SP Series Simplex Strands Roller Chain High Strength Short Pitch
By adopting an integrated optimum design of the structural dimensions, parts material, and heat treatment process, the ultimate tensile strength of the high strength SP series roller chain is 28% more than that of the A series standard roller chain. Moreover, it has excellent performances of fatigue strength and impact resistance, etc.
