China HITACHI EX60-5 ZAXIS ZX SERIES TRACK IDLER WHEEL | Tonkee®

The track idler wheel is an integral part of an excavator's undercarriage system.

Its primary function is to support the weight of the excavator and the tension in the track chain. It helps maintain proper track tension, reduce track wear, and improve overall stability and traction during operation.

Material and Construction:
The Hitachi EX60-5 ZAXIS ZX Series Track Idler Wheel is typically constructed from high-strength, wear-resistant materials such as steel or alloy steel. It undergoes precision machining to ensure dimensional accuracy and durability. The surface may also be treated with coatings or heat treatment to enhance wear resistance.

Design and Dimensions:
The specific design and dimensions of the idler wheel can vary depending on the model and manufacturer. However, for the Hitachi EX60-5 ZAXIS ZX Series, the idler wheel is typically designed to match the machine's weight, track width, and track link pitch for optimal performance. It has a cylindrical shape with flanges on both sides to guide the track chain.

Bearings and Lubrication:
The idler wheel incorporates high-quality, sealed bearings to ensure smooth rotation and reduce friction. Proper lubrication is crucial to extend the life of these bearings and maintain the idler's functionality. Lubrication may be achieved through grease fittings or oil bath systems, depending on the design.

Mounting and Installation:
Installing the idler wheel correctly is essential for the excavator's performance and longevity.

It is typically mounted to the idler frame, which is part of the undercarriage assembly. The idler wheel's precise alignment is crucial to ensure proper track tension and prevent premature wear on the track components.

Maintenance and Inspection:
Regular maintenance and inspection of the idler wheel are necessary to identify wear, damage, or alignment issues. Inspections should include checking for loose bolts, lubrication levels, and signs of wear on the wheel's surface. Timely maintenance can prevent costly repairs and downtime.

Compatibility:
The Hitachi EX60-5 ZAXIS ZX Series Track Idler Wheel is designed specifically for this series of excavators. It is essential to ensure that replacement idler wheels are compatible with the machine's specifications to maintain performance and safety.
