Top Description
Dingtai manufactures John Deere bulldozer track chain assemblies, the critical undercarriage component that transfers machine weight and drive torque.
We operate as a factory-direct supplier with comprehensive OEM manufacturing capabilities, serving distributors and equipment owners throughout North America.
Our track chains resist elongation, seal failure, and breakage, minimizing unscheduled downtime and reducing cost per operating hour.
Dingtai brings over 20 years of undercarriage engineering experience and holds ISO9001 and SGS certifications for consistent quality.
Each chain uses 35MnB steel and deep quenching/induction hardening to deliver high hardness and long service life.
Core Selling Points
- Premium 35MnB Material: Track links are forged from 35MnB steel, providing high tensile strength and resistance to cracking under severe bulldozer loads.
- Deep Quenching/Heat Treatment: Pins and bushings undergo deep quenching and induction hardening to HRC 50-55, preventing premature wear and internal friction.
- 100% QC Inspection: Each track chain assembly receives dimensional, hardness, and seal integrity checks before shipment to ensure zero field defects.
- OEM Capabilities: We match John Deere OEM drawings and part numbers, offering custom packaging and private labeling for distribution partners.

Technical Features
Each track chain assembly features precision-forged 35MnB links with induction-hardened wear surfaces, balancing surface hardness with core toughness.
Sealed and lubricated pins and bushings use floating seals to retain oil and exclude abrasive dirt, reducing internal wear.
Deep heat treatment creates a hardened case without brittleness, preventing pin and bushing elongation under high drawbar loads.
Applications
- Mining
- Road Construction
- Quarrying
- Heavy Earthmoving
- Land Clearing
- Forestry

Maintenance Guide
- Inspect track sag daily and adjust tension to John Deere specifications to prevent premature pin and bushing wear.
- Check for oil leakage around seals; replace damaged floating seals immediately to avoid internal wear.
- Monitor link height and bushing diameter; replace chains when wear exceeds factory limits.
- Keep the undercarriage clean by removing debris to prevent excessive abrasion and seal damage.
- Replace chains in complete sets; avoid mixing new and old components to ensure even load distribution.
