隐藏域元素占位
Product Introduction
40Mn2 Forged Excavator Sprocket Rim (Drive Sprocket / Track Gear Segments) for E320
Fujian Yongsheng Machinery Parts Co., Ltd. (YSM) is an industry-leading source factory based in Quanzhou, China, specializing in heavy-duty crawler undercarriage components. Our E320 Excavator Sprocket series is precision-manufactured using high-grade 40Mn2 steel. What sets YSM apart from other aftermarket manufacturers is our advanced, comprehensive heat treatment process executed across the entire gear ring. This advanced treatment heavily enhances both ductility and structural strength, successfully minimizing gear deformation during high-stress field operations to ensure a safer, more efficient performance for Caterpillar CAT 320 series excavators.

Why International Wholesalers Choose YSM Forged Sprockets & Segments
- Flawless OEM Fitment: Tailored strictly to original Caterpillar engineering blueprints for the CAT 320 family. Tooth profiles, bolt hole pitches, and hub offsets are perfectly calibrated to guarantee seamless track engagement and an effortless swap-out.
- Advanced Full-Ring Induction Hardening: Cheap aftermarket sprockets only harden the tooth tips, causing early gear snapping under load. YSM hardens the entire gear ring structure. This advanced depth pattern optimizes internal ductility, allowing the sprocket to absorb relentless drive stress without breaking.
- Massive Structural Capacity: Our extensive manufacturing capability covers both monolithic whole sprockets for compact-to-mining machines (0.8-125T) and high-strength replacement segment blocks for heavy tracked tractors (6-100T), answering all fleet demands.
- Trusted Global Quality Background: Backed by years of contract manufacturing experience executing undercarriage components that satisfy the strict quality thresholds of premium global aftermarket brands like ITR, YSM brings top-tier China factory reliability directly to international distributors.
