Product Parameters

The excavator idler wheel, also known as the guide wheel or tensioning wheel, is a critical component of the excavator’s undercarriage system. Positioned at the front of the track frame, it works in tandem with the track chain, sprocket, and carrier rollers to guide the track’s movement and maintain proper tension. Its performance directly impacts the excavator’s stability, maneuverability, and overall operational efficiency.

Structural Components

1. Wheel Body: Typically forged or cast from high-strength steel, the wheel body is designed for exceptional wear and impact resistance. Surface treatments such as quenching or carburizing enhance its hardness and durability.

2. Bearings: High-precision rolling bearings are installed inside the wheel body to support smooth rotation under heavy loads.

3. Seals: Advanced sealing systems prevent contaminants (e.g., dirt, moisture) from entering the bearing assembly, ensuring long-term lubrication and functionality.

4. Mounting Hardware: Bolts and brackets securely attach the idler wheel to the track frame, with torque specifications strictly followed to guarantee structural integrity.

Excavators are widely used in the following fields:

Construction engineering: used for earthwork excavation, foundation treatment, etc.

Mining: The extraction of resources such as ore and coal.

Road construction: roadbed excavation, pipeline laying, etc.

Water conservancy engineering: river dredging, dam construction, etc.

Municipal engineering: pipeline laying, greening construction, etc.

Agriculture: land leveling, ditch excavation, etc.

Emergency rescue: clearing ruins, clearing roads, etc.

Maintenance and upkeep

Regular inspection: Check the wear of the guide wheel rim and replace severely worn components in a timely manner.

Lubrication and maintenance: Regularly add lubricating grease to the bearings to ensure smooth rotation of the wheel body.

Cleaning: Timely clean the dirt, gravel and other debris on the guide wheel to prevent them from entering the bearing and causing damage.

Check the tension: Regularly check the tension of the track to ensure it is in the appropriate state and avoid being too loose or too tight.
