Industrial gearboxes operate under high gear-tooth contact stress and demanding output torque requirements. CS Heavy Forgings delivers premium-grade industrial forging for gear box manufacturers, supplying high-density gear blanks, gear shafts, and seamless rings engineered to prevent premature gear tooth spalling and core failures.
Using precision open-die forging equipment, we compress steel alloys to eliminate core porosity. This ensures that when your gear cutters machine internal or external teeth, they work into a completely uniform structure with high structural stability.

Engineered for High-Wear Gear Tolerances
- Isotropic Material Properties: Our forging method yields uniform mechanical characteristics across all axes, preventing uneven gear-tooth wear under heavy loading conditions.
- Excellent Subsurface Cleanliness: Gear teeth experience intense localized shear stresses. Our clean steel melts minimize non-metallic inclusions, protecting against sub-surface fatigue cracking.
- Uniform Heat Treatment Response: Our blanks respond consistently to downstream carburizing, nitriding, or through-hardening treatments, ensuring precise surface-to-core hardness profiles.
Integrated Component Ecosystem for Transmission Systems
Streamline your gearbox manufacturing supply chain. We are manufacture of custom forged shafts and step shafts for planetary transmission lines, precision-finished forged rolls manufacturer assets, and large-diameter raw materials through our dedicated round bar manufacturer for traders network.
Frequently Asked Questions (FAQs)
- Can you supply gear blanks in a rough-turned or proof-machined state?
Yes. We deliver gear blanks and stepped gear shafts either black forged, rough-turned, or fully proof-machined to your exact target sizing dimensions, minimizing processing scrap at your gear hobbing stations.
- What is the maximum diameter capacity for seamless forged gear rings?
Our facility produces high-integrity forged gear rings and solid discs reaching diameters up to 1400 MM with custom thicknesses.
Forging grades for gearbox components
Gearbox shafts and highly loaded drive components are frequently specified in engineering alloy steels. Review EN19 forged shafts and EN24 forged shafts, then submit the drawing, standard, heat treatment and mechanical-property requirements for technical review.
