Track bushings, along with the pins, hold the track links together and are part of the sealing arrangement between the link and the bushing.
Grease Lubricated Track features internally greased pins and bushings to eliminate contact and friction, each track joint sealed to retain the grease. This improves internal wear life by 25% over sealed track, decreases undercarriage noise and reduces the potential of frozen or seized joints.
