SK100 Excavator Drive Sprocket OEM Fit 8-Bolt Lug Pattern

The ​​SK100 sprocket​​ is a standardized track sprocket commonly used in ​​mini excavator undercarriage systems​​, designed to guide and tension tracks for optimal power transfer and stability. It is a critical wear component that ensures smooth operation of the track drive system, preventing slippage and misalignment.The SK100 sprocket is primarily engineered for the ​​SK100-series mini excavators​​ from Sany Heavy Industry. However, its compatibility extends to other brands/models with similar track pitch (100mm) and sprocket dimensions.The SK100 sprocket is ​​engineered specifically for SK100-series mini excavators​​ (e.g., SK100-1, SK100-3, SK100-5). While it may fit other mini excavators with similar track pitch (100mm) and sprocket dimensions, compatibility is not guaranteed for non-Sany models (e.g., Hitachi, Komatsu) or larger excavators.
