Purpose of the Link Rod in SK200
The link rod, also known as the bucket linkage arm, is the central component connecting the bucket cylinder to the bucket mechanism in the SK200 excavator. During digging, trenching, or loading operations, it transmits force while maintaining stable movement and alignment between the arm and bucket.
In high-cycle environments such as earthmoving, quarrying, or road foundation work, the SK200 operates under intense loads. The link rod must provide not only strength but also pin-hole accuracy, ensuring that hydraulic forces are transferred smoothly without introducing vibration, misalignment, or premature bushing wear.
Material Strength and Structural Integrity
We use Q345B or Q235B structural steel to manufacture the SK200 link rod, depending on required tensile strength and durability. Q345B, with higher yield strength, is ideal for heavy-duty applications such as rocky terrain, deep trenching, or harsh impact zones.
The forging process enhances the internal structure of the steel, eliminating weak points that may arise from casting. As a result, the link rod delivers superior impact resistance, crack prevention, and long-term dimensional stability—a must for contractors working across tough environments.
After forging, the link rod is CNC-machined at critical areas, especially the pin bores and contact surfaces, to ensure accurate fitment with OEM cylinders and bucket joints.
To resist rust, chemical exposure, and environmental wear, the link rod receives shot-blasting followed by a protective surface finish. We offer both primer-based painting and electrophoretic coating (e-coating) based on customer request—both ensuring extended corrosion resistance.
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.
Fitment Range
This link rod is compatible with a wide range of Kobelco SK200 excavators, including:
- SK200 / SK200-3 / SK200-5 / SK200-6 / SK200-8 / SK200-10
- SK200LC / SK200LC-3 / SK200LC-8 / SK200-10LC
- SK210 / SK210LC / SK210HD (depending on linkage configuration)

Built for Mid-Size Excavator Demands
The Kobelco SK200 is a 20-ton class excavator widely used in infrastructure, demolition, and quarry applications. These scenarios demand consistent bucket control and reliable linkage behavior even under sudden impact loads or sloped digging angles.
Our link rod for SK200 maintains long-term joint integrity, reduces bushing fatigue, and ensures smooth bucket travel across thousands of working cycles. Whether in wet soils, clay pits, or demolition zones, this component performs with minimal deviation or downtime.
Maintenance Tips for SK200 Link Rods
- Grease all pin joints every 250–500 working hours
- Check bore roundness and pin clearance every 1,000 hours
- Always replace pins and bushings when installing a new link rod
- Avoid overloading or swinging with side stress to reduce fatigue on the linkage arm
Proper maintenance helps extend part life and reduces the wear rate of hydraulic components.
