Shaft-mounted rotary union
Rotary Systems, Inc.
Rotary Systems designs and manufactures a line of standard and custom over-the-shaft rotary unions.
The rotary union shown is constructed from carbon steel and utilizes a precision ground shaft, radial ball bearings and Teflon seals. This is a two passage rotary union with .25" NPT passages with a four inch bore through the shaft. This union was designed specifically for a high pressure hydraulic indexing application.
Our standard over-the-shaft line of rotary unions can be viewed on our website by clicking on the 011 series. Our standard unions are offered in two and four passages with a .5", 1.5” or 2.0” bore through the shaft. The bore through the shaft is independent from the union. Some customers will pass a shaft or electrical wires through this bore.
If you have a custom rotary union application, please contact our Technical Sales department at 1-800-959-0146.
