Product Description

Product Description

    

        By adopting integrated optimum design of the structural dimensions, parts material and heat treatment process, the 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..
 

Category	Details
1. Ultra-High Strength	Made of premium alloy steel (e.g., SCM435) with advanced heat treatment (carburizing & quenching). Tensile strength 20%-40% higher than standard roller chains.
2. Superior Wear Resistance	Hardened surface treatment (HRC 45-60) on plates/rollers extends service life, ideal for high-load & frequent start-stop cycles.
3. High Fatigue Strength	Optimized hole design in link plates reduces stress concentration, enhancing performance under alternating loads.
4. Precision Transmission	Short pitch design (e.g., 12.7mm-38.1mm) ensures smooth operation, minimizes polygon effect, and suits high-speed applications.
5. Compact & Lightweight	10%-15% lighter than standard chains at equivalent strength, saving space and reducing inertial resistance.
