Why the EX200 H-Link Matters
The link rod, often referred to as a bucket link or bucket connecting rod, is a key mechanical part that transfers force between the bucket cylinder and bucket linkage group. On the Hitachi EX200, it plays a vital role in maintaining the proper motion geometry and ensures efficient digging, lifting, and bucket rotation.
As the bucket moves through its range of motion, the link rod absorbs both compressive and tensile loads. When this part wears, bends, or cracks, it can cause hydraulic loss, unbalanced force transfer, and accelerated wear on pins and bushings. That’s why using a high-precision, high-strength link rod is critical to keeping the excavator’s front-end working group aligned and efficient.
Material Strength and Structural Integrity
Our EX200 link rods are built from Q345B or Q235B structural steel, both known for excellent mechanical strength and weldability. Q345B offers superior yield strength, making it ideal for high-impact excavation tasks, while Q235B provides cost-effective durability for lighter operations.
The forging process eliminates internal porosity and creates a dense grain structure, allowing the rod to withstand repeated bending forces and side loading without deformation. This is particularly important for EX200 machines operating in rocky or uneven soil, where high side torque is common during trenching or prying.
All pin bores and connecting faces are machined to OEM-standard tolerances, ensuring smooth articulation with the bucket and cylinder. Once machining is complete, the part is shot-blasted and finished with either primer paint or electrophoretic (e-coat) surface treatment to protect against rust, abrasion, and chemical exposure.
Pre-Machining Storage
After forging and rough shaping, each link rod is properly stored in preparation for precision machining and heat treatment. These solid, semi-finished parts are neatly arranged in batches — showcasing both our forging strength and our ability to manage stable, large-scale production.
Export-Ready Packaging
After completing all machining, quality checks, and anti-corrosion treatment, each finished link rod is carefully packed using reinforced pallets or wooden crates. This ensures safe handling and long-distance transport. Every package is clearly labeled for easy tracking, and logo or barcode customization is available upon request.

Performance Under Real-World Conditions
The EX200 is often deployed for infrastructure construction, river channel work, road excavation, and more. These work environments involve frequent changes in direction, sudden shock loading, and unbalanced lifting angles. A subpar link rod can fail under these real-world stresses.
Our reinforced link rod ensures long-term reliability across a wide range of operating conditions. Whether you're trenching through clay, loading aggregates, or lifting debris, this component preserves machine balance and bucket control.
Maintenance Tips to Extend Service Life
To keep your link rod performing at its best:
- Grease both ends regularly, especially in dusty or wet conditions
- Replace worn pins and bushings at the same time as the rod to prevent uneven loading
- Inspect for cracks, bore elongation, or surface fatigue every 1,000–1,200 hours
- Avoid prying operations beyond rated bucket force
Following these best practices helps prevent early wear and keeps your excavator performing reliably on-site.
