Single Passage

From our economical swivel unions to our more robust bearing supported rotary unions, available in 90 degree or inline, Rotary Systems’ line of single passage rotary unions is flexible enough for any application. Our knowledgeable Applications Engineers will recommend the best single passage swivel union or rotary union for your application.


SERIES RU001

90 Degree Swivel Unions
Rotary Systems’ entry level 001-Series swivel union is designed for the hose reel industry, where pressures may be high but rotational speeds and side loads are at a minimum. This economical swivel union uses a plated shaft and o-ring seals.


SERIES RU002

90 Degree Swivel Unions
Rotary Systems’ 90° swivel union is designed for the car wash industry. This swivel union uses a hardened and ground shaft, impregnated Teflon seals and Oilite® bronze bearings. The 002 swivel union series is able to withstand high pressures, moderate speeds, and moderate side loads.


SERIES RU003

90 Degree Swivel Unions with Bearings
Rotary Systems’ 90 degree swivel union is designed for heavy use. This economical swivel union uses a hardened and ground shaft, impregnated Teflon seals, and deep-groove ball bearings. The 003 series swivel union is able to withstand high pressures, moderate speeds, and high side loads.


SERIES RU004

90 Degree Swivel Unions for High Pressures
Rotary Systems’ 90 degree swivel union is designed for super-heavy-duty use. This swivel union uses a hardened and ground shaft, impregnated Teflon lip seals, and deep-groove ball bearings. The 004 series swivel union is able to withstand high pressures at moderate speeds.


SERIES RU006

Inline Swivel Unions with Bushings
Rotary Systems’ inline swivel union is designed for multipurpose use. This economical swivel union uses a hardened and ground shaft, impregnated Teflon seals, and Oilite® bronze bearings. The 006 series swivel union is able to withstand high pressures, moderate speeds, and moderate side loads.


SERIES RU008

High Speed Air/Hydraulic Rotary Unions
Rotary Systems’ Series 008 rotary unions feature mechanical face seal technology for low torque, high speed and moderate pressure applications. Found in air or hydraulic clutches, these rotary unions feature full flow design with Carbon Graphite-to-Carbide seals and stacked radial contact ball bearings.


SERIES RU030

High Speed Coolant Unions
Rotary Systems’ 030-Series coolant rotary unions are ideal fits for machine tool coolant or MQL (Minimum Quantity Lubricant) applications. These coolant rotary unions feature balanced Silicon Carbide mechanical seals and match-ground deep groove radial contact ball bearings with labyrinth bearing protection.


SERIES RU032

Hydrostatic Rotary Union

Rotary Systems’ hydrostatic rotary unions are designed for applications that require high speed and pressure simultaneously. The media creates a hydrodynamic seal in the shaft/housing interface for cool running with minimal torque. These hydrostatic rotary unions are available with one or two passages.

Multiple Passage

Our multiple-passage rotary unions are a convenient solution when you need to pass more than one type of media to and from rotating equipment. Cross talk between passages is virtually eliminated with our proprietary, carbon-fiber impregated Teflon® seal technology, which provides worry-free service. Available in standard or flange mount configurations, our entire line of multi-passage rotary unions feature a through bore for electrical slip rings, providing a complete solution for any application.

Coaxial Duo Flow Rotary Unions
Rotary Systems’ inline dual-flow swivel union is designed for multipurpose use. This swivel union uses a hardened and ground shaft, impregnated Teflon seals, and dual ball bearings. The 009 series swivel union is able to withstand high pressures, moderate speeds, and high side loads.


SERIES RU010

Coil Processing Rotary Unions
Rotary Systems’ dual port air / hydraulic rotary unions are designed for applications such as expanding mandrel drums on coil processing equipment. This rotary union uses a hardened and ground shaft, impregnated Teflon Seals, and ball bearings and is able to withstand high pressures at low speeds.


SERIES RU011

2 & 4 Pass Over-the-Shaft Rotary Unions
Rotary Systems’ exclusive over-the-shaft rotary union is designed for multipurpose use. This rotary union uses a hardened and ground shaft, impregnated Teflon seals, and dual ball bearings. The 011 series rotary union is offered in 2 or 4 passages.


SERIES RU012

2 Pass Threaded Shaft Rotary Unions
Rotary Systems’ multi-purpose 2-passage rotary unions feature threaded shaft connections, a recessed hardened and ground shaft, a through bore to accommodate electrical slip rings, deep groove radial contact ball bearings and carbon fiber impregnated Teflon Seals.


SERIES RU013

2 Pass Flange Mount Rotary Unions
Rotary Systems’ multi-purpose 2-passage, flange mount rotary unions feature a recessed shaft, through bore to accommodate electrical slip rings, a hardened and ground shaft, deep groove radial contact ball bearings and carbon fiber impregnated Teflon Seals.


SERIES RU014

3 Pass Threaded Shaft Rotary Unions
Rotary Systems’ multi-purpose 3-passage rotary unions feature threaded shaft connections, a recessed hardened and ground shaft, a through bore to accommodate electrical slip rings, deep groove radial contact ball bearings and carbon fiber impregnated Teflon Seals.


SERIES RU015

3 Pass Flange Mount Rotary Unions
Rotary Systems’ multi-purpose 3-passage, flange mount rotary unions feature a recessed shaft, through bore to accommodate electrical slip rings, a hardened and ground shaft, deep groove radial contact ball bearings and carbon fiber impregnated Teflon Seals.


SERIES RU016

4 Pass Threaded Shaft Rotary Unions
Rotary Systems’ multi-purpose 4-passage rotary unions feature threaded shaft connections, a recessed hardened and ground shaft, a through bore to accommodate electrical slip rings, deep groove radial contact ball bearings and carbon fiber impregnated Teflon Seals.
