What the numbers mean on a Bobcat 331E

  • 300x52.5Nx80 — 300 mm tread width (about 12"), 52.5 mm pitch, 80 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 Bobcat 331E

Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:

  • Directional — digging, trenching and slope work. The standard excavator tread

Undercarriage parts for the Bobcat 331E

Rollers, idlers and sprockets wear on the same clock as the track. Fitting new rubber over a hooked sprocket or a seized roller is the fastest way to lose the new track — check these while the tracks are off:

Where more than one part number is listed, Bobcat changed that component across serial ranges. Match the number stamped on the part you are replacing, or send us the machine serial and we will pick 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 300x52.5Nx80 shows up on machines from several makers. If you run any of these alongside the Bobcat 331E, it is the same belt:

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.

  • 100% Virgin Rubber

    Engineered to resist chunking, tearing, and cutting in harsh, abrasive environments.

  • Continuous Steel Cords

    Jointless internal cable architecture eliminates structural weak points and maximizes overall tensile strength.

  • Drop-Forged Links

    Precision heat-treated guide lugs ensure exact sprocket engagement and prevent de-tracking under heavy side-loads.

  • Corrosion Resistant

    The internal steel framework is fully encapsulated to prevent oxidation, rust, and moisture penetration.

  • Reinforced Sidewalls

    Extra-thick vulcanized rubber and tapered edge profiles protect against curb slashing and lateral impacts from jobsite debris.

  • Low-Vibration Tread

    Optimized lug spacing and pitch geometry absorb shock, reducing undercarriage wear and minimizing cabin vibration.
