The state of our unions is strong.
We’ve never been one to turn down a challenge or fail to meet the toughest, most stringent demands and needs of our customers. This is what has made Rotary Systems the industry leader in the design and manufacture of standard and custom rotating unions and electrical slip rings.
A rotary union is a mechanical device that allows the transfer of fluids and/or gases to and from rotating equipment. They are utilized in machinery that requires a constant flow of lubrication, air, or other liquids during rotation.
A slip ring is a device that allows the transfer of electrical power, signals and data to and from rotating equipment.
Rotary Systems is the only manufacturer to offer diverse rotary union technologies such as mechanical seals, Teflon seals, hydrostatic seals and integrated or stand alone electrical slip rings. For over two decades, engineers around the world, in numerous industries, including Automation, Defense, Offshore, Semi-Conductor, and Food and Beverage processing, have counted on our 35 years of combined engineering expertise—the most in the industry—to turn their visions into reality. Rising to the task, time and again, Rotary Systems has custom built over 700 unique rotating unions and slip ring assemblies to date.
The demands and uses of rotary unions and slip rings are vast, which is why our standard and custom built assemblies are available in numerous material, seal and passage size options. Our unions are available with an integrated electrical slip ring option to transfer power, signal, or data with one complete assembly. Alternatively, our slip rings are available as a standalone arrangement.
From our skilled engineers and workers to our state-of-the-art facility to our incredible depth of knowledge, you can trust Rotary Systems to always deliver rotating unions and slip ring solutions deigned and built to the highest standards possible. Yours.
