Dingtai manufactures double flange track rollers for Mitsubishi bulldozers. These rollers guide and support the undercarriage track frame during heavy operation.
We offer factory-direct supply with full OEM manufacturing services. Global clients receive custom machining, branding, and packaging support from our Quanzhou facility.
Heavy impact and abrasive conditions cause premature roller failure. Our reinforced double flange rollers reduce track derailment risk and extend undercarriage service intervals.
With over 20 years of engineering experience and ISO9001/SGS certified processes, Dingtai delivers consistent quality for demanding earthmoving and mining applications.
Each roller uses 35MnB steel and deep quenching to achieve 52-58 HRC. This hardening depth resists wear, cracking, and deformation under high load.
Core Selling Points
- Premium 35MnB Material: Forged from high-strength 35MnB boron steel, the roller shell resists impact fatigue and abrasive wear in harsh bulldozer undercarriage environments.
- Deep Quenching/Heat Treatment: Induction hardening achieves 52-58 HRC case depth, providing a wear-resistant surface while maintaining a tough core to prevent cracking.
- ISO9001/SGS Certified: Manufacturing processes are ISO9001 certified and SGS inspected, ensuring dimensional accuracy, material traceability, and consistent mechanical properties.
- OEM Capabilities: We produce according to OEM drawings or samples, including custom part numbers, CNC machining, and neutral packaging for distribution partners.

Technical Features
Double flange design keeps the track chain laterally aligned. Each roller absorbs machine weight while preventing derailment over uneven ground.
Floating seals retain internal lubricant and block abrasive mud. This sealed lubrication system reduces internal wear and extends maintenance intervals.
Deep-hardened 35MnB steel creates a wear-resistant outer shell over a ductile core, resisting spalling and impact fractures in rock conditions.
Applications
- Mining
- Road Construction
- Quarrying
- Forestry
- Land Reclamation
- Earthmoving
Frequently Asked Questions
What is the minimum order quantity?
We accept small trial orders. Standard MOQ is 20 pieces per part number, negotiable for stock programs.
What is the delivery time?
Sample orders ship within 7-15 days. Bulk production orders generally ship within 25-35 days after deposit receipt.
How deep is the heat treatment?
The roller surface is induction hardened to 52-58 HRC with an effective case depth of 4-8 mm depending on part number.
What warranty do you provide?
We offer a 12-month or 2,000 working hour warranty against material and manufacturing defects under normal operating conditions.
Can you match Mitsubishi part numbers?
Yes, provide the OEM part number or drawing. We confirm dimensions and manufacture an exact replacement or reverse-engineered equivalent.
What material is used?
Roller shells and shafts use 35MnB boron steel for high strength and impact resistance. Bushings are hardened and precision ground.
Do you offer customized packaging?
Yes, we provide neutral, branded, or color-box packaging according to client requirements.
How do I confirm compatibility?
Send the Mitsubishi model and part number. Our engineering team checks the mounting dimensions, flange width, and shaft bore before quotation.
Maintenance Guide
- Inspect regularly: Check for oil leakage, flange wear, and surface cracks every 250 working hours.
- Monitor track tension: Incorrect tension accelerates roller shell and flange wear; adjust according to Mitsubishi specifications.
- Replace in sets: Replace rollers in axle groups to maintain even load distribution and prevent premature failure.
- Verify installation torque: Tighten mounting bolts to specified torque and recheck after initial 50 hours.
