Dingtai manufactures Volvo track rollers as critical undercarriage components that support machine weight and guide the track chain during operation.
Factory-direct production offers comprehensive OEM manufacturing services for global clients, reducing procurement layers and ensuring direct technical communication.
Our rollers prevent unplanned downtime through hardened tread surfaces, precision sealing, and impact-resistant designs that resist wear and breakage.
With over 20 years of undercarriage manufacturing and ISO9001/SGS certified processes, we deliver repeatable quality for demanding US procurement standards.
Forged 35MnB steel and deep induction quenching produce HRC52-58 surface hardness, maximizing service life in abrasive and high-load conditions.
Core Selling Points
- Premium 35MnB Material: Forged 35MnB steel provides high strength and impact resistance, reducing premature failure under heavy undercarriage loads.
- Deep Quenching/Heat Treatment: Induction hardening produces HRC52-58 tread hardness and 8-12 mm case depth for superior wear resistance in abrasive ground conditions.
- ISO9001/SGS Certified: Manufacturing processes follow ISO9001 quality management and SGS material inspection, ensuring consistent procurement grade components.
- OEM Capabilities: We match Volvo OEM drawings, dimensions, and interface details for direct replacement fit and performance without modification.

Technical Features
Floating seal technology uses two precision-ground metal rings to prevent oil leakage and block mud, sand, and water from entering the roller cavity.
A bimetal bushing between the roller shell and shaft improves load distribution, reduces friction, and extends service life under continuous impact.
Induction hardening on the tread and flange delivers HRC52-58 surface hardness while retaining a tough core to resist cracking and spalling.
Applications
- Mining and Quarrying: Heavy continuous travel over crushed rock and abrasive ore requires high surface hardness.
- Road Construction: Frequent steering, grading, and trenching loads demand stable roller guidance.
- Demolition and Recycling: Sharp debris and uneven ground increase impact and seal contamination risk.
- Forestry and Land Clearing: Stumps, roots, and soft terrain require strong flanges and reliable sealing.
Frequently Asked Questions
What is the MOQ for Volvo track rollers?
Standard models have a 2-piece MOQ. Custom OEM rollers may require 20 pieces depending tooling and dimensions.
What is the delivery time?
Production takes 15–30 days after deposit confirmation, depending on order quantity and specification.
What is the heat treatment depth?
Tread surface hardness is HRC52-58 with an effective case depth of 8–12 mm.
What is the warranty policy?
We provide 12 months or 2,000 operating hours coverage, whichever comes first, against material and manufacturing defects.
How do I match Volvo part numbers?
Send your existing part number, drawing, or machine serial number. Our engineers verify dimensions and hub configuration before quotation.
Are these genuine Volvo parts?
No. These are aftermarket replacement parts manufactured to Volvo OEM specifications, not genuine Volvo branded components.
Can you supply sample orders?
Yes, sample orders are available for testing. Standard MOQ may apply for subsequent bulk orders.
Maintenance Guide
- Inspect rollers every 250 service hours for oil leaks, flange wear, cracks, and abnormal noise.
- Measure tread and flange thickness with calipers; replace components worn beyond 20% of original dimensions.
- Keep track tension adjusted to Volvo specifications to prevent uneven roller loading and accelerated wear.
- Replace rollers in matched pairs or sets to maintain balanced undercarriage load distribution.
