2S-0253: Bushing

Description: Track bushings, along with the pins, hold the track links together and are part of the sealing arrangement between the link and the bushing. 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.
