Komatsu idlers help keep your equipment moving smoothly, guiding the tracks and supporting the undercarriage across excavators, bulldozers, and other heavy-duty machines. Engineered for compatibility across a wide range of Komatsu models, these undercarriage parts help maintain track tension and alignment, ensuring stable machine performance in challenging job sites.
- Manufactured from high-strength alloy steel, Komatsu aftermarket idlers offer superior resistance to wear and corrosion.
- The bronze bushings are CNC-machined for high dimensional accuracy, enhanced durability, and thermal stability.
- Each idler is produced in strict accordance with OEM specifications, with 1:1 dimensional precision.
- Available for Komatsu machines ranging from 20-ton excavators to 300-ton mining excavators and 100-ton bulldozers.

Is this Komatsu aftermarket idler compatible with my heavy equipment model?
Is this Komatsu aftermarket idler compatible with my heavy equipment model?
Yes, we supply idlers for various Komatsu models from 20-ton and 30-ton excavators to 80-ton and ultra-large 300-ton mining machines. You can verify compatibility by matching your OEM part number or confirming dimensions via technical drawings.
What materials are used in Komatsu aftermarket idlers?
What materials are used in Komatsu aftermarket idlers?
We use premium alloy steel such as 35SiMn for the idler body and 42CrMo forged steel for the shaft. Components undergo surface hardening up to HRC 55–58 to ensure durability in high-impact environments like mining, quarrying, and coal excavation.
How do these idlers perform in heavy-duty and mining operations?
How do these idlers perform in heavy-duty and mining operations?
Thanks to high-strength material selection, precision manufacturing, and thorough heat treatment, our idlers withstand high-load, high-dust, and high-shock conditions with consistent wear resistance and extended service life.
Can I replace only the idler without changing the entire undercarriage?
Can I replace only the idler without changing the entire undercarriage?
Yes, idlers can be replaced independently as long as other undercarriage components remain in good condition.
Do you offer bulk purchasing and fleet maintenance support?
Do you offer bulk purchasing and fleet maintenance support?
Absolutely, we provide competitive pricing for bulk orders and streamlined after-sales support. This helps reduce equipment downtime in large-scale mining or construction projects and ensures efficient maintenance across machine fleets.
What cleaning is required for Komatsu undercarriage systems?
What cleaning is required for Komatsu undercarriage systems?
After daily operations, it’s essential to remove accumulated dirt, sand, and gravel from the tracks, carrier rollers, track rollers, and sprockets. Pressure washing key components helps reduce abrasive wear caused by embedded debris.
How often should I lubricate the Komatsu undercarriage?
How often should I lubricate the Komatsu undercarriage?
Proper lubrication is critical to minimizing friction and maximizing lifespan. Follow Komatsu's maintenance schedule and use suitable lubricants such as GL-5 140-grade gear oil or equivalent for optimal results.
Should track tension be adjusted in rocky or uneven terrain?
Should track tension be adjusted in rocky or uneven terrain?
For areas with excessive gravel or rough terrain, slightly loosening the track tension can improve flexibility and reduce the risk of obstruction. Be sure to clean out any debris after operation to prevent buildup that can affect performance.
