Description
The link group 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 are designed with internal lubricated pins and bushings to avoid contact and friction; each track joint is fully sealed to prevent grease from escaping. As a result, the internal wear life of sealed tracks can be extended by 25%, undercarriage noise is reduced, and the likelihood of joints freezing or seizing is lower.
