X348 Heavy Duty Forged Scraper Chain for Conveyor & Trolley Chains

X348 Heavy-Duty Forged Scraper Chain - High-Performance Conveyor & Trolley Chains

Product Overview

The X348 Forged Scraper Chain series represents the pinnacle of heavy-duty material handling technology, engineered to withstand the most demanding mining, bulk handling, and industrial trolley applications. Manufactured through precision closed-die forging from premium alloy steels, these chains deliver 3-5× longer service life compared to conventional welded chains while maintaining 30% higher load capacity at equivalent weights.
