The Hitachi dipper arm bushing has a specific size of 65 x 80 x 50mm (inner diameter x outer diameter x height).

These dimensions are critical to ensure proper fitment and functionality within the excavator's dipper arm assembly.

Material Composition:
This bushing is typically constructed from high-quality materials such as bronze or steel. These materials are chosen for their durability, corrosion resistance, and ability to withstand heavy loads and abrasive conditions commonly encountered in construction and excavation environments.

Function:
The primary function of the dipper arm bushing is to act as a pivotal connection point between the dipper arm and the bucket or attachment of the excavator. It allows for the smooth rotation and movement of the dipper arm, enabling precise digging, lifting, and dumping of materials.

Compatibility:
The Hitachi EX120-5, 135 ZAXIS ZX130-1-3 Series Dipper Arm Bushing is designed specifically for use with Hitachi excavators within the EX120-5, 135 ZAXIS, ZX130-1, ZX130-2, and ZX130-3 series.

It is essential to ensure that the bushing matches the exact specifications and requirements of the particular excavator model to maintain optimal performance and safety.

Wear Resistance:
Due to the constant movement and friction experienced during excavator operations, the bushing is subjected to wear and tear. The Hitachi bushing is engineered to withstand high levels of wear and has a long service life, reducing downtime and maintenance costs.

Lubrication:
Proper lubrication is crucial for extending the life of the bushing and ensuring smooth operation. Regular maintenance and lubrication of the bushing help reduce friction, heat buildup, and premature wear.
