Showa Giken Kogyo Pearl Rotary Joint RX Series

The floating seal ring provides high conformity to the rotor seal surface and stable sealing performance.
To meet various applications. A wide range of options are available.
Low torque means that in many cases no construction to prevent the casing from rotating is required. (Except for RXK).
No need for lubrication because of the use of sealed ball bearings.
The standard mechanical seal is a combination of special carbon and ceramic. For RXE/RXH, ceramic can be changed to carbide as a semi-standard specification. Dry air compatible products are also available. What is
a rotary joint? It realizes the supply and discharge of all kinds of fluids at high and low rotation.
Pearl rotary joints are used to supply and discharge pressurized fluids and fluids below atmospheric pressure from fixed piping to the rotating parts of various machines and equipment without leaking at all.
It is an extremely effective and economical rotary joint developed based on the theory of recent advanced mechanical seals, and is manufactured under strict quality control, so the product is consistent and interchangeable.
