Description:

• Seals maintain lubrication and keep dirt and other contaminants from entering into the pin and bushing cavity.

Attributes:

• 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.
