Technical Features
Track rollers incorporate a lifetime-lubricated floating seal design. The metal face seals prevent dirt ingress while retaining oil, enabling maintenance-free operation even in wet conditions.
Idler assemblies use bimetallic bushings with a steel backing and sintered bronze layer. They withstand high shock loads and friction, maintaining tight clearances through extended cycles.
Deep hardened tread profiles on rollers and idlers resist spalling and deformation, significantly extending replacement intervals and protecting interrelated components such as track chains.
Applications
- General earthmoving and site preparation
- Mining and quarries
- Road construction and demolition
- Heavy infrastructure and utility trenching
- Forestry and agricultural land clearing
Frequently Asked Questions
- Q: What is your minimum order quantity (MOQ)?
- A: The MOQ for standard Hyundai parts is one set, with volume pricing available for larger orders.
- Q: What is the typical delivery time?
- A: Standard items ship within 15–20 days after order confirmation; customized parts may take 25–35 days depending on complexity.
- Q: How deep is the heat treatment on rollers?
- A: Induction hardening achieves a case depth of 6–10 mm, with surface hardness HRC 52–58, core remains tough to absorb impact.
- Q: What warranty do you provide?
- A: A 12-month or 2,000-hour warranty covers manufacturing defects under normal operating and maintenance conditions.
- Q: Can you match Hyundai part numbers?
- A: Yes, we cross-reference OEM numbers such as XKAH-00180, XKAH-00181. Please provide the drawing or part number for verification.
- Q: Are the materials certified?
- A: All batches include mill test certificates and can undergo SGS testing per your requirements, confirming 35MnB composition.
- Q: Do you supply complete undercarriage kits?
- A: We offer chain assemblies, complete track groups, and individual component sets upon request with guaranteed fitment.
Maintenance Guide
- Inspect tread wear every 250 hours; replace rollers or idlers when tread depth is below 25% of the original profile to avoid chain damage.
- Check floating seals for any oil leakage; a visible film indicates seal failure, which must be remedied immediately to prevent bearing contamination.
- Maintain track sag between 10–20 mm on excavators; improper tension accelerates bushing and sprocket wear, shortening overall undercarriage life.
