Heavy-Duty Precision Heat-Treated Track Chain for Komatsu PC300 - Track Link & Shoe Assembly
Engineered to eliminate premature track link wear, frequent replacements, and costly downtime, our components deliver reliable performance in the toughest mining and construction environments.
Heavy Track Link Features: Precision-Engineered for Uninterrupted Performance
We leverage advanced machining centers paired with horizontal and vertical CNC equipment to execute critical processes—high-precision turning, drilling, threading, and milling—on every part. This strict manufacturing standard guarantees superior component quality, seamless assembly accuracy, extended service life, and minimized hourly production costs.
Our track links are forged from high-grade 35MNB special steel, then enhanced with structural reinforcement technology and advanced heat treatment processes. The result is unbeatable maximum strength and exceptional abrasion resistance that stands up to heavy loads and abrasive terrain. The integrated self-lubricating system drastically reduces friction and wear, significantly extending the service life of track chain bearings and slashing unplanned maintenance stops.
