Hitachi

Welcome to our Hitachi track link category, engineered to provide high-torque power transfer, track rail rigidity, and long wear life for Hitachi excavators (including EX120, EX200, ZX120, ZX200, ZX330, ZX470). Shengan manufactures precision-forged 35MnB alloy steel track link groups, grease-sealed track chains, and heavy-duty track shoe assemblies. Whether you need standard excavator track chains, split-master link designs for fast jobsite replacement, or heavy mining-grade chains, our Hitachi track links ensure optimal pitch alignment and severe-impact durability.

Premium Hitachi Track Link Assemblies & Sealed Track Chains by Shengan

In heavy excavation, mining, quarrying, and foundation engineering, the structural reliability and pin-bushing seal performance of your undercarriage track chain directly dictate machine uptime and cost per operating hour. As an established heavy machinery undercarriage parts manufacturer, Shengan produces a full line of Hitachi track link assemblies engineered from forged high-strength alloy steel to withstand extreme impact, severe bending loads, and abrasive soil conditions.

Hitachi Track Link Category & Application Guide

To assist equipment dealers, fleet managers, and repair workshops in selecting the exact track chain configuration, we manufacture track link assemblies tailored for various machinery tonnage, operating environments, and pitch standards:

OEM Compatibility: Hitachi, Caterpillar, Komatsu & Fleet Versatility

Minimizing maintenance downtime across multi-brand equipment fleets requires exact dimensional precision. Shengan track link assemblies are manufactured to strict OEM tolerances, seamlessly pairing with our full range of undercarriage parts across leading global brands:

Advanced Forging Metallurgy & Precision Heat Treatment

Pitch elongation and link rail surface galling lead to sprocket tooth mismatch and accelerated roller wear. Every Shengan Hitachi track link group operates smoothly with your  track rollers, carrier rollers and custom sprocket through advanced manufacturing controls:

• Forged 35MnB Boron Steel Construction: Closed-die precision forging aligns steel grain flow along link profiles, eliminating internal porosity and maximizing torsional fatigue strength.

• Differential Rail Head Induction Hardening: Track link rail surfaces undergo medium-frequency induction quenching (HRC 52–58, hardened depth 8mm–12mm) to prevent rail head surface chipping and uneven wear.

• Precision Pin & Bushing Bore Machining: Link bores are micro-machined on multi-station CNC centers to ensure exact pitch distance, preventing grease leakage and early joint play during extended operating hours.

Custom Track Chain Engineering & OEM Manufacturing

For specialized jobsite conditions, abrasive quarry environments, or custom crawler builds, Shengan offers end-to-end OEM/ODM track link manufacturing:

• Tailored Link Specifications: Custom link pitch lengths, modified bolt-hole patterns for specialized track shoes, and heavy-duty pin/bushing diameter options.

• Swamp & Specialty Configurations: Extended pitch chains for amphibious excavators, forest harvesters, and low-ground-pressure (LGP) crawler builds.

• FEA Structural Analysis & Prototyping: Every custom track link profile undergoes Finite Element Analysis (FEA) to verify stress distribution across link struts and pin bores prior to mass production.

Quality Assurance & Factory Direct Wholesale

Why global machinery dealers, contractors, and undercarriage distributors choose Shengan:

• 100% Magnetic & Ultrasonic Inspection: All forgings undergo Ultrasonic Testing (UT) and Magnetic Particle Inspection (MPI) to guarantee zero structural cracks or internal flaws.

• Factory-Direct Pricing: Direct manufacturing from our factory eliminates intermediary fees, delivering maximum cost savings to OEM and aftermarket buyers.

• Heavy-Duty Export Packaging: Export-grade steel-strapped wooden pallets, anti-corrosion protective coatings, and full shipping support to over 60 countries worldwide.
