Rotary Unions, Slip Rings and Combinations

Your benefits

High system availability

GAT hydraulic rotary unions and slip rings allow correct adjustment of blade pitch to wind direction, even under rough conditions.

Reliable and profitable

Our slip rings with proven gold/gold technology provide an excellent transmission of power, signals and data. Compared to commonly used carbon brushes, wear is reduced to near zero. Our maintenance-free rotary unions have been in use successfully for many years in on-shore and off-shore applications. They are characterized by a long service life and robustness.

Combinations without limits

At GAT, any combination of rotary unions and slip rings can be realized. Thanks to the quick-exchange system, individual components can be easily and quickly replaced.
