1S-4446 Washer
Sealing Washer
Description
A washer is a flat ring made of metal, rubber, or plastic that sits under a nut or bolt head to distribute pressure when tightened or between two joined surfaces.
Features
In a sealed track, there is contact between the internal track pins and bushings, which will result in immediate wear due to friction between the two parts. This significantly increases the internal wear life of the link assembly. The grease-lubricated track link assembly can directly replace the sealed link assembly on Cat Hydraulic Excavators.
