Kobelco
Welcome to our Kobelco track link category, engineered to deliver high-torque power transmission, track rail rigidity, and long service life for Kobelco excavators (including SK60, SK120, SK200, SK210, SK330, SK350, SK480). Shengan manufactures precision-forged 35MnB alloy steel track link groups, grease-sealed track chains, and heavy-duty track shoe assemblies. Whether you require standard excavator track chains, split-master link designs for fast jobsite maintenance, or heavy mining-grade chains, our Kobelco track links guarantee precise pitch alignment and severe-impact resistance.

Premium Kobelco Track Link Assemblies & Sealed Track Chains by Shengan
In earthmoving, quarrying, demolition, and infrastructure trenching, the structural durability and pin-bushing seal performance of your undercarriage track chain directly influence equipment uptime and hourly operational costs. As a specialized heavy machinery undercarriage parts manufacturer, Shengan produces a comprehensive lineup of Kobelco track link assemblies engineered from forged high-strength alloy steel to withstand continuous high impact, severe torsional stress, and highly abrasive ground conditions.
Kobelco Track Link Category & Application Guide
To support equipment dealers, fleet managers, and repair workshops in selecting the precise track chain configuration, we manufacture track link assemblies tailored for various excavator operating weights, jobsite conditions, and pitch specifications:
| Track Link Category | Material & Heat Treatment | Application & Operating Environment | Key Structural Features |
| Mini & Compact Track Chains | Precision forged 35MnB / 40Mn2 alloy steel | Utility trenching, urban digging (SK30, SK35, SK50, SK60, SK75) | Polyurethane seal rings, deep induction-hardened rail heads (HRC 52–58) |
| Medium Excavator Track Chains | High-tensile forged 35MnB boron steel | Heavy earthmoving, road building (SK120, SK200-3/5/6/8, SK210LC, SK250) | Extended pitch accuracy, high pin retention force & smooth tracking motion |
| Heavy Mining Track Link Groups | Forged alloy steel with deep hardened layer | Quarrying, heavy mining, severe rock digging (SK330, SK350, SK480, SK850) | Extra-tall rail height, reinforced strut profile & anti-mushrooming rail heads |
| Split-Master Link Track Chains | Forged 35MnB alloy steel | Fast jobsite replacement & quick track shoe servicing | Interlocking diagonal master link design allowing installation without pin presses |

Advanced Forging Metallurgy & Precision Heat Treatment
Pitch elongation and link rail surface scoring cause premature sprocket tooth wear and accelerated roller misalignment. Every Shengan Kobelco track link group operates smoothly with your track rollers, carrier rollers and custom sprocket through precise process controls:
-
Forged 35MnB Boron Steel Construction: Closed-die precision forging aligns grain flow along link contours, eliminating internal porosity and providing superior torsional 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 cracking and uneven wear.
-
Precision Pin & Bushing Bore Machining: Link bores are micro-machined on multi-station CNC centers to ensure exact pitch distance, preventing seal failure and internal pin-bushing galling.
Custom Track Chain Engineering & OEM Manufacturing
For specialized applications, high-abrasion quarry environments, or custom crawler chassis builds, Shengan offers end-to-end OEM/ODM track link manufacturing:
-
Tailored Link Specifications: Custom link pitch dimensions, 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:
