591-5646 Link Group
Cat® General Duty track links provide versatile, durable, stable, and reliable performance for heavy equipment undercarriage systems.
Description
The link assembly is driven by the sprocket and final drive. It supports the weight of the machine, provides a rail for the machine to travel on, and provides a place for the track shoes to attach.
Features
Grease lubricated tracks have internally lubricated pins and bushings to avoid contact and friction, and each track joint is sealed to keep the grease in. Compared with sealed tracks, this extends internal wear life by 25%, reduces undercarriage noise, and lowers the chance of joints freezing or seizing.
