Factory Price PC60 Lug-Pattern Excavator Idler Assy Front Idler for 6-Ton Komatsu PC60-Series

The PC60 Idler Assy is Kubota's compact powerhouse component designed for excavators in demanding Australian projects. This precision-engineered bottom roller ensures durability, excellent load-bearing capacity, and smooth operation in compact construction machinery.

The PC60 Idler Assy (short for "idler assembly") is a vital wear part in the undercarriage system of Komatsu PC60 series excavators. It plays a central role in maintaining track alignment, reducing friction between the track chain and other undercarriage components, and supporting the excavator's weight during tasks like digging, pushing, and traversing rough terrain. Proper maintenance of the idler assembly is essential to minimize downtime and extend the lifespan of the undercarriage.
