Product Description

D20 Bulldozer Undercarriage Track Link Assembly - Oil-Sealed Heavy-Duty Track Chain Group

Track Link Features

Engineered to eliminate track link failures that stall operations and inflate costs, our components deliver superior performance and reliability.

We utilize advanced machining centers and horizontal/vertical CNC equipment for turning, drilling, threading, and milling operations, ensuring top-tier quality, precision assembly, extended part life, and reduced hourly production costs.

Our track links are forged from 35MNB special steel, reinforced with structural upgrades and advanced heat treatment for maximum strength and abrasion resistance. The self-lubricating system extends track chain bearing life, significantly reducing unplanned downtime.

Why Choose Our Track Links?

Specialized chain link furnace heat treatment process imparts excellent integrated mechanical characteristics
Supplementary high-frequency heat treatment strengthens chain link surfaces
Rigorous quality control maintained throughout entire manufacturing process
Stringent inspection regime and sophisticated testing equipment ensure product integrity
