Machined Alloy Steel Sun Shaft Forging

Machined Alloy Steel Sun Shaft Forging

Sun Shaft: The Core Power Output Shaft of Wind Turbine Gearboxes The sun shaft is a critical transmission component in wind turbine generator systems — a high-speed rotating power shaft responsible for torque transmission, centering, and supporting complex loads. Our precision-machined sun shafts are made from high-quality 18CrNiMo7-6 alloy steel, produced through a complete and controlled process chain that enhances torsional and fatigue resistance. Designed to meet the high-load requirements of medium and large-scale power generation equipment, they deliver exceptional strength, accuracy, and reliability.
