically 15–30 days after order confirmation, depending on quantity and production schedule.
3. What is the heat treatment depth?
Track roller shells are hardened to a depth of 4–8 mm with HRC 50–55; track chains are hardened to HRC 38–45.
4. What warranty do you provide?
We provide 12 months or 2,000 working hours warranty against material and workmanship defects under normal operation.
5. Can you match OEM part numbers?
Yes. Supply the OEM part number, drawing, or dimensions, and we will match the exact replacement specification.
6. Do you provide samples?
Stock samples are available. Custom samples may require a tooling charge before mass production.
7. How are parts packaged for export?
Parts are packed in standard export wooden pallets or crates with anti-rust protection and proper shipping marks.
Maintenance Guide
- Daily Track Tension Check: Inspect track sag each shift and adjust tension to Mitsubishi specifications; incorrect tension accelerates wear.
- Weekly Roller Inspection: Check track rollers and idlers for oil leaks, flange wear, or abnormal heat; replace damaged units immediately.
- Clean Undercarriage: Remove packed mud, rock, and debris after operation to reduce abrasive friction and prevent seal damage.
- Fastener Torque: Re-torque track shoe bolts at initial 50 hours, then every 250 hours or as specified by the OEM.
