Dingtai manufactures Mitsubishi bulldozer carrier rollers that support the upper track frame, maintain track alignment, and reduce vibration in heavy dozer applications.
As a factory-direct manufacturer, we provide comprehensive OEM services and precision machining for global distributors, dealers, and fleet maintenance teams requiring reliable undercarriage components.
These rollers solve premature wear and breakage issues caused by abrasive soil and heavy loads, preventing costly downtime and track system failures.
Dingtai has over 20 years of manufacturing experience and is ISO9001/SGS certified, ensuring consistent quality, material traceability, and repeatable production standards.
Every roller uses 35MnB material and deep quenching heat treatment to deliver a hard, wear-resistant surface with a tough impact-resistant core.
Core Product Advantages
- Premium 35MnB Material: Forged from 35MnB steel for higher tensile strength and wear resistance under extreme bulldozer loads and abrasive conditions.
- Deep Quenching / Heat Treatment: Deep quenching creates a hardened tread layer of 52–58 HRC while keeping the core tough against impact and cracking.
- Global Brand Compatibility: Direct replacement for Mitsubishi BD2 and BS3 series dozers; cross-compatible dimensions match OEM part numbers without modification.
- ISO9001 / SGS Certified: Manufacturing processes are certified for quality management, with full material reports and dimensional inspection before shipment.
Our catalog of Mitsubishi Bulldozer Carrier Roller includes various specifications, fully compatible with Mitsubishi bulldozers and related construction machinery.

Technical Features
Carrier rollers use a floating seal design that keeps lubricant in and prevents abrasive dirt, sand, and moisture from entering the bearing cavity.
The bimetal bushing and precision-machined shaft reduce friction under heavy radial loads, extending roller life and maintaining stable track movement.
Deep-quenched 35MnB steel provides a hard outer tread for wear resistance while retaining core toughness to resist impact and fatigue cracking.
Applications
- Mining and quarrying – haul roads and pit floor operations.
- Road construction – grading and earthmoving in abrasive soil.
- Land clearing and forestry – high-debris track conditions.
- Demolition and site preparation – heavy impact and uneven ground.
Frequently Asked Questions
What is the MOQ?
Standard MOQ is 1–4 pieces for stock sizes. Larger orders receive tiered factory pricing and priority production scheduling.
What is the delivery time?
Delivery time is normally 15–30 days after order confirmation, depending on quantity, customization, and sea or express shipment.
How deep is the heat treatment?
Deep quenching typically produces a hardened layer of 4–8 mm, with surface hardness controlled between 52–58 HRC.
What warranty is included?
We provide a 12-month or 2,000-hour warranty against manufacturing defects under normal operating conditions.
Can you match part numbers?
Yes. Send OEM part numbers or drawings, and we will cross-reference or manufacture to exact dimensional specifications.
Are samples available?
Sample orders are available for first-time buyers to verify fitment and quality before bulk purchasing.
Maintenance Guide
- Inspection: Check rollers for oil leaks, abnormal noise, and uneven tread wear every 250 operating hours.
- Installation: Tighten mounting bolts to OEM torque values and verify track frame alignment before returning to service.
- Replacement: Replace when tread wear exceeds OEM limits or when internal bearing clearance causes track vibration and instability.
- Lubrication: Do not disassemble sealed rollers; resealed units require clean assembly and correct oil fill.
