Huawu SB-A Wind Turbine Hydraulic Yaw Brakes
Huawu SB-A yaw brakes use hydraulic application and spring release for wind turbine yaw systems. They support yaw damping, positioning and controlled cable untwisting in a matched turbine design.

Application and selection
For yaw-brake replacement and engineered brake packages. Match hydraulic pressure, mounting dimensions, disc condition and friction material to the turbine duty; clamping force must not be treated as braking torque.
Quotation information
Provide turbine and brake nameplates, mounting drawing, disc dimensions, hydraulic schematic, required clamp force and quantity.
Supply availability, final configuration and warranty terms are confirmed in the written quotation.
