Drop forged rivetless chains are robust, high-strength chains designed for heavy-duty conveying applications, such as overhead and trolley conveyors. Made from heat-treated, drop-forged alloy or carbon steel, they consist of three main components—inner links, outer sidebars, and pins—that allow easy assembly and disassembly without tools. Their open structure prevents material buildup, making them ideal for industries like automotive, meat processing, and mining. Features include precise pitch control, smooth bearing surfaces for extended wear life, and resistance to impact and fatigue, ensuring reliable performance under harsh conditions.
