Komatsu CK30 Rubber Tracks & Parts

The Komatsu CK30 runs a 450x86x56 track: 450 mm across the tread, 86 mm between links, 56 links around. Cut for grading, loading, pallet work and land clearing and shipped free to the lower 48.

What the numbers mean on a Komatsu CK30

  • 450x86x56 — 450 mm tread width (about 18"), 86 mm pitch, 56 links

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 Komatsu CK30

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

  • All-Terrain — everything in between. A compromise tread when the machine moves between surfaces
  • Staggered Block — mixed dirt and gravel. Block stability with better cleanout than a straight block
  • C-Block — concrete, asphalt and hard-packed ground. Longest wear life and the least vibration on hard surfaces
  • Multi-Bar — mud, snow and soft ground. Deep bar lugs bite and shed material instead of packing up
  • X-Terrain — the worst ground you have. Aggressive lugs for mud, slope and loose fill
  • Z-Max — soft and slippery ground. An aggressive zig-zag with more bite

If the machine splits its time between surfaces, buy for the ground you are on most — a hard-surface tread on constant mud will spin, and a bar tread on concrete will wear out in half the hours.

Undercarriage parts for the Komatsu CK30

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:

How these wear

CTLs run high ground speed and counter-rotate all day, which is what eats edge lugs and drive lugs first. 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 450x86x56 shows up on machines from several makers. If you run any of these alongside the Komatsu CK30, 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.
