Dingtai manufactures Hyundai track cylinder pistons, precision components driving hydraulic track adjuster force and maintaining correct excavator track tension.
Factory-direct production provides comprehensive OEM manufacturing services for distributors and equipment fleets, removing intermediaries and controlling total cost.
Our pistons resist scoring, galling, and seal failure, preventing hydraulic leaks and track tension loss that cause premature undercarriage wear.
With over 20 years of engineering experience and ISO9001/SGS certified processes, Dingtai delivers repeatable quality for demanding heavy equipment applications.
Each piston uses premium 35MnB steel, precision CNC machining, and deep quenching heat treatment to achieve high hardness and extended service life.
Core Selling Points
- Global Brand Compatibility: Direct replacement for Hyundai track tension cylinders; supports R55, R80, R210, R220, R300 and similar excavator and bulldozer platforms.
- Premium 35MnB Material: Forged from 35MnB alloy steel for stronger tensile strength and improved impact resistance in high-pressure track adjuster applications.
- Deep Quenching/Heat Treatment: Induction hardening with deep quenching delivers consistent HRC52–58 surface hardness, reducing galling and seal abrasion under heavy load.
- OEM Capabilities: We manufacture to Hyundai drawings or reverse engineer samples, offering custom dimensions, private labeling, and strict OEM tolerance compliance.

Technical Features
Track cylinder pistons convert hydraulic or grease pressure into linear idler movement, maintaining accurate track sag under digging, steering, and reverse loads.
Precision-ground sealing grooves and polished contact surfaces reduce internal leakage and seal drag; hardened 35MnB body withstands cyclic pressure spikes and side loading.
Tight geometric tolerance prevents piston binding and uneven seal wear, extending cylinder rebuild intervals in severe undercarriage conditions.
Applications
- Mining
- Road Construction
- Quarrying
- Demolition
- Heavy Civil Infrastructure
- Forestry
Frequently Asked Questions
1. What is the MOQ for Hyundai track cylinder pistons?
Standard MOQ is 10 pieces. Evaluation sample orders may be accepted for first-time buyers.
2. What is the delivery time?
In-stock specifications ship within 7–10 days. Custom production normally takes 25–35 days depending on quantity.
3. What heat treatment depth do you achieve?
Induction hardening depth is 1.5–3.0 mm based on piston OD, achieving HRC52–58 surface hardness.
4. What warranty is provided?
We provide a 12-month warranty from shipment against material and manufacturing defects under normal operating conditions.
5. Can you match Hyundai OEM part numbers?
Yes. Provide a Hyundai part number or drawing, and we confirm the exact cross-reference and critical dimensions.
6. Do you support custom coating or dimensional changes?
Yes, we offer hard chrome plating, nitriding, and custom machining for non-standard track tension cylinder pistons.
7. Do you provide inspection reports?
Yes, each order includes dimensional reports, hardness test records, and SGS material certification when required.
Maintenance Guide
- Installation: Clean cylinder bore and install piston with new seals; apply clean grease or approved hydraulic oil to prevent dry startup.
- Inspection: Check piston surface for scratches, pitting, or chrome loss every 1000 operating hours; replace if scoring exceeds 0.15 mm.
- Pressure Check: Verify track tension cylinder pressure; over-tensioning accelerates piston and seal wear.
- Replacement: Replace piston and seals together when internal leakage or track creep appears; never mix new pistons with worn seals.
