YuChai
Welcome to our Yuchai track link category, engineered to provide smooth power transmission, high structural rigidity, and exceptional wear life for Yuchai compact and medium excavators (including YC15, YC35, YC55, YC85, YC135, YC230, YC360). Shengan manufactures precision-forged 35MnB alloy steel track link groups, grease-sealed track chains, and heavy-duty track shoe assemblies. Whether you require mini excavator track chains, split-master link designs for rapid field maintenance, or heavy-duty track chains, our Yuchai track links ensure precise pitch alignment and severe-impact durability.

Premium Yuchai Track Link Assemblies & Sealed Track Chains by Shengan
In utility trenching, urban construction, forestry clearing, and heavy excavation, the structural integrity and seal reliability of your undercarriage track chain determine overall machine uptime and operating costs per hour. As an established heavy machinery undercarriage parts manufacturer, Shengan produces a full line of Yuchai track link assemblies engineered from forged high-strength alloy steel to endure continuous impact, severe torsional stress, and abrasive ground conditions.
Yuchai Track Link Category & Application Guide
To assist equipment dealers, fleet operators, and repair workshops in selecting the exact track chain configuration, we manufacture track link assemblies tailored for various machine weights, operating environments, and pitch standards:
| 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 (YC13, YC15, YC18, YC25, YC35) | Polyurethane seal rings, deep induction-hardened rail heads (HRC 52–58) |
| Medium Excavator Track Chains | High-tensile forged 35MnB boron steel | General earthmoving, road building (YC55, YC60, YC85, YC135, YC215) | Extended pitch accuracy, high pin retention force & smooth tracking motion |
| Heavy-Duty Mining Track Links | Forged alloy steel with deep hardened layer | Quarrying, heavy excavation, severe rock digging (YC230, YC360, YC450) | Extra-tall rail height, reinforced link strut geometry & 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 galling lead to sprocket tooth mismatch and accelerated roller wear. Every Shengan Yuchai track link group operates in perfect alignment with your track rollers, carrier rollers and custom sprocke through precise 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 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 grease leakage and internal pin-bushing wear during extended operating hours.
Custom Track Chain Engineering & OEM Manufacturing
For specialized applications, high-abrasion conditions, 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:
-
