Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
Why the EX200 H-Link Matters
The H-link, also known as the center bracket or boom-arm connector, plays a crucial role in guiding the motion and maintaining the alignment between the boom and arm of your ZAX230 excavator. As one of the core mechanical joints in the front-end working group, it carries the brunt of dynamic force transfer during digging, swinging, and lifting operations.
For modern excavators like the ZAXIS 230, where responsiveness and breakout force are essential, the H-link must offer both high structural rigidity and precise geometry. If the H-link becomes worn or distorted, it can lead to misalignment of the linkage system, resulting in accelerated wear of bushings, pin deformation, and inefficient hydraulic motion—ultimately reducing machine performance and increasing long-term maintenance costs.
A reliable, OEM-standard H-link ensures your machine stays responsive, balanced, and protected in even the most demanding work cycles.
Material Engineering & Surface Protection
Each H-link for the ZAX230 is forged from Q345B or Q235B structural steel, offering superior strength, toughness, and weldability. Forging enhances internal grain flow and eliminates casting porosity, making the component highly resistant to fatigue and sudden impact.
After forging, the part undergoes CNC machining, focusing on the precision of bore diameters and flatness at mounting surfaces. To further improve resistance to harsh site conditions, the component is shot-blasted and treated with either a primer coating or electrophoretic (e-coat) process. This layer of protection helps prevent rust, especially when operating in humid, muddy, or chemically corrosive environments.
Before leaving the factory, every H-link passes through multi-step quality checks, including:
- Dimensional inspection using 3D coordinate measuring machines (CMM)
- Go/No-Go gauge testing at pin bores
- Ultrasonic flaw detection for internal defects
- Coating adhesion and thickness check to ensure lasting protection
Pre-Machining Storage
Before final processing, each H-link is carefully stored after forging and initial shaping. You can see the robust raw units neatly stacked and ready for CNC machining and heat treatment — a testament to our in-house forging capability and batch processing control.
Export-Ready Packaging
Once machining, inspection, and anti-rust treatment are complete, the finished H-links are securely packed in palletized crates or wooden boxes, ensuring safe transport over long distances. All packages are labeled for easy identification and can be customized with your logo or barcode if required.
Compatible Models & OEM Reference Numbers
This H-link is designed to fit Hitachi ZAXIS 230 series machines and other models with equivalent boom-arm geometry, including:
ZAX230 / ZAX230LC / ZAX230-3 / ZAX230-5G

Designed for Everyday Excavation Challenges
The ZAX230 excavator is often deployed in high-cycle operations across construction, infrastructure, pipeline excavation, and material loading. These applications demand more than just a standard linkage—they require an H-link that maintains alignment, strength, and reliability under repetitive stress.
This upgraded H-link is engineered to withstand long operating hours on uneven terrain, frequent shock loads, and rapid directional changes without distortion. It provides a strong, reliable pivot point that protects your pins, cylinders, and boom structure—especially during offset digging or swing-heavy cycles.
Maintenance Tips for Longevity
To maximize performance and extend service life, it’s essential to maintain the H-link regularly:
- Apply high-quality grease to both pin joints at set intervals
- Check for early signs of bore wear or cracking after every 1,000–1,200 hours
- Replace the H-link together with bushings or worn pins to prevent misalignment
- Avoid overextending boom-stroke angles under extreme loads
With proper care, your ZAX230 H-link can provide years of stable and safe operation.
