Dingtai manufactures aftermarket Caterpillar bulldozer carrier rollers, supporting track frame weight and maintaining alignment in tracked undercarriage systems.
We provide factory-direct pricing and full OEM manufacturing services for global distributors, dealers, and equipment owners seeking reliable replacement parts.
Our carrier rollers are engineered to resist tread wear, oil leakage, and flange breakage, reducing unplanned downtime and extending undercarriage life.
With over 20 years of experience and ISO9001/SGS certified production, Dingtai delivers consistent metallurgy, dimensional accuracy, and verified quality.
Premium 35MnB steel, deep induction quenching, and precision machining ensure high load capacity and long service life under severe conditions.
Core Selling Points
- Premium 35MnB Material: High-strength alloy steel provides excellent impact toughness and wear resistance in heavy bulldozer applications.
- Deep Quenching/Heat Treatment: Induction-hardened tread surfaces reach HRC 52–58 with uniform depth, preventing premature wear and cracking.
- Precision Forging/Casting: Precision-formed shells and machined components ensure dimensional accuracy and balanced rotation under load.
- 100% QC Inspection: Every carrier roller undergoes dimensional, hardness, leakage, and rotational testing before shipment to guarantee fit and reliability.
Our catalog of Caterpillar Bulldozer Carrier Roller includes various specifications, fully compatible with Caterpillar D3–D11 bulldozers and track loaders.

Delivery & Logistics
Factory-direct pricing, flexible MOQ, and reliable international shipping from Quanzhou. Standard export packaging protects carrier rollers against corrosion and impact.
Technical Features
Each carrier roller uses a precision-forged steel shell and induction-hardened tread surface to resist rolling contact fatigue and abrasive wear.
Bimetal bushings and lubricated seals maintain an internal oil film, preventing metal-to-metal contact and keeping contaminants out.
Optimized shaft and bracket alignment distributes track frame loads evenly, reducing vibration and extending undercarriage component life.
Applications
- Mining
- Road Construction
- Quarrying

Frequently Asked Questions
What is the MOQ for Caterpillar bulldozer carrier rollers?
Standard MOQ is 1–4 pieces for trial orders. Bulk pricing applies from 20 pieces per part number.
What is the delivery time?
Standard carrier rollers ship in 15–25 days. Custom production may require 30–45 days depending on order volume.
What heat treatment depth do you provide?
Tread surfaces receive induction hardening at 3–5 mm depth, with hardness HRC 52–58.
What warranty do you offer?
We provide 12 months or 2,000 working hours warranty against manufacturing defects.
How do I confirm part number matching?
Provide your Caterpillar part number or drawing. We cross-check dimensions, bolt pattern, and shaft specifications before production.
Can you produce custom dimensions or private labeling?
Yes, we manufacture to OEM drawings, samples, and custom packaging requirements.
Are your carrier rollers genuine Caterpillar parts?
No, we supply aftermarket replacement parts compatible with Caterpillar undercarriage systems.
Maintenance Guide
- Inspect carrier rollers every 250 operating hours for oil leaks, tread wear, abnormal noise, and excessive heat.
- Check mounting bolts with a torque wrench every 500 hours; loose bolts accelerate flange wear and cause track misalignment.
- Replace carrier rollers when tread surface wear exceeds 20 percent or internal oil contamination appears during inspection.
- Use only specified lubricants during rebuilds and avoid mixing oil types to maintain seal integrity.
