The Hitachi EX20UR-3 is listed with more than one build of the same 300 mm track. Match link count to what is on the machine now. Free freight to the lower 48, 24-month warranty.
Hitachi EX20UR-3 track options
- 300x52.5Nx78 — 300 mm (12") wide, 52.5 mm pitch, 78 links, narrow guide lugs
- 300x52.5x76 — 300 mm (12") wide, 52.5 mm pitch, 76 links
Same tread width on all of them — what changes is pitch and link count, which is set by the sprocket and roller frame. Read the numbers off the inside of the old track rather than going by model year; these were built across more than one undercarriage spec.
Tread choice for the Hitachi EX20UR-3
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 one of these sizes shows up on machines from several makers. If you run any of these alongside the Hitachi EX20UR-3, it is the same belt:
- Airman AX20-3
- Airman AX20UR
- Airman AX25-2
- Bobcat E25
- CAT MM25T
- Case CX20B
- Case CX20BMR
- Case CX22B
- Case CX22BMC
- Case CX22BZTS
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.
