590‑4582 Track Link Assembly — Grease‑Lubricated (GLT / SALT) Undercarriage Chain
The 590‑4582 Track Link Assembly is a core undercarriage chain component for next‑generation Caterpillar 20‑ton excavators. Adopting sealed grease‑lubricated track (SALT/GLT) technology, this 47‑link assembly supports machine weight and provides stable walking guidance. Internal grease lubrication between pins and bushings effectively reduces friction, avoids joint seizure, and ensures reliable performance in complex working conditions.
