Top Description
We manufacture Samsung track cylinder pistons, precision hydraulic components that convert oil pressure into mechanical force within excavator track tension cylinders.
Factory-direct production supports OEM and aftermarket supply with full machining, heat treatment, and dimensional inspection for global equipment buyers.
This piston resists scoring and seal failure, preventing track cylinder leakage, loss of tension, and unplanned undercarriage downtime.
Dingtai has over 20 years of engineering experience and holds ISO9001/SGS certifications, ensuring repeatable quality and traceability.
Premium 35MnB steel and deep induction quenching deliver a hardened wear surface for extended service life under high-pressure cycles.
Core Selling Points
- 20+ Years Experience: Two decades of excavator cylinder component production ensure mature processes, reliable supply, and OEM-level technical support for demanding procurement teams.
- Global Brand Compatibility: Direct replacement for Samsung SE and MX series track cylinders, matching OEM dimensions, seal grooves, and hydraulic interface specifications.
- Premium 35MnB Material: High-strength boron alloy steel improves fatigue resistance and load-bearing capacity, reducing cracking and deformation in severe track tension applications.
- 100% QC Inspection: Every piston is dimensionally checked, hardness tested, and surface-finished to prevent premature seal wear and hydraulic leakage.

Technical Features
The piston converts pressurized hydraulic oil into linear force. Precision-ground outer diameters maintain seal contact, preventing internal bypass and pressure loss.
Induction quenching creates a hard martensitic layer on the wear surface while retaining a tough core, reducing scoring under contaminated oil conditions.
Tight concentricity and chromium-based surface treatment minimize seal abrasion, extending track cylinder service intervals in high-cycle applications.
Applications
- Mining
- Road Construction
- Quarrying
- Heavy Earthmoving
- Demolition
- Forestry
Frequently Asked Questions
What is the minimum order quantity for Samsung track cylinder pistons?
Minimum order quantity is typically 10 pieces for stock dimensions. Smaller trial orders are available for OEM verification.
How long is delivery time?
Standard production takes 15–25 days after drawing confirmation. Stock samples ship within 7 days.
What heat treatment depth do you apply?
Induction hardening depth is normally 1.5–2.5 mm, with surface hardness HRC 50–55 depending on material grade.
What warranty policy applies?
We provide 12 months against material and manufacturing defects under normal operating conditions.
Can you match original Samsung part numbers?
Yes, provide the OEM part number or drawing. Our engineers cross-check dimensions and seal groove geometry.
Do you offer custom packaging or private labeling?
Neutral packaging, branded boxes, and custom labeling are available for qualified OEM customers.
Maintenance Guide
- Clean cylinder bore and piston grooves completely. Check for nicks, burrs, or contamination before assembling new seals.
- Replace pistons if hard chrome shows scoring, pitting, or diameter wear beyond OEM tolerance limits.
- Inspect track cylinder piston at every 2,000 operating hours or when track tension drops repeatedly.
- Use specified hydraulic oil and replace filters to prevent particle contamination that accelerates piston and seal wear.
