Detailed Description

The 0420112 BUSHING HITACHI is designed to extend the operational life of critical moving joints in construction and mining equipment. As machinery undergoes continuous cycles of stress, impact, and vibration, it’s the bushing that absorbs this pressure—preserving the integrity of structural components like arms, booms, and linkage systems.

Constructed from a wear-resistant alloy and treated for superior surface hardness, the 0420112 bushing effectively resists pitting, galling, and abrasive wear. Its inner surface is precision-honed to ensure tight tolerance alignment with pivot pins, facilitating smooth movement with reduced metal-on-metal contact.

The design also incorporates a high-lubricity finish, which helps retain grease and reduce maintenance intervals. This feature ensures that your equipment operates with optimal efficiency even in extreme environmental conditions such as mud, gravel, heat, and hydraulic exposure.

Whether used in upper or lower frame articulation points, this bushing provides consistent, reliable operation. It’s easy to install and aligns perfectly with original component geometries, ensuring hassle-free replacement and minimal downtime.

Role in Excavation Systems

Bushings like the 0420112 BUSHING HITACHI are fundamental to maintaining smooth and precise operation in articulating joints. These parts serve as sacrificial layers between high-friction components, absorbing stress and preventing damage to more expensive structural parts.

In practical terms, this bushing:

• Absorbs shock during excavation and material handling

• Reduces noise and vibration in pivot assemblies

• Maintains alignment between pins and bores

• Prevents elongation of housing and bracket holes

• Enables smooth bucket and boom motion, even under high loads

By doing so, the bushing not only preserves the machine’s mechanical integrity but also enhances safety and efficiency during operation.

Maintenance and Replacement

As with any mechanical wear component, regular inspection of the 0420112 BUSHING HITACHI is crucial. Signs that it may need replacement include:

• Excessive play or looseness in joints

• Visible scoring or pitting

• Squeaking or grinding noises during articulation

• Misalignment in bucket or boom movement

• Pin wear or deformation

Timely replacement of worn bushings prevents damage to adjoining components and reduces long-term repair costs. The 0420112 bushing is designed for fast, straightforward installation, making it ideal for scheduled maintenance programs.
