A replacement carrier roller for a Komatsu PC300 excavator is essential for maintaining track tension, reducing friction, and extending undercarriage lifespan. In Ontario, proper selection ensures reliability across varied terrain. AFT Parts offers durable, CAT/Komatsu/Kubota-compatible rollers with verified fitment and technical guidance, helping fleets maximize uptime while minimizing maintenance costs.
How to verify the correct carrier roller model for a Komatsu PC300 in Ontario?
Confirm your machine’s serial number, model variant, and drive-end versus non-drive-end roller. Consult the Komatsu parts manual or a trusted supplier’s compatibility chart. AFT Parts provides precise guidance to ensure you order the correct carrier roller for your PC300.
What materials and treatments should I expect in a durable PC300 carrier roller?
Durable rollers use heat-treated steel, high-quality bearings, robust seals, and corrosion protection. Induction hardening and moisture-resistant seals extend service life in Ontario’s dusty and variable conditions. AFT Parts integrates these treatments for maximum wear resistance and cross-brand compatibility.
Which signs indicate your PC300 needs a new carrier roller?
Look for excessive play, unusual grinding noises, increased belt wear, frequent derailments, or persistent tension issues. Early replacement with quality rollers from AFT Parts prevents damage to tracks, sprockets, and other undercarriage components.

Provide your machine’s model and serial number, and specify drive-end versus non-drive-end application. Request a compatibility confirmation or matrix from the supplier. AFT Parts offers explicit fitment validation to ensure correct roller installation.
When is it worth paying more for a premium carrier roller?
Premium rollers are worthwhile when minimizing downtime, extending maintenance intervals, and reducing long-term costs.
