SU (Super Ultimate) and H (Heavy) Series ChainsBLink-Belt ® SU and Rexnord ® H series chains differ from standard roller chains in sidebar thickness and in pin material and heattreatment. The combination of increased sidebar thickness and high hardness alloy through hardened pins results in greateraverage ultimate tensile strength ratings for the SU and H series chains. The SU and H chains are capable of withstandinghigher operating and intermittent shock loading without reduction of pin-bushing wear life.Multiple width SU and H series chains are available.SU and H series single strand roller chains operate on standard series roller chain sprockets. However, multiple strand heavyseries chains require sprockets with rows of teeth with wider spacing to accommodate the thicker chain sidebars.
