N (Narrow Guide) |
Manufactured using Continuous Cord Technology. The N designation indicates narrowed guide lugs. This is a critical parameter for the machine models listed below – using a wide (W) version may lead to roller damage.
Key Technical Advantages:
- Type N (Narrow Guide): Precisely matched to track rollers in machines like Hitachi ZX40/50 or Komatsu PC50MR.
- Reinforced Weight: Arisun tracks are approx. 10% heavier than standard aftermarket options, translating to thicker tread and solid steel cord.
- Pro-Edge Technology: Optimized side edges reduce the risk of mechanical damage when climbing obstacles.

Service Tip: When installing a new track, always inspect the undercarriage. Running a new track on a worn
drive sprocket or damaged idler will drastically shorten the track's lifespan.
Frequently Asked Questions (FAQ)
What is the difference between N and W versions?
The N (Narrow) symbol indicates narrow internal guiding. This is crucial for the machines listed above (e.g., Hitachi ZX50U), which have a narrower roller spacing than, for example, Bobcat machines (which require the W version).
Does it fit Takeuchi TB145?
Yes, the Takeuchi TB145 is listed as compatible for the N version. However, we always recommend checking the marking on your old track, as some model years might have undercarriage variations.
