Description
Huawu SB Series Wind Turbine Rotor Disc Brakes
Huawu SB rotor disc brakes provide hydraulically applied braking for wind turbine rotor systems. These normally open brakes use spring release and a symmetrical twin-cylinder arrangement.

| Wear adjustment | Piston-stroke adjustment |
| Maintenance features | Pad wear indication and replaceable pads |
| Enquiry options | Release switch, wear-limit switch, friction material and oil collection |
| Configuration | One selected brake model; hydraulic unit and disc specified separately |
Application and selection
For rotor-brake replacement and brake-system integration enquiries. Clamping force is not braking torque; the disc radius, friction material and system pressure must be checked against the turbine design.
Quotation information
Send the existing brake model, disc dimensions, mounting drawing, hydraulic pressure, required braking duty and quantity. Confirm the complete braking arrangement with the responsible turbine engineer.
Supply availability, final configuration and warranty terms are confirmed in the written quotation.
