Product Definition: Dingtai manufactures complete Liebherr track groups—track chains, shoes, pins, bushings, and fasteners—engineered to transfer machine weight and tractive effort effectively.
Service Advantage: Our factory-direct status supports full OEM manufacturing services, including custom shoe widths, link pitch, and assembled track groups for global equipment distributors.
Problem Solved: This track group resists link cracking, pin elongation, and bushing wear, reducing unscheduled downtime in abrasive excavation and grading applications.
Why Us: Backed by over 20 years of manufacturing experience and ISO9001/SGS certified processes, we deliver dimensionally accurate undercarriage components with consistent metallurgical quality.
Technology: We use 35MnB steel, deep induction hardening, and precision machining to achieve a tough, wear-resistant track group built for high-impact loads.
Core Selling Points
- Premium 35MnB Material: Track links and bushings forged from 35MnB steel deliver high tensile strength, impact toughness, and resistance to abrasive wear.
- Deep Quenching/Heat Treatment: Induction hardening creates a 50–58 HRC wear surface on pins and bushings while retaining ductile core strength.
- Global Brand Compatibility: Direct replacement for Liebherr excavator and dozer models, matching OEM pitch, pin diameter, shoe width, and bolt pattern.
- 100% QC Inspection: Every assembled track group undergoes dimensional verification, hardness testing, and full assembly inspection before shipment.

Delivery & Logistics
Factory-direct pricing, flexible MOQ from one complete track group, and export-grade packaging. We ship by container or bulk to global ports.
Technical Features
Track links are hot forged from 35MnB steel and induction hardened on the rail surface, creating a wear-resistant contact area for rollers.
Pins and bushings are case-hardened to 50–58 HRC; the bushing bore and pin surface form a low-friction bearing pair, reducing internal wear and track pitch elongation.
Optional sealed track groups use floating face seals to retain lubricant and block abrasive ingress, extending service intervals in dusty or wet conditions.
Applications
- Mining
- Road Construction
- Quarrying
- Demolition
- Heavy Civil Earthmoving
- Forestry
Frequently Asked Questions
What is the MOQ for Liebherr track groups?
MOQ is one complete track group or one set. Mixed models can be combined in one container to reduce freight cost.
How long is delivery?
Standard production takes 25–35 days after drawing confirmation or deposit. Stock items ship within 7–10 days.
How deep is the heat treatment?
Effective case depth is 4–8 mm on pins and bushings, with surface hardness of 50–58 HRC.
What warranty do you provide?
12 months or 2,000 hours under normal working conditions, covering material and manufacturing defects.
How do I confirm part number matching?
Send your Liebherr model, serial number, or original drawing. We verify pitch, pin diameter, shoe width, and bolt pattern.
Can I order individual track components?
Yes, complete assembled track groups or individual chains, shoes, bolts, and nuts are available.
Do you offer OEM branding?
We supply neutral packaging or customer-specified branding according to OEM requirements.
Maintenance Guide
- Inspection: Check pin and bushing wear, link cracks, and shoe bolt torque every 250 working hours.
- Installation: Install matched left and right track groups; tighten shoe bolts to OEM torque and recheck after 50 hours.
- Wear Limits: Replace the track group when bushing outer wear exceeds 10–15% or grouser height loss exceeds 25%.
- Sealed Groups: For sealed track groups, do not regrease. Inspect seals for oil leakage and replace damaged seals promptly.
- Storage: Store indoors and coat machined surfaces with rust preventive oil if long-term storage is required.
