As an important undercarriage component in crawler machinery, excavator track links play a critical role in maintaining stability, durability and working efficiency under complex operating conditions. High-quality track link production requires strict control from raw material selection to final assembly to ensure long service life and reliable performance for excavators, bulldozers and other tracked equipment.
Raw Material Selection
We adopt high-quality alloy steel as raw material, with stable chemical composition, high toughness and good wear resistance, which guarantees the basic performance of the track link.
Cutting & Forging
Raw steel bars are cut into fixed sizes by precision cutting machine. Then processed by hot forging under high temperature to make the track link blank. Forging makes the metal structure denser, effectively improving tensile strength and impact resistance.
Precision Machining
After forging and cooling, the blanks are processed by CNC machining: hole drilling, milling, finishing and dimensional calibration. All sizes are strictly controlled to ensure high precision and perfect assembly tolerance for excavator track links.
Heat Treatment
Adopt integral quenching and tempering + surface high-frequency quenching.
The track chain achieves high surface hardness for wear resistance, while keeping the inner core tough to avoid fracture under heavy impact.
Pin & Bushing Matching
Track pin and track bushing are made of professional alloy steel through fine turning and heat treatment. Strict matching clearance ensures flexible rotation, no stuck and long service life for heavy-duty excavator track links applications.
Assembly & Pre-tightening
Track links, pins and bushings are assembled by professional press equipment. After integral pre-tightening and pressure testing, the chain tension is uniform, not easy to loose or deform.
Surface Treatment & Finishing
Remove burrs, rust cleaning and anti-rust oil spraying. Strict quality inspection one by one before packaging, to ensure no defects and stable overall performance of each track link product.
With advanced production technology and strict quality control, modern excavator track links are widely used in mining, construction, quarry, roadwork and earthmoving equipment, providing reliable undercarriage support and extended service life in demanding working environments.
