    Sealed Link Assembly (Two Piece Belleville Washer)


    • Link assemblies, driven by the sprocket and final drive, provide support for the machine weight, a rail for the machine to run on, and a place for the shoes to attach.


    • Sealed track has contact between the internal pin and bushing causing wear to begin immediately because of the friction between the two parts. This results in a significant increase of internal wear life of the link assembly. Grease Lubricated Track link assemblies are direct replacements for sealed link assemblies on Cat Hydraulic Excavator models.
    • Belleville washers are springs shaped like a washer. They are used in Sealed Track to help keep the system sealed.
