Top Description
Dingtai manufactures Hyundai track adjust assemblies, hydraulic tension cylinders that keep excavator tracks correctly tensioned and centered during operation.
We operate as a factory-direct supplier with complete OEM manufacturing services, supporting distributors, dealers, and fleet owners worldwide.
This assembly prevents premature track wear, derailment, and idler damage by holding consistent tension under shock loads and abrasive conditions.
With over 20 years of undercarriage manufacturing experience and ISO9001/SGS-certified processes, Dingtai delivers repeatable quality and dimensional accuracy.
Key components use forged 35MnB steel, deep quenching, and hard chrome plating to resist deformation, scoring, and seal wear.
Core Selling Points
- 20+ Years Experience: Dingtai has produced heavy machinery undercarriage components for over two decades, supplying mature engineering solutions to demanding international markets.
- Global Brand Compatibility: Hyundai track adjust assemblies are manufactured to match OEM mounting dimensions and hydraulic interfaces for popular R-series excavators.
- Premium 35MnB Material: Main cylinder bodies and rods use forged 35MnB steel, offering high tensile strength and better fatigue resistance in rocky terrain.
- Deep Quenching/Heat Treatment: Induction hardening and deep quenching deliver a wear-resistant cylinder bore and piston rod surface with consistent hardness depth.

Delivery & Logistics
We ship factory-direct worldwide with flexible MOQs, export-grade packing, and reliable sea or air freight. Standard lead time is 15–30 days.
Technical Features
The track adjust assembly is a grease-charged hydraulic cylinder. Grease pressure extends the piston, moving the idler forward to maintain precise track sag.
A calibrated relief valve vents excess grease during extreme impacts, preventing over-tension that can damage final drives and idler bearings.
Hard chrome-plated rods and induction-hardened cylinders reduce friction and seal wear, extending service intervals in abrasive operating environments.
Applications
- Mining: Handles continuous rock impacts and heavy bucket loads without track tension loss.
- Road Construction: Maintains stable track sag during long travel cycles on graded surfaces.
- Quarrying: Resists abrasive stone dust and high-frequency shock loads in crushing areas.
- Demolition: Withstands debris impacts and frequent reverse travel on unstable ground.
- Forestry: Operates reliably on uneven, stump-filled terrain with high lateral stress.
Frequently Asked Questions
What is the minimum order quantity?
MOQ is 1–5 units depending on the Hyundai model. Sample orders are accepted for first-time clients.
What is the standard delivery time?
Standard production takes 15–30 days. In-stock assemblies ship within 7 working days.
What heat treatment depth is used?
Cylinder bores are hardened to 2–4 mm depth at 50–55 HRC; piston rods receive 20–30 µm hard chrome plating.
What warranty policy applies?
12 months or 2,000 operating hours against manufacturing defects, whichever comes first.
Can you match Hyundai part numbers?
Yes. Send the OEM part number or drawing; we cross-reference dimensions and hydraulic interfaces before quotation.
Are these genuine Hyundai parts?
No. Dingtai supplies aftermarket replacements engineered to OEM performance standards.
Do you offer custom dimensions?
Yes. We manufacture to customer drawings, including non-standard mounting and cylinder lengths.
Maintenance Guide
- Installation: Clean mounting bores, align idler yoke, and grease cylinder until track sag matches OEM specification.
- Inspection: Check piston rod for scoring, seal leakage, and relief valve function every 250 hours to detect early failure.
- Adjustment: Pump grease only to recommended track sag; over-tensioning accelerates idler and final drive wear.
- Replacement: Replace assembly when cylinder bore is scored, chrome is flaking, or tension cannot be maintained.
