2. •In mechanical systems, there are various components that play a critical
role in the application. One example of such components is rotary unions.
•A rotary union or swivel joint is a mechanism used to transfer fluid (under
pressure or vacuum) from a stationary inlet to a rotating outlet. Thus, it
preserves and isolates the fluid connection.
•Rotary unions are also called rotary joints or rotary couplings. They are
called fluid swivels or swivel joints as well.
•Rotary unions are engineered to endure a large range of temperatures,
pressures, and speeds for a wide range of conditions and environments.
•Rotary unions typically function by connecting to input and securing onto
another mechanism while it allows a moving connection to be preserved.
•Rotary unions are used in many applications; from miniature rotary unions
to the semiconductor industry, from large and rugged-duty rotary unions
for industrial applications.

3. 1) Air rotary unions
There are three types of rotating unions
•These unions build reliable rotating unions for high-performance
applications where applications need high pressures and high
speeds. These unions are categorized by four categories:
one-channel air unions
low-speed one-channel unions
low-speed multi-channel unions
dual passage air unions

4. 2) Coolant
•Coolant rotary unions offer many capabilities to bring down overall
maintenance cost. Coolant rotary union is bearing less.
•It has a compact design with a high RPM because there is no
presence of bearings. It reduces the overall cost. The off-the-shelf
rotating unions offer many configurations that can fit any machining
application.
3) Hydraulic unions
•Reliable hydraulic rotary unions are known for their utility in high
speed, high-pressure applications. They are available in a variety of
mounting configurations. Hydraulic unions are available in many
sizes to fit small spaces. These unions are constructed for harsh
environments.

5. How does a rotary union function?
•A rotary union locks onto an input valve when it rotates so that it
can meet an outlet. During this time, the liquid and/or gas flows into
the rotary union from its source and it is held within the device
during its movement.
•The liquid and/or gas leaves the union when the valve openings
meet during rotation, and it results in the flow of more liquid and/or
gas into the union again for the next rotation.
•A rotary union is designed to rotate around an axis. It often
functions under high pressure and constant movement. The design
of a rotary union can be altered to change it or to increase the RPM
or PSI it is supposed to withstand, and the number of valves
required.

6. •Rotary unions are available in several sizes, shapes, and
configurations. However, the four fundamental components that
always remain constant are: a housing unit, a shaft,
a bearing (mechanical) (or bearings), and a seal.
•Rotary unions are made from stainless steel in general because
stainless steel resists rust and corrosion. However, they are made
from other metals like aluminum. Some rotary unions have multiple
ports, and they can handle different types of material
simultaneously. These versatile components are widely used in
several applications.
