Introduction
to Rotary Unions
A Rotary Union is a device which can be connected to a rotating
shaft and allows for the leak-proof transfer of fluids to and from
a stationary source service. When selecting the correct rotary
union model for your particular application, the vital components
to consider include the rotary seals and the bearing support
systems.
ROTARY SEALS
1) Filton® Bellows Seal
For the majority of applications, the Bellows Seal is the most
efficient seal used. It does not contain any elastomeric components
which make it suitable for rotary applications ranging in ambient
temperatures from subzero to 300oC. It is particularly useful for
steam, hot water and heat transfer applications.
2) Filton® Mechanical Seal
The Mechanical Seal is generally used for higher pressure and
higher speed applications such as hydraulic systems and machine
tools. It is also used in applications where higher speed shafts
are involved. The springs of the mechanical seal are located
outside of the fluid flow area which improves performance.
Both variations of seal provide exceptional quality of the seal
contact faces; each are lapped to a high degree of accuracy and are
checked optically to ensure that the correct flatness is obtained.
BEARING SUPPORTS SYSTEMS:
Depending on your application, there are a range of different
bearings that are available including standard ball bearings,
angular contact bearings, carbon journal and thrust bearings.
Although the ball bearings used generally have an upper temperature
limit of 180°C, they are more suitable for higher speed
applications and the upper temperature limits can be exceeded in
some cases with special bearings and lubrication. Carbon bearings,
although they have lower speed limit values, are useful for higher
temperatures up to 300°C. For more information about bearing
options, please Contact Us.
