OEM HITACHI EX30 SERIES KINGPOST MAIN PIN BUSHING 80 X 95 X 50MM HEIGHT | Tonkee®

The Hitachi EX30 Series Kingpost Main Pin Bushing is typically made from high-quality materials such as bronze or steel.

These materials are chosen for their exceptional durability, resistance to wear, and ability to withstand the heavy loads and constant movement that construction equipment experiences. This durability is essential to ensure the longevity of the bushing and reduce maintenance and replacement costs.

Dimensions:
The bushing has precise dimensions of 80mm (inside diameter), 95mm (outside diameter), and a height of 50mm. These dimensions are standardized to fit perfectly within the kingpost assembly of the Hitachi EX30 Series excavators, ensuring a secure and reliable fit.

Function:
The primary function of the kingpost main pin bushing is to provide a low-friction, wear-resistant interface between the kingpost pin and the surrounding components. The kingpost pin is a critical pivot point in the excavator's boom and arm assembly, allowing for the articulation and movement necessary for various construction tasks.

Reduced Friction:
The bushing's inner surface is precisely machined to minimize friction between the kingpost pin and the bushing itself.

This reduction in friction is essential for smooth and efficient movement, which not only improves the machine's performance but also reduces energy consumption and extends the lifespan of the components.

Wear Resistance:
Construction equipment operates in demanding environments, often involving abrasive materials and heavy loads. The Hitachi EX30 Series Kingpost Main Pin Bushing's material and design provide excellent wear resistance, ensuring that it can withstand the rigors of daily use without deteriorating quickly.

Easy Replacement:
Over time, even the most durable bushings will wear out due to the harsh conditions they operate in. Fortunately, replacing the bushing is a relatively straightforward maintenance task for experienced technicians. This allows for minimal downtime, ensuring that the excavator can quickly return to full operational capacity.

Compatibility:
The bushing is specifically designed to fit the Hitachi EX30 Series excavators, making it a genuine replacement part. This ensures that it meets the manufacturer's quality and performance standards, providing peace of mind to equipment owners and operators.
