Top Description
Dingtai manufactures complete Samsung track groups, including track chains, shoes, bolts, and nuts, built to support and propel crawler excavators.
We operate factory-direct with full OEM manufacturing services, supplying global dealers, rental fleets, and equipment owners without intermediary markup.
These undercarriage components resist abrasive wear and impact, preventing premature downtime caused by pitch elongation, bushing breakage, and shoe cracking.
Dingtai has over 20 years of production experience and maintains ISO9001 and SGS certified quality systems for consistent dimensional accuracy.
We use 35MnB high-strength steel and deep quench hardening to deliver HRC 52–58 wear surfaces and extended track group life.
Core Selling Points
- 20+ Years Experience: Two decades of undercarriage production for the replacement market ensure proven engineering, stable supply, and reliable field performance.
- Premium 35MnB Material: High-strength boron steel track links and bushings withstand heavy impact loads, reducing deformation and cracking in demanding digging conditions.
- Deep Quenching/Heat Treatment: Induction hardening creates a HRC 52–58 wear layer on bushings and links, improving service life in abrasive ground conditions.
- 100% QC Inspection: Each complete track group is hardness tested and dimensionally checked before packing, preventing installation problems and premature component failure.

Technical Features
Deep quenched bushings create a hardened wear surface that resists internal diameter enlargement, keeping track pitch stable and reducing sprocket jumping.
Forged 35MnB track links provide uniform grain flow and high tensile strength, preventing link rail fatigue and cracking under shock loads.
Sealed and lubricated track chains retain grease between pin and bushing, reducing internal friction, heat, and service intervals.
Applications
- Mining operations with abrasive rock and high-impact loading
- Road construction and highway earthmoving
- Quarrying and aggregate handling
- Demolition and site clearing
- Forestry and land reclamation
- Heavy civil engineering and pipeline projects
Frequently Asked Questions
What is the MOQ for Samsung track groups?
One complete track group per model is accepted. Mixed specifications can be consolidated into one shipment.
What is the delivery time?
Standard production is 15–25 days after deposit confirmation, depending on model and order quantity.
What heat treatment depth do you guarantee?
Track bushings and links are induction hardened to HRC 52–58 with a hardened layer depth of 4–8 mm.
What warranty do you provide?
12 months or 2,000 operating hours from shipment date, covering manufacturing defects under normal operating conditions.
Can you match Samsung part numbers?
Yes. Provide the original part number or drawing; we cross-check dimensions and supply exact OEM specification.
Do you supply complete track groups or individual parts?
We supply factory-assembled complete track groups and individual track chains, shoes, bolts, and nuts.
What packing methods do you use?
Undercarriage parts are anti-rust treated and secured on steel pallets or wooden cases for safe container or LCL shipping.
Maintenance Guide
- Check track sag weekly and adjust tension; incorrect tension accelerates bushing and sprocket wear.
- Tighten shoe bolts after the first 50 operating hours, then inspect torque every 250 hours.
- Monitor bushing outer diameter and shoe grouser height; replace at 30% material loss.
- Clean clay, rock, and debris from undercarriage daily to prevent packing and link fatigue.
- Rotate track groups side-to-side every 1,500 hours to balance pin and bushing wear.
