Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The Hitachi EX1200 is a true mining-class excavator, working under extreme loading forces, abrasive ground materials, and nonstop operational cycles. For such a machine, the track link assembly becomes one of the most critical undercarriage components, directly affecting ground traction, machine stability, and overall productivity.
This EX1200 track link assembly is engineered specifically for large excavators that run long hours in harsh environments such as open-pit mines, iron ore sites, rock quarries, and large-scale earthmoving projects. Compared with standard construction-class undercarriage chains, this model emphasizes maximum structural density, wear resistance, and impact absorption, ensuring dependable performance under heavy shock loads.
Massive, High-Tensile Alloy Steel Structure
A machine of the EX1200’s size demands a track chain capable of supporting extreme operating weight, bucket breakout force, and continuous vibration. To meet these demands, each link is forged from high-tensile alloy steel, selected for:
- exceptional resistance to cracking
- stable mechanical strength under massive compression
- superior toughness in low-lubrication or abrasive conditions
The forging process eliminates internal voids and improves grain uniformity, producing a chain that can resist deformation even when working under repeated full-cycle loading.
Deep Induction-Hardened Bushings and Pins for Long Wear Life
The EX1200 track link assembly utilizes bushings and pins that undergo a deep induction hardening process. This treatment enhances resistance against two of the most damaging mining factors: metal-to-metal friction and abrasive penetration from fine minerals.
The hardened layer ensures:
- significantly extended link pitch life
- stronger resistance to internal wear during rotation
- reduced risk of bushing cracking or flattening
- smoother chain travel over idlers and sprockets
Because mining excavators often run continuously, bushing life is a crucial element that directly impacts operating cost per hour.
Track Link Forging & Machining
The raw track links are forged into form, then machined to ensure uniform pitch and hole alignment. Precision is essential for proper sprocket and bushing engagement.
Pin and Bushing
Hardened pins are inserted between the links to create a flexible, load-bearing chain. The sealing system prevents grease leakage and contaminant ingress.
Painting & Surface Coating
After assembly, the entire chain is cleaned and painted with industrial-grade coatings to protect against rust, humidity, and chemical corrosion on job sites.
Final Inspection & Packaging
Before shipping, the chains undergo dimensional checks and torque verification. Chains are then packed securely on wooden pallets or steel frames to avoid deformation.
Reinforced Link Profile for Heavy Impact and Rock Abrasion
Unlike mid-size excavators, the EX1200 constantly faces high-energy contact with fractured rock and compacted ore deposits. The track link shape is engineered to withstand:
- side-loading caused by uneven rock surfaces
- high impact when the machine turns under load
- abrasive wear from sharp stones and mineral particles
A reinforced outer profile maintains dimensional accuracy, supporting a smooth interface with rollers and sprockets, even after thousands of operating hours in aggressive terrain.
Stable Ground Traction and Smooth Travel on Harsh Terrain
A stable, accurate track chain is essential for maintaining the EX1200’s digging balance and machine positioning. This chain’s structural rigidity ensures that each link retains its pitch, helping the machine achieve:
- stable traction even on loose or crushed rock
- minimized vibration transmitted to the upper frame
- improved digging precision in deep mining benches
- smoother travel when moving fully loaded or uphill
These performance factors directly contribute to operator comfort and reduced mechanical stress throughout the entire undercarriage system.
Designed for Long Operating Cycles in Mining Operations
EX1200 excavators typically operate in shift cycles that allow little downtime. This track link assembly is built with that in mind. Its metallurgy, heat treatment, and bushing hardness are optimized for:
- continuous 24/7 mining applications
- long intervals between maintenance
- reduced lubrication requirements
- predictable wear pattern and easy servicing
The result is an undercarriage chain that reduces unplanned shutdowns and extends component lifespan, helping mines control operational costs.
Precision-Matched Pitch and OEM-Standard Fitment
The chain is manufactured according to Hitachi’s OEM pitch specifications to ensure perfect compatibility with EX1200 undercarriage components, including:
- track rollers
- carrier rollers
- idlers
- sprockets
Accurate pitch control reduces scalloping, ensures stable tracking, and minimizes the risk of derailment—critical for a machine operating on unstable or sloped terrain.

Surface Protection Against Corrosion and Mineral Penetration
Mining environments expose undercarriage parts to moisture, chemicals, salt, and fine mineral dust. The chain receives a protective treatment that improves resistance against:
- corrosion in wet ore
- oxidation during long idle periods
- abrasive chemical compounds found in mineral deposits
This allows the chain to maintain structural integrity and smooth articulation longer, even in highly corrosive environments.
Maintenance Recommendations for Maximum Service Life
Even with heavy-duty construction, a mining-class chain requires proper upkeep to achieve full lifespan. Recommended practices include:
- regular inspection of link pitch and bushing wear
- maintaining correct track tension to prevent shock loading
- cleaning fine minerals that accumulate between links
- monitoring travel motor load during operation
- replacing worn pins and bushings before secondary damage occurs
A well-maintained undercarriage directly enhances operating performance and reduces long-term maintenance costs.
