Product Introduction
35MnB Forged Excavator Track Link Assembly (Crawler Track Chain / Link Rails) for E300
Fujian Yongsheng Machinery Parts Co., Ltd. (YSM) is an established source factory in Quanzhou, China, specializing in world-class heavy machinery undercarriage components. Our E300 Track Link series is precision-crafted using high-tier 35MnB alloy steel supplied by industry giants like Baosteel and Hangzhou Steel. Tailored to survive the grueling environmental demands of global mining, quarrying, and high-impact construction, our track chains deliver maximum structural integrity and structural durability for Caterpillar CAT E300 series excavators.

Why Global Wholesalers Prefer YSM 35MnB Forged Track Chains
- Elite 35MnB Structural Strength: While ordinary aftermarket links use 40Mn2 steel which often suffers from link stretching or body cracking under heavy quarry impacts, YSM adopts mining-grade 35MnB steel. This forces a higher core density to endure continuous operational stress.
- Deep Case Hardening (5-8mm): Utilizing advanced localized heat treatment tech, our link rail surfaces maintain an intense HRC 47-55 hardness depth. This robust hardening pattern prevents early link deformation and rail scalloping in harsh terrains.
- Imported South Korean Oil Seals: For heavy crawler excavators requiring constant mobile field operations, we provide sealed lubricated track chains. Equipped with high-precision oil seals imported from South Korea, our assemblies eliminate pin-and-bushing oil loss.
- Trusted OEM Background Contract: Backed by years of manufacturing expertise supplying undercarriage parts that satisfy the rigid quality thresholds of top global brands like ITR, YSM brings top-tier China factory reliability directly to international distributors.
