E Roller Chain ANSI | Single Pitch | Heavy Duty | E “E” type roller chains are made using high quality alloys and through-hardened pins to better resist fatigue failure in applications that are subject to high shock loads. Please specify if the chain is being utilized in oil held applications. Average Tensile Strength Connecting links are “cotter” style for size 80 E. E type multiple strand chains are standardly designed for loose-fit center plate construction. E type multiple strand chains can be constructed with semi press-fit center plates upon request. BCL connecting links are standardly equipped for E type multiple strand chains with semi press-fit center plate construction. Takes account of a 35% reduction of fatigue strength when a single pitch offset link is used.
