Dingtai manufactures excavator track groups—complete steel track assemblies that drive, support, and stabilize crawler undercarriage equipment.
We provide factory-direct supply and full OEM manufacturing services for global dealers, contractors, and equipment distributors requiring reliable undercarriage parts.
Our track groups replace worn or broken assemblies, reducing unplanned downtime and resisting severe abrasion, impact, and fatigue on demanding jobsites.
With over 20 years of heavy machinery experience and ISO9001/SGS certified production, Dingtai supplies tested track systems for international buyers.
We use precision-forged 35MnB steel links, deep induction quenching, and sealed lubrication technology to extend service life.
Core Selling Points
- 20+ Years Experience: Dingtai has engineered and exported excavator undercarriage parts for over two decades, serving procurement directors and equipment fleets worldwide.
- Global Brand Compatibility: Our track groups are manufactured to replace major OEM undercarriages, with exact pitch, link height, and shoe bolt patterns for popular brands.
- Premium 35MnB Material: Track links are forged from high-strength 35MnB steel, providing superior tensile strength, impact toughness, and resistance to deformation.
- Deep Quenching/Heat Treatment: Induction quenching and controlled tempering create a hard wear surface while maintaining a ductile core for longer service intervals.

Technical Features
Track links are precision forged from 35MnB steel and induction hardened to achieve high tensile strength and impact resistance.
Sealed and lubricated track groups use floating seals and bimetal bushings to retain oil and block abrasive dirt ingress.
Deep quenching on pins and bushings creates a hard wear surface while maintaining a tough core for extended service life.
Applications
- Mining
- Road Construction
- Quarrying
- Demolition
- Forestry
- Heavy Infrastructure
Frequently Asked Questions
Q: What is the MOQ for excavator track groups?
A: Standard MOQ is one set, consisting of two track groups. Mixed model orders are negotiable.
Q: What is the typical delivery time?
A: 15–30 days after deposit and drawing confirmation, depending on quantity and specification.
Q: How deep is the heat treatment on track components?
A: Rail wear surfaces are induction hardened to 4–8 mm depth; pins and bushings are through-hardened for uniform wear resistance.
Q: What warranty do you provide?
A: 12 months or 2,000 operating hours, whichever comes first, under normal working conditions.
Q: Can you match OEM part numbers?
A: Yes. Send the OEM part number or drawings, and we will match dimensions, pin pitch, and bolt patterns.
Q: Are your track groups sealed and lubricated?
A: Yes. SALT track groups are available with floating seals and bimetal bushings for extended internal lubrication.
Maintenance Guide
- Use proper lifting equipment and align the track group with sprocket and idler before inserting the master pin.
- Check track tension daily on level ground; excessive tightness accelerates pin, bushing, and sprocket wear and increases rolling resistance.
- Remove packed mud, rocks, and debris from the undercarriage frequently to prevent abrasive wear and corrosion on links and bolts.
- Measure rail height, pin diameter, and bushing diameter every 500 hours; rotate or replace components when they reach manufacturer’s wear limits.
- Replace the complete track group when link rail height loss exceeds 10 percent or bushings show deep scoring and oil leakage.
