Heavy-Duty Forged Gear Shafts – 42CrMo ,42CrMo4, 18CrNiMo7-6 for Transmission Shaft. Our heavy-duty forged gear shafts are engineered for high-load transmission systems, utilizing premium materials such as 42CrMo, 42CrMo4, and 18CrNiMo7-6. These alloys offer outstanding toughness, fatigue strength, and heat treatment response, making them ideal for demanding industrial applications.
Each shaft is forged to refine grain structure, improve internal quality, and ensure superior mechanical performance. With precision machining, these shafts are well-suited for use in wind turbine gearboxes, industrial drives, mining equipment, and other power transmission assemblies requiring reliable torque transfer.
