Besides designing, building and repairing hydraulic cylinders, WDH also has years of experience in designing and building rotary joints. For some demanding customers it is not possible to use standard solutions, so therefore we took the initiative and designed our own solution. Rotary joints that can handle extreme conditions such as high rotation speed combined with high pressures and huge diameters.
For example, recently WDH designed and build this cooling water rotary joint with 2 passages. The rotary joint ensures that there is no limitation in the rotation angle and is mounted on a slip ring in an offshore crane.
Diameter Ø 600 mm
