About #240H-3 Cottered Roller Chain
ANSI #240H-3 triple-strand cottered roller chain conforms to ANSI B29.1 standard. This heavy-duty chain adopts thicker link plates than standard #240 chain, delivering high tensile strength and excellent shock resistance. Cotter pin design supports easy on-site assembly and disassembly. Pitch: 3" (76.2mm). Made of heat-treated alloy steel with solid rollers and shot-peened plates, it features superior wear and fatigue performance. Applied to heavy power transmission for mining, construction and large industrial equipment.
