Hydraulic disc brake for wind turbine
max. 170 kN | WBA4-90
Carlisle Industrial Brake and Friction
Overview
The WBA4-90 has been specifically designed to meet the exacting requirements of Wind Turbine yaw and rotorbraking applications, where high braking and holding torques are required over long operational periods. The WBA4-90 is constructed from ductile cast iron, has two symmetrical halves each containing two 90mm diameter pistons, and features a proprietary piston seal and protection boot design. This unique combination of features ensures that the WBA4-90 provides reliable long term operation over extremes of environmental conditions, and simplified in-service inspection and maintenance for the duration of the Wind Turbine's lifetime.
Features
* Hydraulically applied brake
* Carlisle NoiseFree organic (non-asbestos) linings
* Large brake lining area for reduced wear and operating temperatures
* Grooved and tapered linings for improved performance and lifetime
* Hydraulic drain ports to prevent oil contamination on the brake disc
* Small air gap (between disc and lining) for minimum brake reaction time
* Few moving parts for increase lifetime and easy maintenance
* Suitable for horizontal or vertical installation
* -40°C to 70°C operational range
