lightweight & noise-free systems for wind turbine braking and gliding
DELLNER BUBENZER offers lightweight, noise-free systems for braking and gliding processes in wind turbines. Noise reduction has been the core focus in the development of this comprehensive range of brakes and sliding bearings, recognizing that noise prevention plays a substantial role in the overall acceptance of wind energy.
A hydraulic rotor lock offering up to 250 bar pressure with an activation time of 60 seconds.
We offer three models of the JHS-RLH-240 hydraulic rotor lock – the GL Type Certified JHS-RLH-240, the JHS-RLM-240 and the JHS-RLH-240-154. All these locks deliver up to 250 bar pressure with an activation time of just 35 seconds.
Manually activated rotor lock used for safety purposes during maintenance operations to stop the rotor mechanically. The maximum lateral force is 6400 N and the standard stroke is 95 mm. Other strokes are available upon request.
A hydraulic active rotor brake with a braking force of 44 kN that’s been specially developed for use in damp, dusty and corrosive working environments
Due to its high capacity, our SFRA brake is mainly used as a rotor brake in wind turbines. It is particularly suitable for applications with a high duty cycle.

JHS WTC is a flexible disc coupling mounted between gearbox and generator. It's a tailor-made solution for wind turbine applications (Type WTC = Wind Turbine Coupling).
A hydraulic active yaw brake with GL Type Certification and braking force of 620 kN.
A passive yaw sliding bearing with a robust yet simple design that guarantees optimum performance throughout the life of the turbine.
