Dingtai manufactures John Deere track link assemblies, the load-bearing chain components that transfer drive force and support machine weight.
We are a factory-direct supplier offering complete OEM manufacturing services to global distributors and equipment owners.
Forged and heat-treated links resist elongation and cracking, reducing unplanned downtime and premature undercarriage failure in abrasive conditions.
With over 20 years of experience, Dingtai holds ISO9001 and SGS certifications to verify consistent material and process quality.
We use 35MnB steel and deep quenching technology to achieve hardened wear surfaces and high core toughness for extended service life.
Core Selling Points
- Premium 35MnB Material: Forged 35MnB steel provides high tensile strength, impact resistance, and resistance to pitch elongation under heavy excavator loads.
- Deep Quenching/Heat Treatment: Induction hardening creates a 3–6 mm wear-resistant layer with HRC 50–56 while maintaining a tough core.
- Precision Forging/Casting: Precision-machined pin bores and consistent link pitch ensure smooth sprocket engagement and reduced internal friction.
- 100% QC Inspection: Every link assembly receives dimensional checks, hardness testing, and visual inspection before packaging and dispatch.
Our catalog of John Deere Track Link Assembly includes various specifications, fully compatible with John Deere excavators and bulldozers.

Technical Features
Link pitch and bushing bores are precision machined to ensure uniform load distribution; bimetallic bushings reduce friction and wear.
Sealed and lubricated track assemblies use floating seals to retain oil and block abrasives, extending internal pin and bushing life.
Forged 35MnB link bodies are heat treated to create hardened wear surfaces and a tough core, preventing cracking under shock loads.
Applications
- Mining
- Road Construction
- Quarrying
- Demolition
- Forestry
- Heavy Earthmoving
Frequently Asked Questions
Q1: What is the minimum order quantity (MOQ)?
MOQ is usually one set; sample orders are accepted for first-time quality verification.
Q2: What is the delivery time?
Delivery typically takes 15–30 days after deposit, depending on order quantity and customization.
Q3: How deep is the heat treatment hardening layer?
Hardened layer depth is 3–6 mm with surface hardness HRC 50–56, depending on link specification.
Q4: What warranty do you provide?
We provide a 12-month or 2,000-hour warranty against manufacturing defects under normal operating conditions.
Q5: Can you match John Deere OEM part numbers?
Yes, provide your OEM part number or drawing; we cross-reference and manufacture to the required specification.
Q6: Do you offer custom packaging?
Yes, we offer standard export packaging and custom labeling based on customer requirements.
Maintenance Guide
- Inspect link pitch and bushing wear: Check every 250 hours; replace if pitch elongation exceeds 10–15%.
- Check seals and lubrication: Look for oil leakage around pins; contamination accelerates internal wear.
- Maintain track tension: Over-tightening increases link stress and fuel consumption; under-tightening causes detracking.
- Replace in matched sets: Install new link assemblies as complete sets to avoid uneven pitch and sprocket damage.
