Steel Large Pitch Sprocket

 This Large Pitch Sprocket is a heavy‑duty power transmission component designed for crawler excavators, bulldozers, heavy conveyor systems, mining equipment, and industrial chain drives. It is manufactured by our in‑house Sand Casting + CNC precision machining process. The use of ZG40Cr cast alloy steel provides an excellent balance of high tensile strength, good toughness, excellent wear resistance, and reliable performance under heavy shock loads and continuous operation. The sand casting process ensures the ability to produce large‑diameter, heavy‑weight sprockets with precise tooth profiles, generous fillets, and cost‑effective tooling — all critical for large pitch sprockets requiring accurate chain engagement, high load‑carrying capacity, resistance to tooth wear and plastic deformation, and long service life in demanding industrial environments.

Our one‑stop approach — covering pattern design, sand casting, CNC machining, heat treatment (quenching & tempering), tooth surface hardening (induction or flame hardening), surface finishing (shot blasting or protective coating), and engineered packing — delivers a ready‑to‑install sprocket that meets high‑strength mechanical requirements and withstands severe impact, abrasive wear, cyclic fatigue, and heavy tensile loads.
