All About Extra Heavy Roller Chain (HE)

• "HE" type roller chains are designed with thicker link plates to ensure greater capacity for absorbing shock loads without fatigue failure of side plates.
• They are also made with high quality alloys and through-hardened pins to better resist fatigue failure.
• Connecting links are "cotter" style for size 80 HE.
• HE type multiple strand chains are standardly designed for loose-fit center plate construction.
• HE type multiple strand chains can be constructed with semi press-fit center plates upon request.
• BCL connecting links are standardly equipped for HE type multiple strand chains with semi press-fit center plate construction.
• HE type chains are designed to be used with standard sprockets. HE type multiple strand chains are not designed to be used with standard sprockets.
• Takes account of a 35% reduction of fatigue strength when a single pitch offset link is used.
