The Hitachi ZAX55 idler plays a crucial role in the movement and stability of your excavator. Positioned at the front of the undercarriage, it guides the track forward and backward and assists in absorbing shock and reducing wear. It ensures proper track tension, prevents track derailment, and provides stability for your excavator when traversing rough, clay-rich, gravel, or hard clay terrains. Without a durable idler, your undercarriage components would suffer faster wear and your operations would become less efficient.

Description
Material, Manufacturing Process & Structural Advantages
The ZAX55 idler wheel is manufactured from high-strength alloy steel, which provides outstanding toughness and resistance to wear and deformation.
During production, we use precision forging and CNC machining techniques to form and shape the components accurately. The idler undergoes induction hardening to HRC 52-58, adding a hard, wear-resistant surface while retaining a tough, shock-absorbing core.
Furthermore, specialized bushings and seals are carefully manufactured and fitted to minimize friction and prolong service life. The result is a durable idler that performs smoothly under heavy loading and challenging conditions.
Below are some real pictures of our factory, showing our real production process.
