Forged Steel Gear Blanks | Custom Large Diameter Ring Forgings for Heavy Machinery
Product Description
Start your manufacturing process with superior integrity using Yile Machinery’s Big Steel Gear Forging Blanks. As the foundation for high-performance gears, our blanks are engineered to withstand the extreme torque and stress of heavy industrial applications.
We specialize in producing custom forged gear blanks (rings, discs, and hubs) that serve as the raw material for spur gears, helical gears, and herringbone gears. Unlike cast alternatives, our Open Die Forging and Rolled Ring Forging processes align the metal’s grain flow with the contour of the part, delivering exceptional impact toughness and fatigue resistance.
Key Features & Manufacturing Quality
Superior Metallurgical Structure: Our forging process eliminates internal porosity and defects common in castings. The refined grain structure ensures the final gear will handle high-load transmission without failure.
Custom Material Selection: We forge a wide range of materials to meet your specific mechanical property requirements, including Carbon Steel, Alloy Steel, and Stainless Steel.
Near-Net Shape Forging: We produce blanks close to your final dimensions. This "near-net" approach significantly reduces your machining time and material waste, lowering your overall production costs.
Heat Treatment Capabilities:
Normalizing/Annealing: To improve machinability for your CNC operators.
Quenching & Tempering (Q&T): To achieve specific hardness and strength levels before final machining.
Rough Machining Services: We can deliver blanks in "Black" condition (as-forged) or "Rough Machined" (pre-turned) to remove the oxide scale and prepare them for your finishing steps.
