Dingtai manufactures Liebherr track link assemblies, the main undercarriage component connecting track shoes and transferring machine weight to the ground.
Factory-direct production supports full OEM manufacturing services, from forging to finished assembly, meeting strict specifications for global clients.
This assembly resists elongation, cracking, and premature wear, preventing costly undercarriage downtime and extending service intervals in demanding earthmoving applications.
With over 20 years of undercarriage manufacturing experience, Dingtai holds ISO9001 and SGS certification, ensuring consistent quality and dimensional accuracy.
We use 35MnB steel, precision forging, and deep quenching to deliver hardened link bodies with high tensile and fatigue resistance.
Core Selling Points
- Premium 35MnB Material: Forged from 35MnB steel, these links provide high tensile strength, wear resistance, and resistance to elongation under heavy loads.
- Deep Quenching/Heat Treatment: Hardened by deep quenching and tempering, link bodies achieve uniform HRC 50–58 hardness, balancing wear life with impact toughness.
- Global Brand Compatibility: Our track link assemblies are precision-matched to Liebherr R900, R924, R934, R944, R954, R964, and PR series undercarriage specifications.
- ISO9001/SGS Certified: All production is controlled under ISO9001 quality systems with SGS material certification, ensuring dimensional accuracy and full batch traceability.
Our catalog of Liebherr Track Link Assembly includes various specifications, fully compatible with Liebherr excavators and bulldozers.

Technical Features
Precision-forged link bodies maintain exact pitch dimensions, preventing uneven load distribution and extending pin and bushing service life.
Deep quenching forms a high-hardness martensitic wear surface while retaining a tough core, reducing crack propagation under severe excavator impact.
Sealed and lubricated variants use floating seals and bimetal bushings to retain lubricant and exclude abrasive dirt, reducing internal wear.
Applications
- Mining and quarrying: hard rock excavation and ore loading
- Road construction: subgrade preparation and trenching
- Demolition and heavy civil works
- Aggregate handling and material processing
- Forestry and land clearing
Frequently Asked Questions
Q1: What is your MOQ for Liebherr track link assemblies?
A1: MOQ is typically 10 sets per part number. Mixed models are accepted for first trial orders.
Q2: What is the delivery time?
A2: Standard production time is 25–35 days after drawing confirmation and deposit. Sample orders may ship in 15 days.
Q3: How deep is the heat treatment?
A3: Quenching depth is controlled to meet OEM requirements, typically 8–12 mm on rail and link body sections.
Q4: What warranty do you provide?
A4: We provide 12 months or 2,000 operating hours, covering material and manufacturing defects under normal use.
Q5: Can you match Liebherr part numbers?
A5: Yes. Provide your part number or drawing; we cross-reference and manufacture to original dimensions and tolerance standards.
Q6: Do you offer samples?
A6: We can supply one set as a pre-production sample for inspection and fitment before mass production.
Maintenance Guide
- Before installation, measure track pitch and bushing outer diameter to confirm components are within specifications.
- Inspect sprockets and idlers for wear, as worn components accelerate new link assembly wear.
- Check track tension every 250 operating hours; overtightening increases link and bushing loads.
- Replace link assemblies when rail wear exceeds 25% of original height or when cracks appear near pin bosses.
