Caterpillar

Welcome to our Caterpillar track link category, engineered to provide high-torque power transfer, track rail rigidity, and long wear life for Cat excavators and dozers (including Cat 320, 330, 336, 349, D3K, D5K, D6N, D8T). Shengan manufactures precision-forged 35MnB alloy steel track link groups, sealed and lubricated track chains (SALT), and heavy-duty track shoe assemblies. Whether you need standard excavator track chains, split-master link designs for fast field maintenance, or custom-pitch undercarriage chains, our track links ensure optimal pitch alignment and severe-impact durability.

Premium Caterpillar Track Link Assemblies & Sealed Track Chains by Shengan

In heavy earthmoving, trenching, rock quarrying, and land clearing, the structural integrity and surface hardness of your undercarriage track chain determine machine uptime, fuel efficiency, and operating costs per hour. As a specialized heavy machinery undercarriage parts manufacturer, Shengan produces a complete range of Caterpillar track link assemblies engineered from forged high-strength alloy steel to endure continuous impact, severe bending loads, and abrasive soil conditions.

Caterpillar Track Link Category & Application Guide

To assist equipment dealers, fleet managers, and field technicians in selecting the optimal track chain configuration, we manufacture track link assemblies tailored for diverse machinery weights, operating environments, and pitch standards:

Track Link Category Material & Heat Treatment Application & Operating Environment Key Structural Features
Excavator Grease Sealed Track Chains Precision forged 35MnB / 40Mn2 alloy steel Medium to heavy excavation (Cat 312, 320, 325, 330, 336, 349) Polyurethane Duo-Cone seals, deep induction-hardened rail heads (HRC 52–58) to prevent pin wear
Dozer Sealed & Lubricated Track Chains (SALT) High-tensile forged alloy steel with oil reservoirs Heavy earthmoving, land clearing, push-dozing (Cat D3K, D5K, D6N, D7G, D8T) Internal oil reservoir pin lubrication, synthetic seal rings & high pin-to-bushing retention force
Heavy Mining Track Link Groups Forged boron steel with deep hardened layer Quarrying, mining, severe rock digging (Cat 374, 390, D9T, D10T) Extra-tall rail height, reinforced strut geometry & extreme resistance to rail head mushrooming
Split-Master Link Track Chains Forged 35MnB alloy steel Fast jobsite replacement & quick track assembly servicing Interlocking split-diagonal tooth design allowing easy track removal without hydraulic presses

OEM Compatibility: Caterpillar, Komatsu, Hitachi & Fleet Versatility

Reducing maintenance downtime across multi-brand machinery 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:

Komatsu PC130, PC200, PC300, PC400 / D65, D85 Compatible with our Komatsu track link groups and track rollers
Hitachi EX120, EX200, ZX120, ZX200, ZX330, ZX470 Fully interchangeable with Hitachi track link and carrier rollers

Advanced Forging Metallurgy & Precision Heat Treatment

Excessive pitch elongation and link rail wear lead to sprocket misalignment and rapid undercarriage wear. Every Shengan Caterpillar track link group operates in perfect harmony with your track rollers, carrier rollers and custom sprocket through advanced manufacturing controls:

  • Forged 35MnB Boron Steel Construction: Closed-die forging ensures optimal grain flow alignment along the link body, eliminating internal voids and offering superior fatigue resistance under heavy torsional loads.

  • 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 lines to ensure exact pitch distance, preventing pitch elongation and seal leakage during extended operating hours.

Custom Track Chain Engineering & OEM Manufacturing

For specialized jobsite requirements, high-abrasion soil conditions, or custom machinery 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 custom 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.
