Factory Price D10 Lug Pattern Excavator Track Roller Bottom Roller Exact Fit for Komatsu D10 Bulldozers

The D10 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 D10 track roller is a specialized undercarriage part designed exclusively for Caterpillar D10 bulldozers, serving as a foundational element in the machine’s track system. Its primary role is to support the bulldozer’s full operating weight, absorb severe ground shocks from rough terrain (e.g., rocks, mud), and minimize operational resistance—contributing to over 70% of the machine’s overall resistance.

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
