How to choose this product

rotary-union

Rotary unions are autonomous, self-supporting couplings that allow leak-less fluid transfer (steam, water, air, oil) to a rotating machine's extremities. They can have several channels and ports, enabling them to convey several fluids simultaneously.

Applications

Hydraulic applications for rotary unions are numerous: offshore operations, aeronautics, construction, automobile and other industries.

Technologies

The two collars of the device, one of stainless steel, the other of graphite, are in contact with one another. Each has a polished surface.

How to choose

Several parameters must be considered when choosing a rotary union:
- Rotation velocity
- Number of circuits and their diameters
- Fluid nature, temperature and pressure

Advantages

- Fluid passage
- Watertightness
- No maintenance
