High Strength SK100 Kubota Sprocket Excavator Drive Sprocket OEM

The SK100 Sprocket 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.

SK100 sprockets are primarily used in undercarriage systems of mini or compact excavators (e.g., SK100 series models) to support track movement. They help transmit engine power to the tracks, ensuring smooth operation and reducing slippage.

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
