Dingtai manufactures Mitsubishi sprockets, precision drive components that transfer final drive torque and guide track chains on excavators and bulldozers.
We provide factory-direct OEM manufacturing and custom production services for global distributors, equipment dealers, and procurement teams needing reliable replacement parts.
Our sprockets resist premature tooth wear, cracking, and misalignment, reducing unplanned downtime and extending undercarriage service life in abrasive conditions.
With over 20 years of engineering experience and ISO9001/SGS certification, Dingtai delivers consistent quality and traceable production for aftermarket replacement parts.
Premium 35MnB steel and deep quenching deliver high tooth hardness and long service life under heavy loads.
Core Selling Points
- Premium 35MnB Material: Sprocket bodies are forged from high-strength 35MnB steel, delivering superior tensile strength and impact resistance under excavator track tension.
- Deep Quenching/Heat Treatment: Tooth surfaces undergo deep quenching to achieve optimal HRC hardness, minimizing abrasive wear and tooth deformation during continuous rotation.
- OEM Capabilities: We manufacture to OEM drawings or physical samples, matching pitch, bolt pattern, and hardness specifications for direct replacement.
- 100% QC Inspection: Every batch undergoes dimensional checks, hardness testing, and magnetic particle inspection to eliminate casting defects and ensure consistent quality.
Our catalog of Mitsubishi sprockets includes various specifications, fully compatible with Mitsubishi bulldozers.

Technical Features
Sprocket teeth engage track bushings under high drive torque. Correct tooth profile and pitch accuracy distribute load evenly, preventing localized stress and premature tooth failure.
Deep quenching hardens the tooth surface while maintaining a tough core. This structure resists abrasive wear and impact cracking during rock loading and high-traction operations.
Precision-machined bolt holes and pilot bore ensure full contact with the final drive hub, reducing vibration and bolt loosening in demanding terrain.
Applications
- Mining: haul road maintenance and ore loading
- Road Construction: grading, trenching, and site preparation
- Quarrying: bench clearing and stockpile management
- Demolition: high-impact undercarriage stress
Frequently Asked Questions
What is the MOQ for Mitsubishi sprockets?
Standard sizes have a low MOQ, usually 1-4 pieces for sample orders. Custom OEM production may require larger quantities depending on machining setup.
How long is delivery?
Standard catalog sprockets ship within 7-15 days. Custom-manufactured sprockets typically require 25-35 days after drawing approval.
What heat treatment depth can you achieve?
We can achieve effective case depth of 4-8 mm on tooth surfaces, with hardness controlled to HRC 50-55 for wear resistance.
Do you offer a warranty?
Yes. We provide a 12-month warranty against manufacturing defects under normal operating conditions, excluding normal wear and misuse.
How do I match my Mitsubishi part number?
Send your OEM part number, machine serial number, or a dimension drawing. Our engineers verify tooth count, pitch, bolt pattern, and hub diameter.
Can you produce discontinued Mitsubishi models?
Yes. We specialize in older and discontinued undercarriage parts. Provide drawings or sample dimensions and we can reverse engineer the sprocket.
What material do you use?
We use forged 35MnB or equivalent alloy steel, selected for high tensile strength and impact resistance in undercarriage components.
Do you provide samples?
Yes, sample orders are available for standard models. Custom samples can be arranged after tooling confirmation.
Maintenance Guide
- Inspection: Check tooth root wear and sharpening every 250 hours. Replace sprockets if teeth are hooked or cracked.
- Installation: Clean hub mating surfaces, tighten bolts to OEM torque, and verify track tension after mounting.
- Replacement: Replace sprockets together with track chains to prevent rapid wear on new components. Maintain proper track sag.
