Industrial Rotary Unions

Moog rotary unions are used for the reliable transfer of media between stationary and rotating machine parts, supporting many media types, such as: oil, water, grease, emulsion as well as (compressed) air, gas or vacuum. Our rotary unions are designed for a variety of industrial applications, including packaging machines, semiconductors, machine tools, steel production machinery, automation, robotics and power generation.

We offer standard and customized, fully integrated solutions that can be combined with our electrical slip rings and fiber optic rotary joints. In addition, a wide range of speeds and pressures are offered.
