What the Link Rod Does in EX35 Excavators
The link rod on a mini excavator like the Hitachi EX35 connects the bucket cylinder to the bucket linkage, acting as a load-transferring member during bucket tilt, scoop, and dump operations. In compact machines, the stress per square inch on such parts can be intense due to faster cycle times and tighter articulation angles.
A high-quality link rod ensures smooth, accurate bucket movement and helps maintain the correct geometry between the boom, arm, and bucket. Worn or low-precision components often lead to pin deformation, excessive joint backlash, or uneven bucket wear—especially noticeable when trenching near edges or digging close to walls.
Material Strength and Structural Integrity
Our EX35 link rods are forged from Q345B or Q235B steel, selected based on the desired balance between strength and cost-efficiency. Q345B provides superior impact resistance, ideal for jobsites with rocky or hard soil conditions.
Once forged, the component undergoes CNC machining at the pin bores, bushing seats, and joint surfaces.To maximize longevity, the link rod is treated with shot blasting to clean the surface and prepare it for final coating. Depending on your requirement, it can be finished with either primer paint or electrophoretic coating (e-coating)—both offering strong resistance to rust, moisture, and corrosive site materials.
This added layer of protection is particularly beneficial for EX35 machines operating in wet, coastal, or chemical-prone environments, where untreated parts would corrode rapidly.
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.
Model Fitment
This link rod is compatible with Hitachi EX35 and its derivatives using standard linkage geometry:
EX35 / EX35U / EX35UR / EX35-2 / EX35-3
Not sure about compatibility? Just send us your machine's serial number, casting code, or drawing — we’ll verify the correct part within 12 hours.

Real-World Performance for Tight-Space Work
Hitachi EX35 is designed for residential work, urban trenching, and sidewalk excavation—scenarios that demand compact design but high functional strength. The link rod must not only endure high repetition but also maintain alignment under awkward bucket angles and confined movement paths.
This part’s high fatigue resistance, clean bore finish, and reinforced joint thickness ensure it can deliver long-term reliability in narrow, high-duty jobsites. It’s ideal for rental fleets, utility contractors, and operators seeking durability and reduced maintenance downtime.
Maintenance Tips to Extend Service Life
Even for compact machines, proper maintenance is key:
- Lubricate pin joints regularly to prevent metal-to-metal abrasion
- Inspect bore roundness and pin fit every 800–1,000 hours
- Replace pins and bushings together when installing a new link rod
- Avoid overloading or using the bucket as a pry bar to maintain rod integrity
