W (Wide Guide) |
Manufactured using Continuous Cord Technology. The W designation indicates wide guide lugs, providing stable support on rollers in machines with internal guiding. The increased track weight (approx. 10%) translates to better traction and longer service life.
Key Technical Advantages:
- Type W (Wide Guide): Wide guiding prevents track derailment and works perfectly with widely spaced rollers (e.g., in CAT 304/305 series).
- Reinforced Structure: Thickened, twisted steel reinforcements increase tensile strength.
- Pro-Edge Technology: Enhances track edge durability, protecting it when maneuvering in difficult terrain.

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 W and N versions?
The W (Wide) symbol designates wide internal guiding. This is crucial for the machines listed above (e.g., CAT 305 or Kubota KX161), which have wide roller spacing. The N (narrow) version is designed for a different type of undercarriage.
Does it fit Takeuchi TB145?
Usually not. The Takeuchi TB145 typically requires a N (Narrow) track with 74 links (check our product 400x72.5x74N). Here we offer the W version with 72 links, which fits models like the TB55UR.
