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.
Hydraulic applications for rotary unions are numerous: offshore operations, aeronautics, construction, automobile and other industries.
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.
Several parameters must be considered when choosing a rotary union:
- Rotation velocity
- Number of circuits and their diameters
- Fluid nature, temperature and pressure
- Fluid passage
- Watertightness
- No maintenance

Single-channel rotary union max. 12.5 bar, max. 2000 rpm | 301 MOOG
The Model 301 is a single pass fluid rotary union. It can be operated as a stand alone FRU. Its design has been optimized to allow an AC4598 / AC6200 electric slip ring (ESR) to be mounted directly on the Model 301 body, simplifying the integration and mounting arrangement. The Model 301 utilizes sealed-for-life rolling element bearings...
