Komatsu PC-series mini excavators span many generations and undercarriage configurations. There is no single “Komatsu PC track size,” and several model names appear in catalogs with more than one candidate track identity. The safe approach is to verify the exact machine and molded track marking before ordering.
Why PC-Series Fitment Needs Model-Level Verification
Across the governed TrackTECH catalog, PC-series applications include different widths, pitches, link counts, and guide families. Even closely named machines can differ by generation or configuration. Do not select a track from the “PC” prefix alone.
A Governed Example
The Komatsu PC18MR currently has a cataloged primary TrackTECH fitment of 230x48x70. Other PC-series models may have multiple cataloged or supplier-cross-reference rows, so they still require configuration-specific fitment.
How to Read a Komatsu Track Size
A size such as 300x52.5Nx80 describes width, pitch, guide family, and link count. All four parts matter. Two tracks with the same width can still be incompatible if pitch, links, or guide geometry differ.
How to Verify a PC-Series Track
- Identify the complete model designation, including MR, UU, R, FR, and generation suffixes.
- Read the full molded track marking.
- Match width, pitch, link count, and guide geometry.
- If a model has multiple governed rows, use the installed track and machine configuration to select the correct one.
Do Not Generalize Guide Type Across Komatsu
Some Komatsu excavator applications use N-guide identities while others use different guide families. A brand-level rule is not reliable enough for ordering.

Quick Buying Answers
Which rubber track rides the smoothest? For a verified fitment that offers it, Multi-Bar is usually the first tread to compare when lower vibration and smoother travel matter most.
Which track lasts longest on pavement? On asphalt and other hard, relatively flat surfaces, Multi-Bar is a strong first choice because it spreads contact across more tread bars. For harsher abrasive work such as broken concrete, rock, or demolition debris, compare a heavier C-Block or Staggered Block pattern instead.
What is the best track for paving? Start with Multi-Bar when ride quality, steady contact, and hard-surface travel are priorities. Confirm that the exact pattern is available for your machine before ordering.
What is the most affordable track? Price depends on the exact width, pitch, link count, guide type, and tread. Once fitment is confirmed, compare the live compatible options rather than changing dimensions just to save money.
What about mud, snow, or soft ground? Zig-Zag is usually the better pattern to compare when cleanout and bite matter more than pavement manners.
