The W SFRA 5 active caliper brake features an excellent capacity, making it ideal for use as rotor brakes on wind turbines. In order to achieve best results, it should always be noted if brakes are to be used in high duty cycle applications. These brakes use hydraulic activation and spring release. They are equipped with sintered linings and feature a horizontal compensation of +/- 5 mm, with support for direct gearbox installation. Additional options include limit switches for release and wear control, hydraulic power units, brake discs and couplings, seals designed for specific fluids, remote monitoring and diagnostic sensors (temperature, wear and release gap monitoring) as well as rotor locking pin and temperature sensor.
