High strength short pitch roller chains

Simplex, Duplex & Triplex strands
By adopting integrated optimum design of the structural dimensions, parts material and heat treatment process, the ultimate tensile strength of SP series high strength roller chain is 28% more than that of A series standard roller chain. Moreover, it has excellent performances of fatigue strength and impact resistance etc
