Dingtai manufactures single flange track rollers for Caterpillar bulldozers, guiding track chains and supporting machine weight in undercarriage systems.
Factory direct status enables full OEM manufacturing services, from forging to final assembly, supporting global equipment distributors and fleet owners.
This roller prevents premature track wear and downtime. Deep-hardened surfaces resist abrasion, impact, and bending under severe bulldozer loads.
With over 20 years of undercarriage component production and ISO9001/SGS certified processes, Dingtai delivers repeatable quality for demanding applications.
Rollers are forged from 35MnB steel and undergo deep quenching to achieve high surface hardness and a durable, impact-resistant core.
Core Selling Points
- 20+ Years Experience: For over 20 years, Dingtai has specialized in undercarriage component manufacturing, delivering proven engineering and consistent quality to global clients.
- Global Brand Compatibility: Single flange rollers are machined to match Caterpillar D3 through D11 series undercarriage dimensions, ensuring direct replacement without on-site modification.
- Premium 35MnB Material: Roller shells are forged from 35MnB steel for excellent strength, hardness uniformity, and resistance to impact, bending, and fatigue failure.
- Deep Quenching/Heat Treatment: Advanced heat treatment penetrates the tread and flange, producing a hard wear surface while maintaining a tough, crack-resistant core under impact.
Our catalog of Caterpillar Bulldozer Track Roller-Single Flange includes various specifications, fully compatible with Caterpillar bulldozers and excavators.

Technical Features
The single flange design centers the track chain and resists lateral loads during turning and sidehill operation, reducing internal link wear.
Roller shells are forged from 35MnB steel and deep quenched. The hardened tread resists wear; the ductile core absorbs severe impact.
Floating seals retain internal lubricant and block abrasive contaminants, extending bearing service life in mining and earthmoving conditions.
Applications
- Mining
- Road Construction
- Quarrying
- Land Clearing
- Pipeline Construction
- Demolition
Frequently Asked Questions
What is the minimum order quantity?
Trial orders are accepted. Standard MOQ is 10 pieces per part number.
What is the delivery time?
Standard rollers ship within 7–15 days after deposit confirmation. Custom production typically requires 25–35 days.
How deep is the heat treatment?
Tread hardened layer typically ranges from 5–10 mm depending on roller size. Core hardness remains HRC 30–40 for impact resistance.
What warranty do you provide?
We provide a 12-month or 2,000-hour warranty against material and workmanship defects, excluding normal wear or misuse.
How do I confirm part number compatibility?
Provide your Caterpillar part number or drawing. Our engineers verify dimensions, flange profile, and mounting bolt pattern before production.
Are these genuine Caterpillar parts?
No, these are aftermarket replacement rollers manufactured to OEM specifications for Caterpillar bulldozers.
What material is used?
Roller shells are forged from 35MnB alloy steel, selected for hardness uniformity and impact fatigue resistance.
Can you produce rollers for D11 mining dozers?
Yes, we manufacture single flange rollers for D3 through D11 series, including heavy-duty mining applications.
Maintenance Guide
- Inspect roller tread and flange thickness every 250 operating hours. Replace rollers when wear exceeds Caterpillar limits to protect track links.
- Check floating seals for oil leakage and remove debris around seal surfaces to prevent contaminant ingress and bearing failure.
- Torque mounting bolts to Caterpillar specifications during installation, then recheck torque after the first 50 operating hours.
- Avoid aggressive counter-rotation on abrasive ground; this accelerates single flange roller wear and shortens undercarriage life.
- Replace rollers in matched sets or adjust track tension to prevent uneven loading and premature undercarriage component wear.
