Dingtai manufactures Yanmar track link assemblies—forged undercarriage chain systems transferring machine weight and drive torque through pins, bushings, and links.
We provide factory-direct supply and comprehensive OEM manufacturing services for global equipment distributors, rental fleets, and aftermarket parts buyers.
Our assemblies resist elongation, pin wear, and cracking, reducing unplanned downtime in demanding excavator and compact track loader operations.
With over 20 years of manufacturing experience and ISO9001/SGS-certified quality systems, Quanzhou Dingtai Engineering Machinery Co., Ltd. delivers traceable undercarriage components.
Premium 35MnB steel and deep quenching processes produce hardened link bodies and bushings with balanced core toughness and surface hardness.
Core Selling Points
- Premium 35MnB Material: Forged 35MnB steel offers high tensile strength and wear resistance, extending track link life under heavy impact and abrasive conditions.
- Deep Quenching/Heat Treatment: Deep surface quenching achieves HRC 48–55 on pins and bushings, preventing premature wear and ensuring consistent hardness across the contact zone.
- 100% QC Inspection: Every link assembly undergoes dimensional, hardness, and visual inspection before packing, guaranteeing zero-defect delivery to your warehouse.
- OEM Capabilities: We manufacture to OEM drawings or sample part numbers, providing direct replacement Yanmar track links without fitment issues.
Product Range
Our catalog of Yanmar Track Link Assembly includes various specifications, fully compatible with Yanmar excavators and compact track loaders.

Technical Features
Forged link bodies distribute track tension evenly, preventing stress concentrations. Precision pin-to-bore interference fit keeps the assembly rigid under side loads.
Deep-quenched pins and bushings create a wear-resistant contact surface while retaining a tough core, reducing the risk of impact fracture.
Controlled link pitch tolerances maintain correct sprocket engagement, preventing accelerated wear and track slippage on compact excavators.
Applications
- Mining and quarrying support equipment
- Road construction and utility excavation
- Urban infrastructure and trenching
- Landscaping and agricultural material handling
- Demolition and scrap handling
Frequently Asked Questions
1. What is the minimum order quantity for Yanmar track link assemblies?
We accept low MOQ from 1 set for sample testing, with bulk pricing available for larger orders.
2. How long is delivery?
Standard production takes 15–25 days; stock items ship within 7 days.
3. How deep is the heat treatment?
Surface hardness reaches HRC 48–55 with hardened depth of 3–6 mm depending on link size and application requirements.
4. What warranty do you offer?
We provide 12 months against manufacturing defects under normal operating conditions.
5. Can you match my Yanmar part number?
Yes. Provide the OEM part number or drawing; we verify and cross-reference to produce an exact replacement.
6. Are these aftermarket parts compatible with genuine Yanmar undercarriage components?
Yes. Our track links are manufactured to OEM dimensions and pitch tolerances for direct fitment.
7. What material is used in the track link assembly?
Forged 35MnB steel with deep quenching delivers maximum wear resistance and impact strength.
Maintenance Guide
- Inspect track sag daily and adjust tension to OEM specification to avoid accelerated link wear.
- Keep undercarriage clean; remove debris from pins and bushings after operation to prevent abrasive damage.
- Check sprocket engagement; replace worn links before pitch elongation exceeds 3% of original length.
- Torque all track shoe bolts to specification during initial 50-hour service and every 250 hours thereafter.
