Case Bulldozer Track Roller-Double Flange Definition: Dingtai manufactures double flange track rollers that support machine weight and guide track chains in Case bulldozer undercarriages.
Factory Direct Service: We operate as a factory-direct supplier, offering complete OEM manufacturing for global distributors, dealers, and end users seeking proven undercarriage components.
Problem Solved: Double flange rollers prevent track derailment, reduce uneven wear, and eliminate premature failure caused by lateral stress and abrasive job site conditions.
Why Us: With over 20 years of manufacturing experience and ISO9001/SGS certified processes, Dingtai delivers consistent quality and traceable quality control for every batch.
Technology: We use 35MnB alloy steel and deep quenching to achieve a hard, wear-resistant shell with a tough core for high-impact loads.
Core Selling Points
- Global Brand Compatibility: Our double flange rollers match Case OEM part numbers and major aftermarket undercarriage systems for direct installation without modification.
- Premium 35MnB Material: Roller shells are forged from 35MnB steel for high tensile strength, fatigue resistance, and reliable performance under heavy dozer loads.
- Deep Quenching/Heat Treatment: Induction hardening deepens the tread hardness to 50–58 HRC, greatly improving abrasion resistance and extending undercarriage service intervals.
- ISO9001/SGS Certified: Every batch undergoes dimensional inspection and magnetic particle testing under ISO9001 and SGS protocols, ensuring zero-defect delivery for procurement directors.
Our catalog of Case Bulldozer Track Roller-Double Flange includes various specifications, fully compatible with Case bulldozers and crawler loaders.

Technical Features
Double flange design guides the track chain laterally, preventing derailment under high side loads and uneven terrain.
35MnB shells receive deep induction hardening to 50–58 HRC, creating a hard wear surface over a ductile core that resists cracking.
Floating seals and precision-machined bores retain lubricant and block contaminants, extending bearing life in abrasive dozer applications.
Applications
- Mining: haul road maintenance and overburden handling
- Road Construction: grading, site preparation, and slope work
- Quarrying: abrasive material handling and rough terrain operation
- Landfill & Demolition: high-impact, debris-heavy environments
- Forestry: uneven trails and heavy brush clearing
Frequently Asked Questions
Q1: What is the MOQ for Case double flange track rollers?
Standard MOQ is 4–8 pieces for stock sizes. OEM orders typically require 20 or more depending on drawings.
Q2: What is the delivery time?
Stock items ship in 7–10 days. Standard production requires 25–35 days after deposit confirmation.
Q3: What heat treatment depth do you achieve?
Tread hardness is 50–58 HRC, with effective hardened depth of 8–12 mm depending on part number.
Q4: What warranty policy applies?
We provide 12 months or 2,000 working hours warranty against manufacturing defects and abnormal wear.
Q5: Can you match Case OEM part numbers?
Yes. Provide the Case part number or drawing and we cross-reference to manufacture to OEM dimensions.
Q6: Are your track rollers interchangeable with other aftermarket undercarriage systems?
Yes, our double flange rollers are machined to match OEM and major aftermarket undercarriage interfaces.
Q7: Do you offer samples?
Yes, standard samples are available for evaluation. Freight is usually customer paid or negotiable for long-term contracts.
Maintenance Guide
- Inspect tread thickness, flange wear, and oil leakage every 250 operating hours.
- Check mounting bolt torque and replace loose or damaged bolts to prevent roller misalignment.
- Monitor track sag and adjust track tension to OEM specifications to distribute load evenly.
- Replace rollers in matched sets when tread wear exceeds 20% of original diameter or flanges show cracking.
