Rotary Joint

Rotary joints are used when transferring hydraulic oil and other fluids e.g. from nacell to the rotating hub in turbines using e.g. hydraulic pitch system.

​

High quality, robustness and long lifetime of the Rotary Joint used are essential if turbines are expected to run year after year with high availability, low maintenance and to eliminate loss of hydraulic oil creating dirty and dangerous operation.

​

Wind Cluster cooperate with the most experienced manufacturers of rotary joints.

​

Rotary joints are components connecting stationary pipes to rotating rollers and tables for transferring media under pressure and to heat or cool a system or to feed the media through for process.

​

We work with solution for oil up to 390°C/734°F, hydraulic oil up to 350 bar, air up to 40 bar, chemical media, coolant up to 150 bar, vacuum and high running speeds and temporary “dry run” applications.

​

Rotary joints are unessential compared to the cost of a wind turbine. But they are essential components for the performance and safety. Critical usage configurations require theoretical and hands-on knowledge with a variety of applications.​
