What the numbers mean on a Doosan DX30
- 300x52.5Nx84 — 300 mm tread width (about 12"), 52.5 mm pitch, 84 links, narrow guide lugs
Width is the tread face, pitch is the distance between drive lugs, and links is the count around the loop. All three have to match — a track one link off will not tension correctly no matter how close the width is.
Tread choice for the Doosan DX30
Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:
- MX — mixed and hard surfaces. A durable general-duty excavator tread

Tracks. Call for anything not shown online — we can usually source it.
How these wear
Excavator undercarriages load one side hard on slew and travel, so link cracking usually shows up before the tread wears out. Replace in pairs where you can: a new track running against a stretched one loads the drive unevenly and you will feel it in the steering.
Same track, other machines
Track size follows undercarriage geometry, not brand, so 300x52.5Nx84 shows up on machines from several makers. If you run any of these alongside the Doosan DX30, it is the same belt:
- Bobcat E35
- Bobcat E35C
- Bobcat E35Z
- Bobcat E35i
- Ditch Witch MX35
- Doosan DX30Z
- Hanix H36B
- Hanix H36C
- Hanix H36CR
- Hanix H36R
Not sure which you are running? Read the size off the inside of the old track, or call (850) 816-7898 and we will pull it off the machine record. The Track Finder works by make and model too.
