Technical Features
Single flange design provides stable lateral track guidance while reducing side wear on the track chain during steering and uneven ground operation.
Floating seal assemblies prevent lubricant leakage and block abrasive particle ingress, protecting internal shaft and bushing surfaces in high-load conditions.
Bimetal bushings and hardened shaft surfaces distribute radial loads evenly, improving service life and reducing maintenance frequency.
Applications
- Mining and quarrying
- Road construction
- Demolition and site preparation
- Forestry and land clearing
- Heavy civil earthmoving
Frequently Asked Questions
Q: What is the minimum order quantity for Hyundai bulldozer track rollers?
A: Stock items may be ordered from 1–2 pieces; custom production typically starts at 10 pieces depending on dimension.
Q: What is the delivery time?
A: In-stock rollers ship within 7 working days. Custom production usually takes 25–35 days after drawing confirmation.
Q: How deep is the heat treatment?
A: Surface hardening depth is normally 8–12 mm after deep quenching, with roller tread hardness from 50 to 58 HRC.
Q: What warranty do you provide?
A: We offer a 12-month or 2,000-hour warranty against material and workmanship defects under normal operating conditions.
Q: How do I verify part number compatibility?
A: Provide your Hyundai OEM part number or drawing. Our engineering team confirms dimensions, flange position, and bolt pattern before production.
Q: Can you manufacture single flange rollers for older Hyundai models?
A: Yes, we produce replacement rollers from samples or drawings for various Hyundai bulldozer undercarriage configurations.
Maintenance Guide
- Pre-installation inspection: Check track tension, mounting surfaces, and bolt threads before installing new single flange rollers.
- Torque procedure: Clean all contact areas and tighten mounting bolts sequentially to Hyundai recommended torque values.
- Routine inspection: Every 250 operating hours, check for oil leaks, flange wear, uneven wear patterns, and loose bolts.
- Replacement threshold: Replace rollers when tread surfaces show deep pitting, cracks, or flange wear exceeds the service limit.
- Set replacement: Replace rollers in matched sets or rotate them consistently to maintain even track chain wear and alignment.
