Dingtai manufactures Mitsubishi track rollers as critical undercarriage components that support machine weight and guide track chain movement.
We operate factory-direct with full OEM manufacturing services, supplying distributors, dealers, and fleet owners across North America and global markets.
Forged rollers resist abrasion and impact, preventing premature undercarriage wear, track misalignment, and costly excavator downtime in demanding ground conditions.
With over 20 years of production experience, Dingtai holds ISO9001 and SGS certifications, ensuring consistent dimensional accuracy and metallurgical reliability.
Each Mitsubishi track roller uses 35MnB steel, deep quenching, and CNC machining to achieve a hardened tread surface and extended service life.
Core Selling Points
- 20+ Years Experience: Dingtai has specialized in undercarriage components for over two decades, delivering proven track roller reliability to heavy machinery users worldwide.
- Global Brand Compatibility: Our Mitsubishi track rollers match OEM mounting dimensions and bolt patterns, providing direct replacement for ME, MM, and MS series excavators.
- Premium 35MnB Material: Roller shells are forged from 35MnB steel, offering high tensile strength and wear resistance under continuous impact and heavy machine loads.
- Deep Quenching/Heat Treatment: Tread surfaces are induction hardened to HRC 52–58, producing a deep hardened layer that resists spalling, pitting, and uneven wear.
Our catalog of Mitsubishi Track Roller includes various specifications, fully compatible with Mitsubishi excavators and bulldozers.

Technical Features
Each roller integrates a floating seal and bimetal bushing, retaining lubricant while blocking abrasive dirt, water, and fine particles from entering the rotating assembly.
Roller shells are forged from 35MnB steel and induction hardened, creating a deep martensitic layer that resists deformation under continuous crawler impact.
Precision CNC machining controls shaft and bore tolerances, ensuring smooth rotation, correct track tension, and even load distribution across the undercarriage.
Applications
- Mining: hard rock and mineral extraction with high-impact track loads.
- Road Construction: asphalt, aggregate, and subgrade compaction sites.
- Quarrying: abrasive stone handling and pit floor operations.
- Demolition: debris-laden ground conditions requiring impact-resistant rollers.
- Forestry: uneven terrain with stumps and abrasive soil.
Frequently Asked Questions
Q1: What is the minimum order quantity for Mitsubishi track rollers?
A: MOQ is usually 4 pieces per part number; trial orders are accepted for standard specifications.
Q2: How long is delivery time?
A: Standard items ship in 7–15 days; custom production typically requires 20–30 days after drawing confirmation.
Q3: How deep is the hardened layer on the roller tread?
A: Hardening depth is generally 5–10 mm depending on part number, with tread hardness HRC 52–58.
Q4: What warranty do you provide?
A: We offer 12 months or 2,000 operating hours warranty against material and manufacturing defects under normal use.
Q5: Can you match Mitsubishi OEM part numbers?
A: Yes, provide the OEM part number or drawing; our engineers cross-check dimensions and mounting compatibility before production.
Q6: Are samples available?
A: Yes, sample orders can be arranged for standard track rollers to verify fitment and quality before bulk purchasing.
Maintenance Guide
- Installation: Clean mounting surface and check bolt torque before fitting track roller to avoid looseness and uneven load.
- Lubrication: Inspect plug seals and ensure factory-filled oil remains uncontaminated; do not run rollers dry after impact damage.
- Wear Inspection: Measure tread thickness and flange wear every 500 hours; replace rollers with visible cracks, oil leaks, or sharp edge reduction.
- Replacement Interval: In abrasive mining or quarry conditions, inspect at 1,500–2,000 hours and plan replacement when wear exceeds service limits.
