The first-stage sun shaft is a key output component in the planetary
Transmission System of a wind turbine gearbox. It directly connects to the sun gear, transmitting power to the next stage of the drive train. Our precision-machined sun
Shaft Forgings are based on high-strength forged shafts, ensuring optimal material performance through open-die
Forging and achieving high dimensional accuracy through advanced machining processes. These shafts provide reliable transmission solutions for wind energy and other industrial applications, ensuring long-term operational stability.
Each precision sun shaft reflects our commitment to meeting the demanding requirements of modern wind energy applications, offering main gearbox manufacturers a dependable, high-performance power transmission solution.
