   • Produced by the original manufacturer of the excavator.
   • Designed specifically for the model of the excavator.
   • Generally higher in price but offer guaranteed quality and compatibility.
2. Aftermarket Parts:
   • Manufactured by companies other than the original manufacturer.
   • Can often be cheaper, but quality may vary widely.
   • May provide good alternatives but can lack the exact specifications of OEM parts.
