If you’ve ever ordered replacement rubber tracks and felt like you were reading a secret code, you’re not alone.
Numbers and letters at the end of a rubber track code might seem confusing at first, but once you know what they mean, they can tell you everything from size and style to machine compatibility. In our blog, we’ll decode those cryptic codes and help you make the right choice every time.
Why Rubber Track Codes Matter
Every rubber track is built to suit specific machine sprockets, rollers and idlers. Choosing the right one isn’t just about size. It’s about performance, longevity, safety, and cost. Those digits and letters help you match your machine with the right track, ensuring better traction, less downtime, and a smoother experience on-site.
Let’s break it down.
What Each Number Means
What Do Those Letters Mean?
Now for the fun part: those extra letters at the end of the code. These aren’t random. They tell you how the track is guided and sometimes what machine it suits.
Here’s a cheat sheet:
- W = Wide Guide
Indicates a wide guiding system. Designed to work with machines that need broader guide lugs for better roller engagement. - K = Guide with Plates / Outside Guided
This means the guiding plates sit on the outside of the track, so your rollers run along the edges, not in the centre. - Y = Offset Centred Guide
The guiding lugs are offset from the centreline. This often matches specific undercarriage layouts where traditional guides won’t work. - B = Bobcat Compatible
Made to suit Bobcat machines. You might also see other OEM prefixes I.e.: T for Takeuchi, C for Case, and so on.
These markers are key for compatibility, especially when ordering for mixed fleets or grey imports.
Why Manufacturer Variations Matter
Each OEM might tweak these codes to suit their machines. That’s why two tracks of the same size can still be incompatible.
Takeaway? Always match both the measurements and guide type to your machine’s make and model, alternatively, give us a shout and we’ll help you sort it.
Common Misconceptions
“It’s just a rubber track, how different can they be?”
Actually, very different. Choosing a track with the wrong pitch or guide system will more than likely not fit or if fitted could possibly damage your undercarriage components and cause excessive wear, or worse, void your warranty.
“As long as it fits, it’ll work.”
Fitting is just one part. The wrong type can lead to poor floatation, slippage, reduced performance and damage to your machine
Choosing the Right Rubber Track: Your Next Steps
Here’s what you’ll need before ordering:
✅ Track width
✅ Pitch (distance between guide lugs)
✅ Number of links
✅ Guide system (W, K, Y, etc.)
✅ Machine make and model

Frequently Asked Questions
How can you tell if rubber tracks are bad?
Look for these signs your tracks are past their prime:
- Cracks, cuts or chunking in the rubber
- Exposed steel cords where the Track Steel belting is exposed outside the Track
- Stretched links or missing drive lugs
- Constant de-tracking
- Poor traction or a rough ride
If you spot any of these, it’s time to replace them—before they damage your machine.
How to find rubber track size?
You can usually find the track size stamped on the inside of the track, or in your machine’s manual. If not, measure:
- Track width (mm)
- Pitch (distance between lugs)
- Total number of links
Or just call us, we’ll help you size it up fast.
How to identify track size?
The best way is to check your existing track’s markings or your equipment manual. If unavailable, you can measure:
- Width of the rubber track (edge to edge)
- Pitch (centre of one lug to the next)
- Count the total number of lugs
These three figures make up your rubber track code.
How to choose the right rubber tracks for a mini excavator?
Start with the track code—width, pitch, and link count are key. Then check the guide system (like W, K, Y) to make sure it suits your undercarriage. Also consider your terrain and workload.
Not sure? Give us a call, we stock rubber tracks to suit all major brands and conditions across Australia.
What are the advantages of rubber tracks for a mini excavator?
Rubber tracks offer:
- Less ground disturbance / damage than steel
- Smooth travel on hard surfaces
- Lower noise levels
- Better floatation on soft ground
- And they’re easier to replace and maintain
Perfect for tight access sites, landscaping, and urban work zones.
