Factory Price D65-2 Lug Pattern Excavator Idler Assy Front Idler Assembly 65-30-00020

The D65-2 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 D65-2 Idler Assy (short for "idler assembly") is a vital wear part in the undercarriage system of Komatsu D65-2 excavators, designed to work in conjunction with track chains, sprockets, and rollers to ensure smooth track movement. Its primary functions include guiding the track chain along its correct path, reducing friction between moving 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.

Our production involves rigorous quality-controlled processes:
