Roller Track Excavator MM45 Single Double Flange

The MM45 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.Mini track rollers are critical components in excavator undercarriages, supporting the chassis and distributing the machine’s weight to reduce ground pressure. They are typically made of die-cast iron, cast steel, or welded steel plates, ensuring high load-bearing capacity and durability. Common models include KH010, KH025, KX16, and KX161, manufactured by companies like STARKEA.

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
