Product Overview
Our heavy-duty roller chains (heavy-series chains) feature thicker side plates than standard ones, greatly enhancing shock load capacity and tensile strength. Manufactured in line with ANSI, ISO and DIN standards, they boast precision components and advanced processes for superior durability, wear resistance and long service life. We provide simplex/duplex/triplex configurations, riveted or cottered designs to match your equipment needs.
Core Features & Advantages
Exceptional Strength & Durability: Made of high-quality carbon steel or alloy steel (40Mn, 42CrMo), all components undergo strict heat treatment (through hardening, carburizing, nitro-carburizing) and shot peening. Thicker side plates, solid bushings and rollers further improve load-bearing capacity and service life for harsh industrial use.
Precision Manufacturing: Produced with advanced CNC equipment and strict quality control, our chains have precise dimensions and tight tolerances, ensuring smooth operation, low noise and reduced friction. Pre-stretched and pre-lubricated to eliminate initial elongation.
Wide Application Range: Suitable for construction, mining, agriculture, material handling and other heavy industries, even replace "super" series, HE, K or HK chains from other brands.
Customization Service: Full customization available—size, pitch, strand number, material (including stainless steel), surface treatment, or special designs based on your drawings/samples, tailored by our professional engineering team.
Mass Production Capacity: Advanced automated production lines and large-scale base enable efficient bulk order fulfillment (annual output: millions of meters), ensuring on-time delivery and consistent quality with factory-direct prices.
Global Standard Compliance: Strictly compliant with ANSI B29.1, ISO 606 and DIN 8187, 100% interchangeable with international brands, reducing replacement costs.
