Precision Steel Gears Alloy Powdered Steel For Forging For Wind Turbine Gearbox

Our Precision Alloy Steel Forged Gear for Wind Turbine Gearbox Application is engineered to deliver exceptional performance and durability in harsh wind power environments. Manufactured using high-grade alloy steels such as 18CrNiMo7-6 and 42CrMo4, this forged gear offers superior hardness, wear resistance, and load-bearing capacity—making it ideal for main drive, yaw, and pitch gearboxes in both onshore and offshore wind turbines.

With advanced forging and heat treatment processes, each gear maintains optimal microstructure integrity and dimensional accuracy, ensuring long-term reliability and minimal maintenance. Ultrasonic testing (UT), magnetic particle inspection (MPI), and other non-destructive tests are performed to meet international quality standards.

Key Features:

• Material options: 18CrNiMo7-6, 42CrMo4, and more

• Gear types: helical, spur, and customized profiles

• Surface treatment: case hardening, quenching, tempering

• Precision machining with CNC for high accuracy

• Applications: wind turbine main gearbox, yaw & pitch systems

Application Industries:

• Onshore and offshore wind energy

• Renewable power generation systems

We provide custom forging solutions to match your specific gearbox requirements. Contact us to learn more about our wind power forging capabilities.
