Dingtai manufactures Kubota track link assemblies as complete undercarriage units. Each assembly transfers drive force and supports excavator operating weight.
We are a factory-direct China manufacturer offering full OEM production, custom sizing, and reliable batch supply for global equipment buyers.
Our track link assemblies resist abrasive wear, fatigue cracking, and chain elongation. This prevents unplanned downtime and lowers replacement costs.
With over 20 years of manufacturing experience, Dingtai holds ISO9001 and SGS certifications. Production quality meets stringent North American procurement standards.
We use 35MnB steel and deep quenching to deliver consistent hardness, high tensile strength, and extended track link service life.
Core Selling Points
- Premium 35MnB Material: Track links are manufactured from high-tensile 35MnB steel, providing excellent impact resistance and reduced risk of link fracture during heavy excavator operation.
- Deep Quenching/Heat Treatment: Each link undergoes controlled quenching and tempering to achieve HRC 48–55, ensuring strong wear resistance and stable hardness across the chain.
- Precision Forging: Precision forged link bodies deliver dense grain structure and dimensional accuracy, supporting smooth rotation around sprockets and idlers without binding.
- 100% QC Inspection: Every assembly passes dimensional checks, hardness testing, and visual inspection before shipment, ensuring consistent fitment and long service intervals.
Our catalog of Kubota Track Link Assembly includes various specifications, fully compatible with Kubota excavators and compact track loaders.

Technical Features
Forged 35MnB links create a dense grain structure. Deep quenching raises surface hardness to HRC 48–55, improving resistance to rock abrasion.
Pins and bushings are induction hardened and matched to tight tolerances. This reduces friction, limits pitch elongation, and prevents sprocket skipping under load.
Track link assemblies maintain accurate pitch over long operating cycles. This stability extends sprocket and idler life while keeping Kubota compact machines productive.
Applications
- Landscaping and site preparation
- Utility trenching and pipeline installation
- Road construction and asphalt restoration
- Demolition and foundation excavation
- Agricultural drainage and material handling
Frequently Asked Questions
What is the minimum order quantity for Kubota track link assemblies?
MOQ is usually 4–10 pieces per model depending on stock. Trial orders are accepted for new buyers.
What is the delivery time?
Stock items ship in 7–15 days. Custom production requires 25–35 days after drawings and deposit confirmation.
What heat treatment depth do you apply?
Link surface hardness reaches HRC 48–55. Effective hardened depth is typically 5–10 mm, depending on link profile.
What warranty do you provide?
We provide a 12-month or 2,000-hour warranty against manufacturing defects and premature link or pin breakage.
Can you match Kubota OEM part numbers?
Yes. Send your Kubota part number or drawing. We cross-check dimensions and supply a direct replacement assembly.
Do you offer samples before bulk orders?
Yes. Sample orders are available for dimensional verification and field fitment before full container procurement.
How do you package track link assemblies?
Each assembly is packed in wooden pallets or steel crates with anti-rust protection for ocean freight.
Maintenance Guide
- Inspect track tension daily. Correct sag reduces link stress and prevents accelerated pin and bushing wear.
- Check pin and bushing wear regularly. Replace components when diameter wear exceeds OEM tolerance limits.
- Grease track link pins at required intervals. Proper lubrication prevents dry contact and reduces internal friction.
- Align sprocket and idler before installation. Misalignment causes uneven link side wear and shortened chain life.
- Monitor chain pitch elongation. Replace the full assembly when pitch exceeds Kubota specifications to protect sprockets.
