Our roller chain not only has ball swaged holes to ensure accurate chain pitch (and therefore even loading around sprockets) but ball swaging and shot peening of the links develops compressive stresses. HIGH FATIGUE RESISTANCEĭue to the high loads transmitted by transmission roller chain, fatigue failure is a common occurrence especially when shock loading is present within the application. With a wide range of additional supporting products such as taper bushes, cone clamps and torque limiters you can be assured that keeping you moving is within our power transmission range. Whether you require British Standard, ISO or the ANSI standard of roller power transmission chain, Challenge is a leading supplier of both chains and sprockets all over the world. With shot peened link plates and ball swaged holes increasing the fatigue resistance, deep wasted link plates upgrading the breaking load and reducing stress, induction hardened precision pins increasing the chains operating life, pre stretching to ensure component alignment with minimal initial elongation and extended service life and optional spin riveting greatly improving link plate security in demanding applications, the Challenge range of precision roller transmission chains are keeping a wide range of industries moving all around the world. Roller transmission chains are one of the key products that have made Challenge so successful over the last 40 years. The link plate thickness has also been increased over the standard roller chain in order to increase the breaking load. ANSI Cottered Heavy Duty Series Roller Chain Every pin cottered on one side for ease of assembly and disassembly - making repairs or length shortening of the chains more convenient.
