Samsung excavator undercarriage parts comprise track rollers, idlers, sprockets, and track chains. They form the travel base, supporting machine weight and enabling mobility.
Direct from our ISO9001 factory, we provide comprehensive OEM manufacturing services for global clients. Every component meets rigorous Samsung undercarriage specifications without middleman markups.
These precision-built parts prevent catastrophic undercarriage failures, resist abrasive wear in harsh ground conditions, and eliminate costly unplanned downtime on critical projects.
With over 20 years of specialized manufacturing experience and SGS-verified quality systems, we deliver proven reliability. Our certifications guarantee consistent material integrity and dimensional accuracy.
We forge key components from 35MnB steel and apply deep induction hardening to HRC52-58. This process creates a wear‑resistant case with a tough, fracture‑proof core for extreme service life.
Core Advantages
- Global Brand Compatibility: Engineered as direct replacements for Samsung SE series excavators. Drop‑in fitment eliminates modification, preserving OEM track frame geometry and mounting tolerances.
- Premium 35MnB Material: High‑strength boron steel forgings offer superior hardenability and impact toughness. The microstructure resists rolling contact fatigue and surface spalling under heavy loads.
- Deep Quenching & Heat Treatment: Computer‑controlled induction hardening penetrates 8–12 mm, achieving a consistent HRC52-58 case depth. Core remains ductile, absorbing shock without cracking.
- ISO9001/SGS Certified: Every production batch undergoes dimensional and hardness verification. Certification ensures traceability from raw material heat number to finished component, meeting global procurement standards.
Our catalog of Samsung Excavator Undercarriage Parts includes various specifications, fully compatible with Samsung excavators and bulldozers.

Technical Features
Floating seal technology utilizes a pair of precision‑lapped metal rings and O‑rings. This creates a zero‑leak dynamic barrier that keeps lubricating oil in and abrasive soil, water, and sand out, extending internal bearing life dramatically.
Bimetal bushings combine a steel backing with a sintered bronze alloy layer. The structure offers high load capacity with self‑lubricating properties, reducing friction and galling under oscillating motions that typify track chain pivots.
Deep quenching transforms the surface layer to martensite while maintaining a pearlite‑ferrite core. This gradient provides a hard wear surface that withstands abrasive rock while the core absorbs impact energy without fracturing.
Applications
- Open‑pit mining and mineral extraction
- Heavy civil construction and infrastructure
- Quarrying and aggregate processing
- Road building and railway ballast spreading
- Demolition and site remediation
- Forestry and land clearing
Frequently Asked Questions
- What is the minimum order quantity for Samsung undercarriage parts?
- Standard MOQ is 2 metric tons. For first‑time trial orders, we can supply smaller quantities of high‑volume rollers or idlers to build trust.
- How long does delivery to the United States take?
- Production lead time is 15–20 days, and ocean freight to major US ports adds 20–30 days. Air freight is available for urgent breakdown orders.
- What heat treatment depth do you guarantee on rollers and idlers?
- The induction‑hardened case depth is consistently 8–12 mm, verified by ultrasonic testing. This exceeds many aftermarket alternatives and matches OEM specifications.
- What warranty comes with your Samsung undercarriage parts?
- We provide a 12‑month or 2000‑hour warranty against manufacturing defects. This does not cover misuse, lack of maintenance, or track tension abuse.
- Can you supply parts using original Samsung part numbers?
- Yes. Simply provide the genuine Samsung part number or share a sample drawing. We cross‑reference to manufacture direct‑fit components with zero modification required.
- Do you offer customized packaging or private labelling?
- Absolutely. We can apply your corporate logo and use neutral or branded packaging. OEM branding and full crate documentation are standard services.
Maintenance Guide
- Inspect Seals: Check rollers and idlers weekly for oil leakage. Wetness around the flange indicates floating seal failure—replace immediately to avoid internal contamination.
- Adjust Track Tension: Maintain proper sag (typically 20–30 mm for Samsung SE models). Over‑tensioning accelerates pin/bushing wear; under‑tensioning can cause derailment.
- Measure Wear Limits: Use callipers to track tread surface wear. Replace components when the case‑hardened layer is consumed—visible deformation or cracking occurs beyond safe limit.
