Dingtai manufactures Samsung track link assemblies, critical undercarriage components connecting track shoes and transferring machine weight for stable excavator operation.
We provide factory-direct supply and OEM manufacturing services for Samsung undercarriage components to global equipment distributors and end users.
Our heat-treated track links prevent premature wear, elongation, and link breakage, reducing unplanned downtime in demanding earthmoving applications.
With over 20 years of undercarriage manufacturing experience and ISO9001/SGS certified processes, Dingtai delivers repeatable quality for heavy equipment fleets.
Each link uses 35MnB steel and deep quenching technology to achieve surface hardness and extended service life under impact loads.
Core Selling Points
- Premium 35MnB Material — Forged from high-strength 35MnB alloy steel, our links resist tensile stress and elongation, ensuring reliable performance in abrasive conditions.
- Deep Quenching/Heat Treatment — Deep quenching and tempering produce uniform hardness distribution across the rail and pin bore, reducing wear and crack formation.
- OEM Capabilities — We manufacture to OEM drawings or sample reverse engineering, matching pitch, pin diameter, and bolt patterns for direct replacement.
- 100% QC Inspection — Every assembly passes dimensional checks, magnetic particle testing, and hardness verification before packaging to ensure zero-defect delivery.
Our catalog of Samsung Track Link Assembly includes various specifications, fully compatible with Samsung SE series excavators and bulldozers.

Technical Features
Track links transmit machine weight and drive force. Precision forged 35MnB steel provides high tensile strength and elongation resistance.
Press-fitted pins and bushings create a sealed joint. Optional lubricated designs retain oil and exclude abrasive dirt, extending service intervals.
Induction hardened rail surfaces reduce wear at the idler and sprocket contact zones, preserving track pitch and reducing vibration.
Applications
- Mining
- Road Construction
- Quarrying
- Demolition
- Heavy Civil Works
- Earthmoving
Frequently Asked Questions
Q: What is minimum order quantity for Samsung track link assemblies?
A: MOQ is usually one full set per model. Mixed models are accepted for first trial order to support evaluation.
Q: How long is delivery time?
A: Regular Samsung models ship within 15–25 days after deposit. Custom OEM orders require 30–45 days depending order quantity.
Q: What heat treatment depth do you achieve?
A: Rail surface hardness depth typically reaches 8–15 mm after deep quenching, depending link section and OEM specification.
Q: What warranty do you provide?
A: 12 months or 2,000 working hours, whichever comes first, against material and manufacturing defects under normal use.
Q: Can you match OEM part numbers?
A: Yes, provide your Samsung part number or drawing. We cross-reference dimensions and confirm compatibility before production.
Q: Do you offer samples?
A: One sample set is available for evaluation. Freight is collect or negotiable depending project potential.
Q: What material do you use?
A: Premium 35MnB alloy steel is standard. 40Mn2 is optional for heavier impact and higher load applications.
Maintenance Guide
- Check track link pitch elongation every 500 working hours; replace links if pitch exceeds OEM wear limit.
- Inspect pins and bushings for wear and oil leakage; rotary or replacement is needed if radial play exceeds 3–5 mm.
- Maintain correct track tension according to Samsung specifications to reduce sprocket and link contact stress.
- Clean undercarriage after operation; remove abrasive debris to prevent accelerated link, pin, and bushing wear.
- Replace track link assemblies in pairs or full sets to maintain equal chain tension and undercarriage alignment.
