Description
The Cat® link group is driven by the sprocket and final drive, supports the weight of the machine, provides a rail for the machine to travel on, and provides a location for attaching track shoes.
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.
