Dingtai manufactures Yanmar track rollers as critical undercarriage components that guide, support, and stabilize the track system during excavator operation.
As a factory-direct manufacturer, we provide OEM replacement track rollers and custom manufacturing services for Yanmar distributors and fleet owners worldwide.
Our rollers resist premature wear, flange cracking, and oil leakage, reducing downtime and extending track chain life on demanding job sites.
With over 20 years of experience and ISO9001/SGS certification, Dingtai delivers consistent quality and traceable material certifications for every batch.
Each Yanmar track roller uses premium 35MnB steel and deep quenching heat treatment to achieve a hardened tread and core toughness.
Core Selling Points
- Premium 35MnB Material: Forged from 35MnB alloy steel, each roller provides high tensile strength, impact resistance, and reliable load-bearing capacity in compact equipment.
- Deep Quenching/Heat Treatment: Induction hardening creates a deep, uniform HRC 52-58 tread layer, extending service life and reducing surface spalling.
- OEM Capabilities: We manufacture to original Yanmar drawings or samples, ensuring exact bolt patterns, shaft dimensions, and fitment tolerances.
- ISO9001/SGS Certified: Production is controlled under ISO9001 procedures, with SGS material and dimensional inspection reports available for every order.
Our catalog of Yanmar track rollers includes various specifications, fully compatible with Yanmar ViO, SV, and B series excavators and compact equipment.

Technical Features
Each roller features a sealed and lubricated design. Floating seals retain oil while excluding abrasive dirt, extending service intervals in harsh environments.
Precision-machined bimetallic bushings or tapered roller bearings reduce friction heat and maintain accurate alignment under heavy side loads.
Deep induction hardening on the tread surface provides abrasion resistance, while the core remains tough to absorb impact and prevent cracking.
Applications
- Urban excavation and utility trenching
- Road construction and site development
- Demolition and material handling
- Landscaping and agricultural earthmoving
- Quarrying and mining support operations
Frequently Asked Questions
What is the minimum order quantity for Yanmar track rollers?
Standard MOQ is 10 units per part number. Trial orders of 1-2 units are available for in-stock specifications.
How long is delivery?
Stocked rollers ship within 7-10 working days. Custom production orders typically require 25-35 working days depending on quantity.
What heat treatment depth do the rollers have?
Tread surface hardness is HRC 52-58 with an effective hardening depth of 6-10 mm, depending on the Yanmar model.
What is the warranty policy?
We provide a 12-month or 2,000-hour warranty against manufacturing defects, excluding normal wear, misuse, or improper installation.
How do I confirm the correct Yanmar part number?
Send your OEM part number, machine model, and photos or drawings. Our engineers cross-check dimensions before production.
Are these genuine Yanmar parts?
No. These are aftermarket OEM-quality replacement rollers manufactured by Dingtai to match Yanmar specifications.
Can you produce custom track rollers from drawings?
Yes. We manufacture custom dimensions, bolt patterns, and hardness profiles based on customer drawings or samples.
Maintenance Guide
- Installation: Clean mounting surfaces and torque bolts to Yanmar specifications. Verify all rollers align evenly on the track frame.
- Inspection: Inspect tread surfaces weekly for spalling, uneven wear, or oil leakage around seals. Replace damaged rollers immediately to protect the track chain.
- Lubrication: Do not grease sealed rollers unless specified. Use the recommended oil type for lifetime lubricated units.
- Replacement Interval: Replace rollers when tread wear exceeds 20-25% of original diameter or when internal play causes track misalignment.
