Buy HITACHI EX100 120-1 SERIES TRACK IDLER WHEEL | Tonkee®

The Hitachi EX100-1 and EX120-1 series track idler wheel is meticulously designed and constructed to withstand the harsh operating conditions commonly encountered in construction and excavation projects.

It is crafted from high-quality materials, typically featuring a combination of heavy-duty steel and durable, wear-resistant components.

Function:
The primary function of the track idler wheel is to guide and support the track chain as it moves along the excavator's undercarriage. This component maintains proper tension in the track chain, preventing slack that can lead to misalignment or derailment. It also helps distribute the machine's weight evenly across the tracks, minimizing ground pressure and ensuring stability on various terrains.

Size and Dimensions:
The dimensions of the Hitachi EX100-1 and EX120-1 series track idler wheel can vary depending on the specific model and manufacturer specifications. However, a typical idler wheel for these excavators has a diameter ranging from 400 to 500 millimeters (16 to 20 inches) and a width of 200 to 250 millimeters (8 to 10 inches). These dimensions are carefully engineered to provide optimal support and tracking performance.

Mounting and Installation:
The track idler wheel is mounted on the excavator's undercarriage using a robust mounting bracket and fasteners. Installation requires precise alignment to ensure proper tracking and tension of the track chain. It is essential to follow manufacturer guidelines and use appropriate tools for installation to ensure the idler wheel functions effectively and safely.

Bearings and Seals:
To ensure smooth rotation and longevity, the track idler wheel is equipped with high-quality bearings and seals.

These components reduce friction and protect the internal mechanisms from contamination, such as dirt, debris, and water, which can cause premature wear and damage.

Adjustability:
Many track idler wheels are designed with adjustability features. These allow operators or maintenance personnel to fine-tune the tension in the track chain to match the operating conditions and terrain. Proper tensioning is critical for maximizing the lifespan of both the idler wheel and the track chain.

Maintenance and Inspection:
Regular maintenance and inspection of the track idler wheel are essential to ensure its continued performance and prevent costly downtime. This includes lubrication of bearings, checking for signs of wear or damage, and monitoring the tension in the track chain. Timely replacement of worn or damaged idler wheels is crucial to prevent further damage to the undercarriage system.

Compatibility:
The Hitachi EX100-1 and EX120-1 series track idler wheel is designed specifically for these excavator models. However, compatibility may vary based on the manufacturer and aftermarket options. It is essential to verify compatibility with the excavator model and consult manufacturer guidelines when selecting replacement idler wheels.
