Hot sale HITACHI EX120 135-2-3-5 MAIN BOOM BASE PIN BUSHING 71 X 86 X 75MM HEIGHT | Tonkee®

The main boom base pin bushing is typically made from high-quality materials to withstand the immense forces and wear and tear experienced during the operation of the Hitachi EX120-135-2-3-5 excavator.

These materials are often hardened steel or other robust alloys. The choice of material is crucial to ensure longevity and resistance to deformation.

Dimensional Specifications:

The bushing measures 71 x 86 x 75mm (height). These precise measurements are critical for a proper fit within the boom assembly, ensuring that there is minimal play or movement between parts. A secure fit is essential to maintain the structural integrity of the boom and prevent premature wear.

Function:

The main boom base pin bushing serves as a crucial component in the pivot point of the boom assembly. It provides a low-friction surface for the main boom pin to rotate on. This reduces the wear and tear on both the pin and the boom, extending the operational life of the excavator.

Load-Bearing Capacity:

The bushing is subjected to significant loads during excavator operation, including the weight of the boom, the force exerted by attachments, and the resistance encountered during digging. Therefore, it must have a high load-bearing capacity to withstand these forces without deformation or failure.

Lubrication:

Proper lubrication is essential to reduce friction and heat generated during the rotation of the main boom pin within the bushing.

Regular maintenance, including greasing, is required to ensure smooth operation and prevent premature wear. The choice of lubricant should be in accordance with the manufacturer's recommendations.

Replacement and Maintenance:

Over time, the main boom base pin bushing may wear out due to the harsh operating conditions it endures. Regular inspection is essential to identify signs of wear or damage. When replacement is necessary, it's crucial to use a genuine Hitachi part to ensure compatibility and maintain the excavator's performance and safety.

Compatibility:

The bushing is designed specifically for use in the Hitachi EX120-135-2-3-5 excavator models. It is engineered to meet the exacting standards and specifications set by Hitachi to guarantee optimal performance and safety.

Safety Considerations:

The proper functioning of the main boom base pin bushing is integral to the safe operation of the excavator. Any failure or excessive wear in this component can lead to instability and accidents. Regular inspections and maintenance of this component are paramount to ensure safe and efficient excavation operations.
