Custom 20CrMnMo Alloy Steel Forgings 42CrMo4 42CrMo Gearboxes Drive Shaft Forgings

Custom Alloy Steel 20CrMnMo 42CrMo4 42CrMo Drive Shaft Forgings For Industrial Gearboxes. We manufacture high-strength forged drive shafts from premium alloy steels such as 20CrMnMo, 42CrMo4, and 42CrMo, designed for use in industrial gearbox systems that demand high torque transmission, fatigue resistance, and dimensional precision.

Key Features:

• Materials:

  • 20CrMnMo: Ideal for carburized gearbox components with high surface hardness

  • 42CrMo / 42CrMo4: Excellent strength, toughness, and wear resistance

• Forging Method: Open die / free forging

• Heat Treatment: Normalizing and tempering

• Machining: As-forged, rough machined

• Unit Weight: Up to 7 tons

Applications:

• Drive shafts and transmission shafts in industrial gearboxes

• Pinion shafts, coupling shafts, and gear spindle components

• Gearbox internals for wind power, mining, metallurgy, and heavy machinery

Advantages:

• High load-bearing capacity and torsional strength

• Superior material uniformity through precision forging

• 100% ultrasonic tested and dimensionally inspected

• Custom lengths, diameters, and spline profiles available
