100KG - 7000kg Free Forging Planetary Gear Shaft For Transmission Systems

42CrMo Free Forged Planetary Gear Shaft for Heavy-Duty Transmission Systems. Our 42CrMo free forged planetary gear shafts are designed for high-performance transmission systems operating under heavy loads, high torque, and continuous duty cycles. Manufactured through precision open-die forging and heat treatment, these shafts offer superior strength, toughness, and dimensional stability essential for critical powertrain components.

Key Features:

• Material: Made from premium 42CrMo alloy steel, offering high tensile strength, excellent hardenability, and outstanding fatigue resistance.

• Forging Process: Open-die free forging ensures directional grain flow, minimizing internal defects and enhancing mechanical performance.

• Heat Treatment: Quenched and tempered to achieve optimal hardness, toughness, and wear resistance; stress-relief annealing available for added dimensional control.

• Machinability: Rough or semi-finished machining available for gear spline, shaft ends, and bearing interfaces to meet specific design requirements.

• Forging Ratio: ≥ 3.0 — critical for high fatigue strength in rotating applications.

Applications:

• Planetary gear systems in wind turbine gearboxes

• Heavy-duty transmission systems in mining, construction, and industrial equipment

• Drive components in off-highway vehicles and metallurgical machinery
