Product Overview
Dingtai manufactures single flange track rollers engineered to guide and support John Deere bulldozer undercarriage weight distribution during operation.
We operate as a factory-direct manufacturer providing complete OEM production services for distributors, dealers, and fleet maintenance buyers worldwide.
Precision-machined rolling surfaces and sealed lubrication reduce premature wear, preventing track misalignment and costly undercarriage downtime in demanding ground conditions.
With over 20 years of production experience, Dingtai maintains ISO9001 and SGS certified processes, delivering repeatable dimensional accuracy and verified material integrity.
Rollers are forged from 35MnB steel with deep quenching heat treatment, achieving high surface hardness for extended service life under heavy impact loads.
Core Selling Points
- Premium 35MnB Material: Forged 35MnB steel provides high tensile strength and impact resistance, reducing cracking risk under severe bulldozer load cycles.
- Deep Quenching/Heat Treatment: Precision-controlled deep quenching delivers consistent HRC hardness and wear resistance, extending service life in abrasive undercarriage environments.
- Global Brand Compatibility: Single flange rollers match John Deere OEM specifications and aftermarket dimensions for direct replacement across popular bulldozer series.
- 100% QC Inspection: Every roller undergoes dimensional, hardness, and seal integrity checks before release, ensuring zero-defect shipment to global procurement teams.
Our catalog of John Deere Bulldozer Track Roller-Single Flange includes various specifications, fully compatible with John Deere bulldozers.

Technical Features
The single flange design centers the track chain, preventing lateral movement and reducing uneven wear on links and idlers.
Floating metal seals keep lubricant in and contaminants out, allowing internal bearing surfaces to operate under a constant oil film.
Deep quenched 35MnB shells achieve high surface hardness while retaining a tough core to resist impact fracture in rocky conditions.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for John Deere single flange track rollers?
Standard MOQ is 4 pieces for mixed specification trial orders. Higher volumes receive adjusted factory pricing.
What is the delivery time for John Deere bulldozer track rollers?
Stock samples ship within 7 days. Custom production orders typically ship within 25-35 days after drawing confirmation.
What heat treatment depth does Dingtai apply?
Rollers receive deep quench hardening on the shell and flange, achieving HRC 52-56 to a controlled depth.
What warranty is provided?
Dingtai provides a 12-month or 2,000-hour warranty against material and manufacturing defects under normal use.
How do I confirm correct part number matching?
Send your John Deere OEM part number or roller drawing. Our engineers cross-reference dimensions to verify fitment.
Are these rollers suitable for aftermarket replacement?
Yes, they are engineered as direct aftermarket replacements for John Deere bulldozers, not genuine John Deere parts.
Maintenance Guide
- Inspect roller surfaces, flange edges, and seals for uneven wear or oil leaks every 250 operating hours.
- Check track tension regularly; excessive sag accelerates roller shell wear and flange contact fatigue.
- Clean mounting surfaces and torque bolts to John Deere specifications during installation to prevent loosening.
- Replace rollers in matched sets when wear exceeds OEM limits to maintain undercarriage balance and service life.
