#100-3 triple roller chain complies with ANSI B29.1 standard, featuring a 1.25-inch pitch three-row structure for extreme heavy-load power transmission. Manufactured from high-strength carbon steel, pins, rollers and side plates are precisely heat-treated to enhance tensile strength, wear resistance and fatigue resistance.
Compared with single and double-strand chains, this triple-strand design provides larger load capacity and stable transmission with low friction. It is fully compatible with standard #100 sprockets for convenient mounting and replacement. Ideal for heavy-duty conveyors, large agricultural machinery, mining equipment and industrial driving systems, ensuring consistent long-term operation with minimal maintenance expense.
