Manufactured through advanced technical design and subjected to deep case hardening, the track link delivers maximum strength and wear resistance.
All pin bushings are cold extruded from raw materials to ensure uniform distribution of steel fibers, followed by carburizing to achieve optimal core hardness and superior surface wear resistance.
Each pin undergoes specialized heat treatment and deep hardening to ensure excellent wear resistance. It is impact-resistant, stress-resistant, and most importantly, retains consistent robust properties.
The simple design makes the main link easy to clean, assemble and disassemble, while ensuring reliability and durability.
