隐藏域元素占位
Product Introduction
35MnB Forged Excavator Track Link Assembly (Crawler Track Chain / Link Rails) for E320
Fujian Yongsheng Machinery Parts Co., Ltd. (YSM) is an established source factory based in Quanzhou, China, specializing in heavy-duty crawler undercarriage components. Our E320 Track Link series is manufactured using premium-grade 35MnB alloy steel sourced directly from industry giants like Hangzhou Steel and Baosteel. Engineered specifically to meet the high-wear demands of rugged mining, quarrying, and construction sites, our track chains provide maximum structural integrity and structural durability for Caterpillar CAT 320 series excavators.

Why YSM 35MnB Forged Track Chains Outperform the Market
- Elite 35MnB Steel vs. Standard 40Mn2: While standard aftermarket track links use lower-grade 40Mn2 or 40MnB steel which prematurely stretches or cracks under severe impact, YSM adopts heavy-duty 35MnB steel. This choice ensures superior metal density and higher wear resistance during high-stress operations.
- Deep Induction Hardening (5-8mm): Through localized induction heat treatment, our link rail surfaces maintain a stable HRC 47-55 hardness extending deep into the wear rail. This deep case hardening prevents link deformation and rail scalloping.
- Premium South Korean Oil Seals: For crawler systems requiring continuous mobile operations, we provide heavy-duty lubricated track chains. Equipped with high-precision oil seals imported from South Korea, our assemblies entirely eliminate pin-and-bushing oil leakage.
- Trusted OEM Background: Backed by years of contract manufacturing experience executing undercarriage components that seamlessly fit the strict quality thresholds of premium global brands like ITR, YSM brings factory-direct reliability and wholesale pricing directly from China.
