Dingtai manufactures Caterpillar track groups, complete undercarriage assemblies delivering reliable traction and mobility for heavy construction and mining equipment.
As a factory-direct supplier, we offer comprehensive OEM manufacturing services, producing track groups to exact specifications for global equipment distributors.
Our track groups minimize downtime by resisting abrasive wear and impact breakage, even in the most demanding underfoot conditions.
Backed by over 20 years of manufacturing experience and ISO9001/SGS certifications, Dingtai delivers consistent quality and proven reliability.
We use premium 35MnB steel, deep induction quenching, and precision machining to achieve exceptional link and bushing durability.
Core Selling Points
- 20+ Years Experience: Since 1998, Dingtai has specialized in undercarriage components, refining production techniques to deliver durable track groups for global markets.
- Premium 35MnB Material: Track links and pins are forged from high-tensile 35MnB alloy steel, providing superior resistance to bending fatigue and impact fracture.
- Deep Quenching/Heat Treatment: Pins and bushings undergo induction hardening to 4–8 mm depth, achieving 55–60 HRC hardness for superior wear resistance.
- 100% QC Inspection: Every track group undergoes rigorous dimensional and material testing, ensuring zero-defect delivery and consistent fitting on Caterpillar machinery.
Our catalog of Caterpillar Track Groups includes various specifications, fully compatible with Caterpillar excavators and bulldozers.

Technical Features
Our track groups employ sealed and lubricated track (SALT) technology. Polyurethane seals retain lubricant, minimizing internal pin and bushing wear.
Deep hardened bushings with 4-8 mm case depth resist deformation under heavy loads, extending chain life in rocky conditions.
Precision forging aligns link pitch accurately, ensuring smooth engagement with sprockets and reducing vibration during heavy-duty operations.
Applications
- Mining
- Quarrying

Frequently Asked Questions
- What is the minimum order quantity (MOQ)?
- We accept orders starting from one complete track group set.
- What is the typical delivery time?
- Standard production lead time is 15–30 days, depending on order specifications and volume.
- How deep is the heat treatment on pins and bushings?
- Induction hardening achieves a case depth of 4–8 mm, providing consistent wear resistance throughout the life of the component.
- What warranty do you provide?
- All track groups are covered for 12 months or 2,000 operating hours against manufacturing defects.
- How can I confirm part number compatibility?
- Provide your original Caterpillar part number, and our engineering team will verify dimensional and interface compatibility.
- Can you customize pitch or link height?
- Yes, we adjust all critical dimensions to match OEM drawings exactly for non-standard requirements.
- Are track shoes included with the group?
- We supply either the link assembly alone or the complete track group with grouser shoes, as per order.
Maintenance Guide
Check track tension weekly to avoid excessive sprocket wear and link stretching. Inspect pins and bushings for dry surfaces or oil leaks around seals. Clean undercarriage components daily to prevent material packing in rocky or abrasive environments. Replace any seal showing lubricant leakage immediately to prevent internal wear. Rotate or replace links once pitch elongation exceeds 3% of original dimension.
