Product Description

The generator shaft is the central rotating element of electric motors and generators, responsible for torque transmission, rotor support, and withstanding dynamic loads. Its strength, balance, and fatigue life directly affect the reliability and efficiency of the entire system. As a pre-machining forged blank, the optimized fiber flow from forging provides an excellent base for turning, grinding, and dynamic balancing in later stages.

Applications

Our generator shaft Forged Blanks are key components in rotating power systems, mainly used in wind turbine generators but equally suitable for other industrial drive applications:

Wind Power Generation – Rotor shafts in doubly-fed and permanent-magnet generators.
Hydropower – Water turbine generator shafts, connecting the turbine and generator.
Marine Propulsion Systems – Propulsion and generator shafts in marine engines and auxiliary drives.
Industrial Motors – High-performance shafts for medium to large variable-frequency and high-voltage motors.
Rolling Mills / Metallurgy – Shafts in rolling mill drives and industrial compressors, requiring high fatigue and torsional strength.

Produced via open-die forging with diameters starting from 100 mm and weights up to 8 tons, these carbon steel and alloy steel forgings deliver excellent mechanical balance. Full machining and dynamic balancing services are available to meet customer specifications within an integrated supply chain.

We offer machining to finished shafts for generators and turbine applications. Besides forges shafts, both semi-finished blanks and fully Machined Shafts are available. See our related machined shaft products for details.
