Super H Roller Chain ANSI | Single Pitch | Heavy Duty | SUP H “SUP H” type roller chains have the same link plates thickness as the next larger chain size. Enhanced plate configuration and ball milling plate holes ensure greater tensile strength and resistance to fatigue failure. High-grade alloy steel and four point riveting provide higher shock load capacities. Average Tensile Strength Connecting links for SUP H type are “semi press-fit” style. SUP H type multiple strand chains are standardly designed for semi press-fit center plate construction. BCL con-necting links are standardly equipped for SUP H type multiple strand chains. Offset links are not available. SUP H type chains are also available in the cottered type design. Contact SUGIYAMA for further information. SUP H type chains are designed to be used with standard sprockets. SUP H type multiple strand chains are not designed to be used with standard sprockets.
