The PC20 High-Side Mini Track Roller 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 PC20 high-side mini track roller is a specialized wear part designed for the undercarriage system of Komatsu mini excavators, primarily tasked with supporting the upper run of the rubber track. It plays a vital role in reducing friction between the track and machine frame, ensuring smooth movement and even weight distribution during excavation, grading, and other light-duty tasks. As a load-bearing component, it must withstand significant vertical and horizontal forces from the track, making durability and precision essential to preventing track slippage, uneven wear, and costly downtime.

Our production involves rigorous quality-controlled processes:

• High-grade Material Selection: Components are crafted from premium materials for maximum durability
• Outer Race/Shell: High-carbon chromium bearing steel (SUJ2) for superior hardness and wear resistance
• Inner Roller/Spindle: Alloy steel (SCM440) engineered to withstand significant radial and axial loads
• Seals & Lubrication: Nitrile rubber (NBR) seals for oil resistance with lithium-based grease for long-term lubrication
• Quality Assurance: All materials undergo thorough inspection for chemical composition and mechanical properties using spectrometers and hardness testers
