Alloy Steel Rotating Shafts Are Used In Large Industrial Equipment100-7000kg Custom Solutions. Our alloy steel rotating shafts are designed for heavy-duty industrial applications, with weights ranging from 100 kg to 7000 kg. Forged from high-strength materials such as 42CrMo, 4140, or 18CrNiMo7-6, these shafts provide excellent torsional strength, fatigue resistance, and stability under continuous operation.

They are widely used in power transmission systems of large-scale equipment, including wind turbines, port cranes, mining machines, and metallurgical gearboxes. With precision forging, heat treatment, and optional rough or finish machining, each shaft is tailored to meet customer specifications and performance requirements.

Key Features:

• Weight Range: 100–7000 kg

• Materials: Alloy steel grades including 42CrMo, 4140, 18CrNiMo7-6

• Applications: Wind power, heavy equipment, port machinery, metallurgy

• Condition: As forged, rough machined

• Services: OEM customization, drawing-based production, mechanical testing

Advantages:

• Superior load-bearing and rotational performance

• Enhanced fatigue life and dimensional accuracy

• Full traceability and quality inspection (UT, MPI, hardness, etc.)

• Flexible sizing and machining to suit project needs

The steel forgings production flow:

raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
