A rotary joint, also referred to as a rotary joint or rotating joint, provides a mechanical seal between a stationary supply pipe and a rotating drum or cylinder to permit the flow of heat transfer media into and/or out of the rotating roll. Heat transfer media typically used with rotary joints and rotating joints includesteam,water,hermal oil,coolant,airhydraulic oil.
G series rotary joint consists of two large precision bearings and seals principles of design using smooth, sealed bearing and wear to a minimum, extend the service life.


JARCH’s high-speed rotary unions are capable of containing very high pressure while rotating at high speeds. The materials used in the making of the high-speed rotary unions are aluminum, carbon steel, and, upon request, stainless steel, which provides outstanding corrosive resistance. We offer a variety of sizes in both American and Metric. We specialize in custom design that provides our customers with the exact specifications that they require. Speak to our knowledgeable and personable sales staff and they will be happy to assist in the creation of the prototype that will meet your needs.


Typical industrial uses for JARCH’s high-speed rotary unions include steam dryers, rubber mills, extruders, calendar rolls, air clutches, laminators, press rolls, manufacturing of machines, hydraulics, Machining Centers and related applications. 


1. High-temperature,high-pressure resistant rotating pipe coupling

2. Rugged-construction unions suitable for high pressure, high temperature thermic oil, steam

3The seal is imported from Germany, which guarantee the excellent performance of our rotary union.

4. The design of detachable baseplate structure is convenient for the conversion between single and multi-passsages

5. The use of graphite pallet  balance the compensation of spring, hence it avoids the spring being corroded and prolongs the service life.

6. Ideal for thermal oil and for considerably higher pressures, temperatures

7. Hosing made of ductile cast iron and cover&rotor made of chrome steel

8. Have high temperature resistant spring

Installation Instructions:
Your Rotary Systems rotary union is a precision component which, when installed properly, will provide a long, leak free life. Please follow these general guidelines when installing your union:
Rotary Systems unions should always be installed using flexible connections.  To avoid damage to the bearings, the union needs to find its center during operation.  It is imperative that either the shaft or the housing is not hard-piped.  
The housing of the union should be held in a vise and the flexible connection should be installed before installing the union to the machine.
Clean female threads and face of shaft prior to installation. Use Teflon pipe tape or pipe sealant on NPT threads. As a guideline, NPT threads should be hand tight plus 1- 3 turns to seal the threads. When installing parallel threads, appropriate gaskets or o-rings should be used.
There should be a slight, kink-free curve in the hose when installed on the equipment. It is essential the housing or shaft is allowed to float to compensate for any eccentricities and/or misalignment.
In many instances, the flexible hose connections are used for anti-rotation. Other applications require an external device for anti-rotation such as a fork around the fittings, pin, yoke or bracket.  Anti-rotation devices need to “float” to prevent damage to the union.  
To prevent damage to the shaft or the seals, Rotary Systems requires filtration to 10 microns or less.  Failure to do so may invalidate your warranty and cause premature failure.
If your union has grease fittings, lubricate union with no more than two pumps of appropriate grease per fitting.
